Raw liquid waste treatment process. A raw sewage treatment process is disclosed in which substantially all the non-dissolved matter, which is suspended in the sewage water is first separated from the water, in which at least organic matter is dissolved. The non-dissolved material is pyrolyzed to form an activated carbon and ash material without the addition of any conditioning agents. The activated carbon and ash material is added to the water from which the non-dissolved matter was removed.

The activated carbon and ash material absorbs organic matter and heavy metal ions, it is believed, are dissolved in the water and is thereafter supplied in a counter current flow direction and combined with the incoming raw sewage to facilitate the separation of the non-dissolved settleable materials from the sewage water. The used carbon and ash material together with the non-dissolved matter which was separated from the sewage water are pyrolyzed to form the activated carbon and ash material.

Energy requirements for waste water treatment. The actual mathematical models describing global climate closely link the detected increase in global temperature to anthropogenic activity. The total power contained in our nutrition is in the range of 0. The organic pollution of domestic waste water corresponds to approximately 0. The nutrients contained in the waste water can also be converted into energy equivalents replacing market fertiliser production. This energy equivalent is in the range of 0.

The annual mean primary power demand of conventional municipal waste water treatment with nutrient removal is in the range of 0. In principle it is already possible to reduce this value for external energy supply to zero. Such plants should be connected to an electrical grid in order to keep investment costs low.

Peak energy demand will be supported from the grid and surplus electric energy from the plant can be is fed to the grid. Zero 'carbon footprint' will not be affected by this solution. Energy minimisation must never negatively affect treatment efficiency because water quality conservation is more important for sustainable development than the possible reduction in energy demand.

This argument is strongly supported by economical considerations as the fixed costs for waste water infrastructure are dominant. Jet Lowe - U. Bulky waste quantities and treatment methods in Denmark. Bulky waste is a significant and increasing waste stream in Denmark.

However, only little research has been done on its composition and treatment. In the present study, data about collection methods, waste quantities and treatment methods for bulky waste were obtained from two municipalities. In addition a sorting analysis was conducted on combustible waste , which is a major fraction of bulky waste in Denmark. The amount of combustible waste could be significantly reduced through better sorting.

Many of the waste fractions consisted of composite products that underwent thorough separation before being recycled. The recyclable materials were in many cases exported to other countries which made it difficult to track their destination and further treatment. An important advantage of use of an aerobic biostabilization of waste prior to its disposal is that it intensifies the decomposition of the organic fraction of waste into the form which is easily assimilable for methanogenic microorganisms involved in anaerobic decomposition of waste in the landfill.

In this article it is presented the influence of aerobic pre- treatment of waste as well as leachate recirculation on susceptibility to biodegradation of waste in anaerobic laboratory reactors. Treatment of halogen-containing waste and other waste materials. A process for treating a halogen-containing waste material. The process provides a bath of molten glass containing a sacrificial metal oxide capable of reacting with a halogen in the waste material.

The sacrificial metal oxide is present in the molten glass in at least a stoichiometric amount with respect to the halogen in the waste material. The waste material is introduced into the bath of molten glass to cause a reaction between the halogen in the waste material and the sacrificial metal oxide to yield a metal halide. The metal halide is a gas at the temperature of the molten glass. The gaseous metal halide is separated from the molten glass and contacted with an aqueous scrubber solution of an alkali metal hydroxide to yield a metal hydroxide or metal oxide-containing precipitate and a soluble alkali metal halide.

The precipitate is then separated from the aqueous scrubber solution. The molten glass containing the treated waste material is removed from the bath as a waste glass. The process of the invention can be used to treat all types of waste material including radioactive wastes.

The process is particularly suited for separating halogens from halogen-containing wastes. A process is described for treating a halogen-containing waste material.

That the allowable project costs do not include a costs Treatment for hydrazine-containing waste water solution. The treatment for waste solutions containing hydrazine is presented. The invention attempts oxidation and decomposition of hydrazine in waste water in a simple and effective processing. The method adds activated charcoal to waste solutions containing hydrazine while maintaining a pH value higher than 8, and adding iron salts if necessary.

Then, the solution is aerated. Method for aqueous radioactive waste treatment. More than Risk management in waste water treatment. With the continuous restructuring of the water market due to liberalisation, privatisation and internationalisation processes, the requirements on waste water disposal companies have grown.

Increasing competition requires a target-oriented and clearly structured procedure. At the same time it is necessary to meet the environment-relevant legal requirements and to design the processes to be environment-oriented. The implementation of risk management and the integration of such a management instrument in an existing system in addition to the use of modern technologies and procedures can help to make the operation of the waste water treatment safer and consequently strengthen market position.

To achieve an identification of the risks as complete as possible, a subdivision of the kind of risks e. One possibility to assess risks is the portfolio method which offers clear representation. It allows a division of the risks into classes showing which areas need handling. The determination of the appropriate measures to handle a risk e. Different strategies can be applied here. On the one hand, the cause-oriented strategy, aiming at preventive measures which aim to reduce the probability of occurrence of a risk e.

On the other hand, the effect-oriented strategy, aiming to minimise the level of damage in case of an undesired occurrence e. Climate impact analysis of waste treatment scenarios--thermal treatment of commercial and pretreated waste versus landfilling in Austria. A major challenge for modern waste management lies in a smart integration of waste -to-energy installations in local energy systems in such a way that the energy efficiency of the waste -to-energy plant is optimized and that the energy contained in the waste is, therefore, optimally utilized.

The extent of integration of thermal waste treatment processes into regular energy supply systems plays a major role with regard to climate control. In this research, the specific waste management situation looked at scenarios aiming at maximizing the energy recovery from waste i. Comparing dedicated waste -to-energy-systems based on the combined heat and power CHP process with concepts based on sole electricity production, the energy efficiency proves to be crucial with regard to climate control.

This underlines the importance of choosing appropriate sites for waste -to-energy-plants. This research was looking at the effect with regard to the climate impact of various waste management scenarios that could be applied alternatively by a private waste management company in Austria.

The research is, therefore, based on a specific set of data for the waste streams looked at waste characteristics, logistics needed, etc. Furthermore, the investigated scenarios have been defined based on the actual available alternatives with regard to the usage of treatment plants for this specific company.

Hazardous waste treatment for spent pot liner. The spent pot liner is the largest solid waste produced by the electrolytic aluminum industry, composed of a series of substances that accumulate in the containers with reduced aluminum during the process of bauxite purification and refining. More and more spent pot liner is accumulated and needs to be dealt with. This paper discusses the composition and harm of solid waste.

This paper expounds the comprehensive utilization value and disposition of the waste pot liner. During NPP operation, several waste streams are generated, caused by different technical and physical processes. Besides others, liquid waste represents one of the major types of waste. Depending on national regulation for storage and disposal of radioactive waste , solidification can be one specific requirement.

To accommodate the global request for waste treatment systems Westinghouse developed several specific treatment processes for the different types of waste. In the period of to Westinghouse awarded several contracts for the design and delivery of waste treatment systems related to the latest CPR nuclear power plants. This plant already passed the hot functioning tests successfully in June and is now ready and released for regular operation.

The 'Follow on plants' are designed to package three 'typical' kind of radioactive waste : evaporator concentrates, spent resins and filter cartridges. The purpose of this paper is to provide an overview on the Westinghouse experience to design and execution of cementation facilities. Hydrometallurgical experiments are generally required to assess the appropriate treatment process before the establishment of the industrial recovery process for waste battery materials.

The effects of acid systems and oxidants in metal leaching were studied. The comprehensive leaching effects of the citric acid were superior to the sulfuric acid. The potassium permanganate inhibits the dissolution of metals. Thermodynamic calculations showed that metals precipitate more easily in sulfuric acid system than in citric acid system.

Crude manganese carbonate and a cobalt-nickel enriched liquid were obtained by selective precipitation in raffinate using an ammonium bicarbonate solution. The cobalt-nickel-copper enriched liquid was finally obtained. Studies have been conducted with a rotating biological contractor RBC to evaluate the treatability of leachates from the Stringfellow and New Lyme hazardous waste sites. The leachates were transported from the waste sites to Cincinnati at the United States Environmental Protect Detection, composition and treatment of volatile organic compounds from waste treatment plants.

Environmental policies at the European and global level support the diversion of wastes from landfills for their treatment in different facilities. Organic waste is mainly treated or valorized through composting, anaerobic digestion or a combination of both treatments. Thus, there are an increasing number of waste treatment plants using this type of biological treatment. During waste handling and biological decomposition steps a number of gaseous compounds are generated or removed from the organic matrix and emitted.

Many of these compounds are also sources of odor nuisance. In fact, odors are the main source of complaints and social impacts of any waste treatment plant. This work presents a summary of the main types of VOC emitted in organic waste treatment facilities and the methods used to detect and quantify these compounds, together with the treatment methods applied to gaseous emissions commonly used in composting and anaerobic digestion facilities.

Over the past fewyears, it has become increasinsly evident that land disposal of hazardous wastes is at least only a temporary solution for much of the wastes present at Superfund sites. The need for more Iong-term, permanent " treatment solutions as alternatives to land disposal Prospects of effective microorganisms technology in wastes treatment in Egypt. Sludge dewatering and treatment may cost as much as the wastewater treatment. Usually large proportion of the pollutants in wastewater is organic.

They are attacked by saprophytic microorganisms, i. Activity of organisms causes decomposition of organic matter and destroys them, where the bacteria convert the organic matter or other constituents in the wastewater to new cells, water, gases and other products.

These demolition wastes are characterized as heterogeneous mixtures of building materials that are usually contaminated with chemicals and dirt. That is equivalent to one third of the total daily municipal solid wastes generated per day in Egypt. The zabbaliin have since expanded their activities and now take the waste they collect back to their garbage villages where it is sorted into recyclable components: paper, plastics, rags, glass, metal and food.

The food waste is fed to pigs and the other items are sold to recycling centers. This paper summarizes the wastewater and solid wastes management in Egypt now and future. Revision 1. This section provides a description of the Hanford Site, identifies the proposed method of Area Waste Acid Treatment System WATS closure, and briefly summarizes the contents of each chapter of this plan.

A bio-hybrid anaerobic treatment of papaya processing wastes. Hybrid anaerobic treatment of papaya processing wastes is technically feasible. Elimination of post-handling and treatment of digested effluent can also be achieved. The system is more suitable for those processing plants with a waste amount of more than 3, metric tons per year.

Audits of hazardous waste TSDFs let generators sleep easy. This investigation must include an environmental and a financial audit. Simple audits may be performed by the hazardous waste generator, while more thorough ones such as those performed for groups of generators are more likely to be conducted by environmental consultants familiar with treatment , storage, and disposal techniques and the regulatory framework that guides them.

Development and testing of a wet oxidation waste processing system. The wet oxidation process is considered as a potential treatment method for wastes aboard manned spacecraft for these reasons: 1 Fecal and urine wastes are processed to sterile water and CO2 gas. However, the water requires post- treatment to remove salts and odor; 2 the residual ash is negligible in quantity, sterile and easily collected; and 3 the product CO2 gas can be processed through a reduction step to aid in material balance if needed.

Reaction of waste materials with oxygen at elevated temperature and pressure also produces some nitrous oxide, as well as trace amounts of a few other gases. The Environmental Protection Agency EPA has declared that vitrification is the "best demonstrated available technology" for high- level radioactive wastes HLW Federal Register and has produced a handbook of vitriilcation technologies for treatment of hazardous and radioactive waste US EPA, The goal of this study is to optimize the composition of glass for EVB waste at LANL, and present the basic techniques and tools for developing optimized glass compositions for other Pu-bearing materials in the complex.

This report outlines an approach for glass formulation with fixed property restrictions, using glass property-composition databases. This approach is applicable to waste glass formulation for many variable waste streams and vitrification technologies.. Also reported are the preliminary property data for simulated evaporator bottom glasses, including glass viscosity and glass leach resistance using the Toxicity Characteristic Leaching Procedure TCLP.

These activities generate radioactive liquid waste that must be handled in a manner to ensure protection of workers, the public, and the environment. The facility was designed at a time when environmental requirements, as well as more effective treatment technologies, were not inherent in engineering design criteria. The evolution of engineering design criteria has resulted in the older technology becoming less effective in treating radioactive liquid wastestreams in accordance with current National Pollutant Discharge Elimination System NPDES and Department of Energy DOE regulatory requirements.

This EID addresses the proposed action and alternatives for meeting the purpose and need for agency action. In addition, another problem was the illegal discharge of septic sewage collected from homes into rivers or on land. The nonoperational The discharge of raw. Destructive treatment of waste gas by catalytic afterburning and adsorption. Because of the considerable energy costs involved in the use of catalytic afterburning to clean up waste gases, an alternative method is suggested: adsorption with the use of low-cost adsorbents that are regenerated by destruction of the substances that has been taken up.

Activated semicoke ASK is proposed as an adsorbent and tested. On the basis of the results, ASK is recommended for the treatment of waste gases to remove oxygen-containing, sulfurcontaining, and tarry compounds. A facility may have one or more outfalls dischargers. The location represents the facility or operating plant.

Information provided in this closure plan is current as of April The long- awaited showdown between Blackboard Inc. The presidents of both companies, flanked by teams of lawyers, listened intently as their lawyers described how young…. Astronaut Michael Lopez-Alegria is looking on in background. Waste Water Management and Infectious Disease. The ability of various treatment processes, such as oxidation ponds, chemical coagulation and filtration, and the soil mantle, to remove the agents of infectious disease found in waste water is discussed.

The literature concerning the efficiency of removal of these organisms by various treatment processes is reviewed. The use of fly larvae for organic waste treatment. The idea of using fly larvae for processing of organic waste was proposed almost years ago.

Since then, numerous laboratory studies have shown that several fly species are well suited for biodegradation of organic waste , with the house fly Musca domestica L. House fly larvae develop well in manure of animals fed a mixed diet, while black soldier fly larvae accept a greater variety of decaying organic matter. Blow fly and flesh fly maggots are better suited for biodegradation of meat processing waste. The larvae of these insects have been successfully used to reduce mass of animal manure, fecal sludge, municipal waste , food scrapes, restaurant and market waste , as well as plant residues left after oil extraction.

Higher yields of larvae are produced on nutrient-rich wastes meat processing waste , food waste than on manure or plant residues. Larvae may be used as animal feed or for production of secondary products biodiesel, biologically active substances. Waste residue becomes valuable fertilizer. During biodegradation the temperature of the substrate rises, pH changes from neutral to alkaline, ammonia release increases, and moisture decreases.

Microbial load of some pathogens can be substantially reduced. Both larvae and digested residue may require further treatment to eliminate pathogens. Facilities utilizing natural fly populations, as well as pilot and full-scale plants with laboratory-reared fly populations have been shown to be effective and economically feasible. The major obstacles associated with the production of fly larvae from organic waste on an industrial scale seem to be technological aspects of scaling-up the production capacity, insufficient knowledge of fly biology necessary to produce large amounts of eggs, and current legislation.

Technological innovations could greatly improve performance of the biodegradation facilities and. The artificial water cycle: emergy analysis of waste water treatment. The artificial water cycle can be divided into the phases of water capture from the environment, potabilisation, distribution, waste water collection, waste water treatment and discharge back into the environment.

The terminal phase of this cycle, from waste water collection to discharge into the environment, was assessed by emergy analysis. Emergy is the quantity of solar energy needed directly or indirectly to provide a product or energy flow in a given process. The emergy flow attributed to a process is therefore an index of the past and present environmental cost to support it. Six municipalities on the western side of the province of Bologna were analysed.

Waste water collection is managed by the municipal councils and treatment is carried out in plants managed by a service company. Waste water collection was analysed by compiling a mass balance of the sewer system serving the six municipalities, including construction materials and sand for laying the pipelines.

Emergy analysis of the water treatment plants was also carried out. The results show that the great quantity of emergy required to treat a gram of water is largely due to input of non renewable fossil fuels. As found in our previous analysis of the first part of the cycle, treatment is likewise characterised by high expenditure of non renewable resources, indicating a correlation with energy flows.

Radioactive waste management treatments : A selection for the Italian scenario. The increased attention for radioactive waste management is one of the most peculiar aspects of the nuclear sector considering both reactors and not power sources. The aim of this paper is to present the state-of-art of treatments for radioactive waste management all over the world in order to derive guidelines for the radioactive waste management in the Italian scenario.

Starting with an overview on the international situation, it analyses the different sources, amounts, treatments , social and economic impacts looking at countries with different industrial backgrounds, energetic policies, geography and population. In particular, a double scenario is discussed to be considered in case of few quantities of nuclear waste : the use of regional, centralized, off site processing facilities, which accept waste from many nuclear plants, and the use of mobile systems, which can be transported among multiple nuclear sites for processing campaigns.

At the end the treatments suitable for the Italian scenario are presented providing simplified work-flows and guidelines. Investigations on the recycling of oyster shells and bone waste treatment using the plasma pyrolysis technique are presented in this paper. A arc based plasma torch operated at 25 kW was employed for the experiments.

Fresh oyster shells were recycled using the plasma torch to convert them to a useful product such as CaO. Bone waste was treated to remove the infectious organic part and to vitrify the inorganic part. The time required for treatment in both cases was significantly short. Significant reduction in the weight of the samples was observed in both cases. This study attempted to ascertain the economic viability of aquaculture as an alternative to conventional waste water treatment systems for small municipalities in the Southwestern region of the United States.

Economic evaluation of radiation processing in urban solid wastes treatment. During the last few years, quite a number of studies have been done, or are still in course, on disinfection of urban liquid wastes by means of ionizing radiations.

The experience gained by SANDIA pilot plant of irradiation on dried sewage sludge, together with the recently presented conceptual design of another plant handling granular solids, characterized by high efficiency and simple running, have shown the possibility of extending this process to the treatment of urban solid wastes.

As a matter of fact, the problems connected to the pathogenic aspects of sludge handling are often similar to those met during the disposal of urban solid wastes. This is even more so in the case of their reuse in agriculture and zootechny. The present paper introduces the results of an analysis carried out in order to evaluate the economical advantage of inserting irradiation treatment in some process scheme for management of urban solid wastes.

Taking as an example a comprehensive pattern of urban solid wastes management which has been analysed and estimated economically in previous works, we first evaluated the extra capital and operational costs due to the irradiation and then analysed economical justification, taking into account the increasing commercial value of the by-products.

Quality of life and coping in patients awaiting heart transplantation. The psychosocial adaptation of patients awaiting heart transplantation has not been defined. Unlike previously reported findings with patients after transplantation, those awaiting transplantation report moderate dissatisfaction with quality of life.

Patients report physical symptoms, functional disabilities, sexual dysfunction, and psychological distress. High levels of coping also were recorded. Having a positive attitude and seeking social support were the most common coping strategies, whereas confrontation, acceptance, and escapism were relatively uncommon.

In conclusion, patients awaiting heart transplantation, although dissatisfied with quality of life, maintain positive psychological and social adjustment. The treatment and disposal Waste battery treatment options: comparing their environmental performance. Waste consumer batteries are recycled using different routes based on hydrometallurgical and pyrometallurgical processes. Two hydrometallurgical and two pyrometallurgical treatment scenarios are compared starting from an average composition of Belgian waste batteries.

The environmental performance is compared using life cycle analysis LCA. The recycling rate is studied through mass balance calculation. Each treatment scenario results in a specific recycling rate. The environmental impact and benefits also vary between the treatment options. There is no such thing as a typical hydrometallurgical or pyrometallurgical treatment. When applying a hydrometallurgical treatment scenario, the focus lies on zinc and iron recycling.

When allowing manganese recycling, the energy demand of the hydrometallurgical process increases considerably. Both pyrometallurgical options recycle zinc, iron and manganese. According to the LCA, none of the treatment scenarios performs generally better or worse than the others. Each option has specific advantages and disadvantages. Based on metal recycling alone, the mass balances show that the target is difficult to obtain.

For the requirements previously found in this section and for treatment Examination of Treatment Methods for Cyanide Wastes.

Radiological Monitoring of Waste Treatment Plant.

Scheduled waste in West Malaysia is handled by Concession Company and is stored and then is incinerated. It is known that incineration process may result in naturally occurring radioactive materials NORM to be concentrated. In this study we have measured three samples consist of by-product from the operation process such as slag, filter cake and fly ash. Other various environmental media such as air, surface water, groundwater and soil within and around the plant have also been analysed for their radioactivity levels.

The concentration of Ra, Ac and K in slag are 0. The concentration in fly ash is 0. For filter cake, the concentration is 0. The external radiation level ranges from 0. The concentration level of radon and thoron progeny varies from 0. For soil samples, the activity ranges from 0. While activity in water, except for a trace of K, it is non-detectable.

Chlortetracycline and the macrolide tylosin were identified as commonly used antimicrobials for growth promotion and prophylaxis in swine production. Resistance to these antimicrobials was measured throughout the waste treatment processes at five swine farms by culture-based and molecular methods. Conventional farm samples had the highest levels of resistance with both culture-based and molecular methods and had similar levels of resistance despite differences in antimicrobial usage.

The levels of resistance in organic farm samples, where no antimicrobials were used, were very low by a culture-based method targeting fecal streptococci. All of the feed samples tested, including those from the organic farm, contained tetracycline resistance genes. Generally, the same tetracycline resistance genes and frequency of detection were found in the manure and lagoon samples for each commercial farm.

The levels of tetracycline and MLSB resistance remained high throughout the waste treatment systems, suggesting that the potential impact of land application of treated wastes and waste treatment by-products on environmental levels of resistance should be investigated further.

Crystal accumulation in the Hanford Waste Treatment Plant high level waste melter: Summary of experiments. A full-scale, transparent mock-up of the Hanford Tank Waste Treatment and Immobilization Project High Level Waste glass melter riser and pour spout has been constructed to allow for testing with visual feedback of particle settling, accumulation, and resuspension when operating with a controlled fraction of crystals in the glass melt.

Room temperature operation with silicone oil and magnetite particles simulating molten glass and spinel crystals, respectively, allows for direct observation of flow patterns and settling patterns. The fluid and particle mixture is recycled within the system for each test. Waste Water Treatment Apparatus and Methods. An improved draft tube spout fluid bed DTSFB mixing, handling, conveying, and treating apparatus and systems, and methods for operating are provided.

In addition to conveying apparatus, a collection and separation apparatus adapted to receive the conveyed particulate material is also provided. The disclosed apparatus may be used to mix particulate material, for example, mortar; react fluids with particulate material; coat particulate material, or simply convey particulate material. A raw sewage treatment process is disclosed in which substantially all the non-dissolved matter, suspended in the sewage water is first separated from the water, in which at least organic matter remains dissolved.

The activated carbon and ash material adsorbs the organic matter dissolved in the water and is thereafter supplied in a counter flow direction and combined with the incoming raw sewage to at least facilitate the separation of the non-dissolved settleable materials from the sewage water.

Carbon and ash material together with the non-dissolved matter which was separated from the sewage water are pyrolyzed to form the activated carbon and ash material. Industrial waste treatment and application in rubber production. The paper provides for the relevance of various industrial waste treatment and application, as well as their secondary commercialization.

It considers treatment of secondary polymer materials turning to additives applied in rubber production, in particular, in production of conveyor and V-type belts used in mechanical engineering. It is found that oligomers obtained from petroleum by-products can be used as an impregnating compound for fiber materials. Such adhesive treatment prior to introduction of impregnating compounds into elastomeric materials improves adhesion and complements performance of obtained composites.

Technoeconomic aspects of alternative municipal solid wastes treatment methods. This paper considers selected treatment technologies for comingled domestic and similar wastes and provides technoeconomic data and information, useful for the development of strategic management plans. For this purpose, treatment technologies of interest are reviewed and representative flow diagrams, along with material and energy balances, are presented for the typical composition of wastes in Greece; possible difficulties in the use of treatment products, along with their management implications, are discussed, and; cost functions are developed, allowing assessment of the initial capital investment and annual operating costs.

Copyright Elsevier Ltd. Using phytoremediation technologies to upgrade waste water treatment in Europe. One of the burning problems of our industrial society is the high consumption of water and the high demand for clean drinking water. Numerous approaches have been taken to reduce water consumption, but in the long run it seems only possible to recycle waste water into high quality water.

It seems timely to discuss alternative water remediation technologies that are fit for industrial as well as less developed countries to ensure a high quality of drinking water throughout Europe. The present paper discusses a range of phytoremediation technologies to be applied in a modular approach to integrate and improve the performance of existing wastewater treatment , especially towards the emerging micro pollutants, i. This topic is of global relevance for the EU.

Existing technologies for waste water treatment do not sufficiently address increasing pollution situation, especially with the growing use of organic pollutants in the private household and health sector. Although some crude chemical approaches exist, such as advanced oxidation steps, most waste water treatment plants will not be able to adopt them.

The same is true for membrane technologies. Incredible progress has been made during recent years, thus providing us with membranes of longevity and stability and, at the same time, high filtration capacity. However, these systems are expensive and delicate in operation, so that the majority of communities will not be able to afford them. Combinations of different phytoremediation technologies seem to be most promising to solve this burning problem.

To quantify the occurrence and the distribution of micropollutants, to evaluate their effects, and to prevent them from passing through wastewater collection and treatment systems into rivers, lakes and ground water bodies represents an urgent task for applied environmental sciences in the coming years.

Public acceptance of green technologies is generally higher than that of. Catalytic dry reforming of waste plastics from different waste treatment plants for production of synthesis gases. Catalytic dry reforming of mixed waste plastics, from a range of different municipal, commercial and industrial sources, were processed in a two-stage fixed bed reactor.

Overall, the catalytic-dry reforming of waste plastics from various waste treatment plants showed great potential towards the production of synthesis gases. The preferred alternative s will process projected future ETF influents to produce a solid waste acceptable for final disposal on the Hanford Site.

The evaluation process includes identification of available modifications to the current ETF process, screens those modifications for technical viability, evaluates the technically viable alternatives, and provides conclusions and recommendations based on that evaluation.

Greenhouse gas emissions of different waste treatment options for sector-specific commercial and industrial waste in Germany. The sensitivity analysis of the different scenarios for this paper shows that the efficiency and the substitution factor of energy have a relevant influence on the result. Estimation of marginal costs at existing waste treatment facilities. To avoid misleading conclusions, economic assessment of alternative SWM solutions should not only consider potential costs associated with alternative treatment but also include marginal costs associated with existing facilities.

Patients awaiting lung transplantation are at risk of negative emotional and physical experiences. How do they talk about emotions? Semi-structured interviews were performed 15 patients.

Categorical analysis focusing on emotion-related descriptions was organized into positive—negative—neutral descriptions: for primary and secondary emotions, evaluation processes, coping strategies, personal characteristics, emotion descriptions associated with physical states, and contexts were listed.

Patients develop different strategies to maintain positive identity and attitude, while preserving significant others from extra emotional load. Categorical analysis focusing on emotion-related descriptions was organized into positive-negative-neutral descriptions: for primary and secondary emotions, evaluation processes, coping strategies, personal characteristics, emotion descriptions associated with physical states, and contexts were listed.

Results are discussed within various theoretical and research backgrounds, in emphasizing their importance in the definition of emotional support starting from the patient's perspective. A nursing diagnosis approach to the patient awaiting cardiac transplantation.

The most common reason to perform cardiac transplantation is dilated cardiomyopathy. Alterations in cardiac output secondary to decreased contractility and increased preload and afterload will, over time, lead to progressive deterioration of the patient with this type of end-stage cardiac disease.

Heart transplantation is now an accepted therapy for these patients. This article focused on the patient in the period awaiting cardiac transplantation. Five pertinent nursing diagnoses were identified and discussed. A case study approach was utilized to highlight patient problems and nursing interventions.

Characterization of the solid low level mixed waste inventory for the solid waste thermal treatment activity - III. The existing thermally treatable, radioactive mixed waste inventory is characterized to support implementation of the commercial, thermal treatment contract.

The existing thermally treatable waste inventory has been identified using a decision matrix developed by Josephson et al. Similar to earlier waste characterization reports Place and , hazardous materials, radionuclides, physical properties, and waste container data are statistically analyzed.

In addition, the waste inventory data is analyzed to correlate waste constituent data that are important to the implementation of the commercial thermal treatment contract for obtaining permits and for process design. A qualitative description of the thermally treatable mixed waste inventory is also provided. Genetic engineering approach to toxic waste management: case study for organophosphate waste treatment. Currently, there has been limited use of genetic engineering for waste treatment.

In this work, we are developing a procedure for the in situ treatment of toxic organophosphate wastes using the enzyme parathion hydrolase. Since this strategy is based on the use of an enzyme and not viable microorganisms, recombinant DNA technology could be used without the problems associated with releasing genetically altered microorganisms into the environment.

The gene coding for parathion hydrolase was cloned into a Streptomyces lividans, and this transformed bacterium was observed to express and excrete this enzyme. Subsequently, fermentation conditions were developed to enhance enzyme production, and this fermentation was scaled-up to the pilot scale.

The cell-free culture fluid i. Treatment of waste printed wire boards in electronic waste for safe disposal. The printed wire boards PWBs in electronic waste E- waste have been found to contain large amounts of toxic substances. Studies have concluded that the waste PWBs are hazardous wastes because they fails the toxicity characteristic leaching procedure TCLP test with high level of lead Pb leaching out.

In this study, two treatment methods - high-pressure compaction and cement solidification - were explored for rendering the PWBs into non-hazardous forms so that they may be safely disposed or used. The high-pressure compaction method could turn the PWBs into high-density compacts with significant volume reduction, but the impact resistance of the compacts was too low to keep them intact in the environment for a long run.

In contrast, the cement solidification could turn the PWBs into strong monoliths with high impact resistance and relatively high compressive strength. The leaching of the toxic heavy metal Pb from the solidified samples was evaluated by both a dynamic leaching test and the TCLP test. The dynamic leaching results revealed that Pb could be effectively confined in the solidified products under very harsh environmental conditions.

It was concluded that the cement solidification is an effective way to render the waste PWBs into environmentally benign forms so that they can be disposed of as ordinary solid wastes or beneficially used in the place of concrete in some applications. Fate of metals contained in waste electrical and electronic equipment in a municipal waste treatment process.

Oguchi, Masahiro, E-mail: oguchi. Black-Right-Pointing-Pointer Most metals were mainly distributed to the small-grain fraction. Black-Right-Pointing-Pointer Pre-sorting of small digital products reduces metals to be landfilled at some level. This study investigated the distribution ratios and substance flows of 55 metals contained in WEEE during municipal waste treatment using shredding and separation techniques at a Japanese municipal waste treatment plant.

The results revealed that more than half of Cu and most of Al contained in WEEE end up in landfills or dissipate under the current municipal waste treatment system. Most kinds of metals were concentrated several fold in the small-grain fraction through the process and therefore the small-grain fraction may be a next target for recovery of metals in terms of both metal content and amount. Separate collection and pre-sorting of small digital products can work as effective way for reducing precious metals and less common metals to be landfilled to some extent; however, much of the total masses of those metals would still end up in landfills and it is also important to consider how to recover and utilize metals contained in other WEEE such as.

The layout considers the major treatment processes of the HDB as well as regulatory and legal requirements. The main function of the system is the data management of all processes related to treatment , transfer and storage of radioactive material within HDB. Analytical data from the laboratory and non destructive assay systems, that describe the chemical and radiological properties of residues, production batches, interim products as well as final waste products, can be linked to the respective dataset for documentation and declaration.

The system enables the operator to trace the radioactive material through processing and storage. Information on the actual sta-tus of the material as well as radiological data and storage position can be gained immediately on request. A variety of programs accessed to the database allow the generation of individual reports on periodic or special request.

Short mechanical biological treatment of municipal solid waste allows landfill impact reduction saving waste energy content. The aim of this work was to evaluate the effects of full scale MBT process 28 d in removing inhibition condition for successive biogas ABP production in landfill and in reducing total waste impact. Results showed that untreated landfilled- waste gave a total ABP reduction that was null. Therefore short MBT allowed reducing landfill impact, preserving energy content ABP to be produced successively by bioreactor technology since pre- treatment avoided process inhibition because of partial waste biostabilization.

Treatment of waste water by coagulation and flocculation using biomaterials. The present study deals with the determination of physical and chemical parameters in the treatment process of waste water by flocculation and coagulation processes using natural coagulants and assessing their feasibility for water treatment by comparing the performance with each other and with a synthetic coagulant.

Initial studies were done on the synthetic waste water to determine the optimal pH and dosage, the activity of natural coagulant, followed by the real effluent from tannery waste. The study reveals that the untreated tannery effluents can be treated with environmental confirmative naturally occurring coagulants.

Thermal plasma technology for the treatment of wastes : a critical review. This review describes the current status of waste treatment using thermal plasma technology. A comprehensive analysis of the available scientific and technical literature on waste plasma treatment is presented, including the treatment of a variety of hazardous wastes , such as residues from municipal solid waste incineration, slag and dust from steel production, asbestos-containing wastes , health care wastes and organic liquid wastes.

She suggested that tubers wear the bandanas around their necks during their ride on the river. Anyone who refuses to wear the bandana will be denied service. She said other social distancing measures will include limiting the number of passengers per bus to 15, even though the buses seat as many as 72 passengers.

But only last week, on May 9, there was little or no evidence that the tubers were paying attention to the CDC guidelines. They were clustered in groups, including a family with small. And it includes banning campfires, which Coil said may have a double benefit, not only reducing small fires but also minimizing the spread of COVID on campgrounds.

As far as what kind of role the stayat-home order will play in the wildfire season, Valliere said it is too early to tell. But Coil said that because many people are not working because of the shutdown, they could be more likely to engage in activities that could spark a fire, by taking their trailers out to the lake and dragging the chains on the road, for example.

Scottsdale Fire Deputy Chief Adam Hoster said the department plans to use social media and other technology to spread the message of fire prevention and to track fire activity. Swimming trunks, bikinis, tank tops and flip flops were way more popular than masks.

Nancy Barto, R-Phoenix. But House Republicans have a laundry list of issues they want addressed. That decision by the GOP to remain in session angered Rep. Arlando Teller, D-Chinle, who pointed out that the Navajo Nation has the highest per capita infection rate in the country. Minority Leader Charlene Fernandez, D-Yuma, chided colleagues for voting on changes in state oversight of college savings programs.

She said what her constituents need is food. But those additional benefits are set to disappear this summer. The divide between Republicans and Democrats over COVID was pointed up by the fact that only a handful of Republicans were wearing masks; all the Democrats had their faces covered. Diego Rodriguez, D-Phoenix. At the same time, though, there has been some finger pointing about what is taking so long to wrap up the session. Most of those directives are now gone.

One unanswered question is whether the votes taken Tuesday -- and those set for the rest of the week -- will actually result in changes in the law. Technically speaking, while the Senate voted to say it is finished, it has not gone home. But Fann also noted that being in recess leaves the door open for dealing with a few more issues if needed. And one of those she personally favors is a bill set for House debate to make it harder for people who contract COVID to sue businesses.

In lifting his stay-at-home order and allowing restaurants to open May 11, Gov. Doug Ducey releases a list of protocols restaurants should follow to keep hand-to-hand contact at a minimum.

Those protocols include screening staff for COVID symptoms at the start of every shift, using disposable menus and banning shared condiment. It looks like there may be at least two Democrats on the Arizona Corporation Commission for the next two years unless the Arizona Republican Party can find someone with high name ID. The justices, in a brief order, refused her request to reconsider an earlier finding that she did not submit enough valid signatures to qualify.

That order comes just days after the court reached a similar conclusion for incumbent Republican Boyd Dunn, ending his bid for reelection. What makes all that significant is there are now just two Republicans left on the ballot: incumbent Lea Marquez Peterson who was appointed to her post last year by Gov. Doug Ducey, and Eric Sloan.

And there are three positions on the five-member panel up for grabs. By contrast, all three Democrat contenders appear to be cleared to run: Bill Mundell, who actually served for a decade on the commission as a Republican until ; Anna Tovar, a. Zach Henry. The best option is to find someone to run as a write-in candidate for the Aug. And anyone can try to get nominated by this route by submitting his or her name and financial disclosure statement by June And that puts the party in the position of finding someone with whose names is sufficiently familiar so that party faithful will remember it while filling out early ballots at home or writing it in when they go to the polls.

Nick Myers was previously disqualified. And state Sen. David Farnsworth, R-Mesa, who had hoped to move to the commission, withdrew his name from consideration after a challenge was mounted to his petition signatures. Two members of the commission are not up for reelection this year: Democrat Sandra Kennedy and Republican Justin Olson. Wright said Pedal Haus is trying to follow all the recommended guidelines and is continuing to look for new ways to limit the risk of exposing customers to the COVID virus.

In addition to creating the CSO role, Pedal Haus has moved around its dining area to add more space between customers, removed some barstools and added hand-sanitizer stations. Pedal Haus has also created its own custom-made face masks, Wright added, which must be worn by all staff during their shift.

Pedal Haus opened its first location in Tempe a few years ago and quickly became known for its unique selection of original beers. The business has won numerous dining awards, been routinely covered in the local press, and was just starting to spread its reach across the East Valley.

Its Chandler location had only been open a couple weeks before the pandemic hit in March and businesses were ordered closed. The Chandler restaurant was shut down for almost two months, Wright said, aside from the take-out service they offered for a couple weeks. Pedal Haus had been in the midst of planning the opening of another location in downtown Phoenix before COVID, but that project has been delayed for the time being.

The upcoming summer months will probably be rough, Wright said, yet Pedal Haus is confident it can weather through this storm.

Restaurants were forced to transition to takeout and delivery, retail stores were closed, and all sporting events were suspended until further notice.

That suspension turned into a cancellation for universities and high schools back in March. Leagues across the East Valley and Ahwatukee quickly followed suit, canceling their seasons. However, the participation rate drops significantly at that level. Chandler National usually fields as.

George had hoped to make the All-Star team this summer and get the chance to win a state title and go further, perhaps even to Williamsport, Penn.

But much like it was for seniors in high school in their final season, the opportunity was unfortunately taken away. Everyone supported each other this year and had good sportsmanship. Both Gilbert American and Gilbert National joined as well.

To have this last year taken from them is difficult. For nearly three decades, Mike Erickson has presented local parents with a fun and safe option for their kids to go during the summer months. Even now, as the coronavirus pandemic has made individuals adapt to a new normal, Erickson plans to be there for parents as the state begins to loosen restrictions and parents begin to head back to work.

He attributes the consistent success every summer not only to the community that entrusts him with their children, but for the way his camp is run compared to others. They are all separated into smaller groups and participate in different activities. Most of the groups start the morning with a field trip to a local business.

Erickson expects Big Air Trampoline Park, an indoor facility opening nearby, to be a big hit for kids once able to safely attend. The groups go on fieldtrips to a local Peter Piper Pizza and movie theater. More activities from arts and crafts to indoor sports are then played until lunch. We are encouraging exercise, but we are also working to keep the kids safe and happy. Kids are allowed to interact with others, but they generally stay within their own small groups.

The camp typically runs until 4 p. From 9 to 11 a. We wanted to offer that same experience. Tucked In Tommy Bahama Shirt. Our hero settled for sighing and eye-rolling his way to a chair beneath the lobby flat screen, where, mask on, he commenced barking into his iPhone.

Costco discovered this a couple weeks ago, immediately after announcing a new policy requiring members and guests to wear a face covering when entering its warehouses. Soon after came the predictable backlash: Costco received a wave of support for not buckling to the threats and keeping its mask requirement in place. Expect many more such arguments to occur over the next few weeks, as our economy lurches back into motion, businesses begin reopening and hordes on both sides of this argument turn a simple.

You know what wearing a mask really means? And pretty much nothing else. You know what not wearing a mask means? Anymore, as we split ourselves into warring tribes, we seek to invest with massive meaning all sorts of small acts that we hold out as proof we belong to this or that club. Mask wearers hold themselves out to be more evolved than those who refuse to wear a mask. Members of Team Breathe Free or Die think of themselves as outlaw badasses, freedom fighters willing to sacrifice buying raw almonds and toilet paper in bulk at Costco in service to their cause.

The truth? Medical science in large part has come down on the side of wearing a mask while in public and in close proximity to others as a way of slowing the spread of COVID After all, as everyone knows, only idiots tuck in Hawaiian shirts. From an economic standpoint, Arizona has been, to borrow a phrase from Gov. The results: we ended with the third-highest year-over-year employment gain in the United States, according to the Bureau of Labor Statistics.

Exports also reached a record high last year and our state was projected to add an astounding , jobs by Our region celebrated some big economic development wins, with. We also heralded the growth and development of some the most creative entrepreneurial startups and small businesses imaginable. COVID has changed that trajectory, yet I believe our state and region will emerge from this crisis stronger than ever.

Restarting our economy is a critical factor in making this happen, but our approach to re-emerging from this crisis must be slow and steady. That is, we must balance the health and well-being of our citizens with the need to get back to work.

What I like most about his approach is that it leads with public health. After all, in a situation with so many unknowns, we. Enlisting ideas from business leaders also is a plus because who knows better than restaurant, retail and other owners who live and breathe their businesses every day how to modify their operations successfully?

On a broader level, our leaders are also forging ahead with important economic development, education enhancements and quality of life initiatives. Some cases in point: City and town officials have stepped up efforts to reignite small businesses. The Mesa City Council approved its largest master-planned development, which is projected to create 55, new jobs.

President Michael Crow and his team at the uber-innovative Arizona State University are charting a course to transform our economy by laying the foundation for what technology-enhanced businesses are going to be.

None of this work should come as a surprise. After all, in Arizona and the. PHX East Valley, our greatest asset is the ingenuity of our people who work together for a common goal.

We do have a few who need additional services, and I will be talking with the VA about how to accomplish this. We appreciate you all very much. A Chandler teacher is connecting virtually with students through fun, interactive videos he creates alongside his sixth-grade son. Hamlet Opazo has recited the morning announcements at Leman Academy of Excellence in Mesa since it opened in But when the coronavirus pandemic shifted in-person classes to online for the remainder of the school year, Opazo wanted to find a way to interact with students in a way that would keep them engaged.

On Wednesdays, he and his son, Phoenix, generally use Legos. Recently, he took students through a virtual time machine back to the s and showed them how to make a hulahoop out of PVC pipe to stay active. Each video covers a different subject, such as physical education and he.

Right: Hamlet Opazo plays a detective with his son Phoenix for one of his videos. Opazo typically films his videos the day before releasing them. But now, some take four to almost seven hours long from beginning to the point where I send them off. Kuwait, where he and his wife worked following his graduation from Grand Canyon University.

Hamlet, your jokes are kind of cheesy and corny. Opazo and Anita then went on to teach in North Africa for a year before returning to the U. He then began working at Leman Academy while Anita taught music at their Chandler home. He often hears positive feedback from other teachers or parents and students about his videos.

Many have told him his morning announcement video is something they look forward to on a daily basis and that the lessons have helped kids stay engaged. Each artist could bring their own idea for painting a box. Opazo said even children from out of state email him about an art technique they learned from one of his videos. The support from the Leman Academy community motivates him to continue putting a spin on morning announcements.

City officials say Enriquez's work on the wall along the Commonwealth Canal enriches pedestrians' experience as they walk along it. The back of the box depicts a cactus wren perched upon a jumble of prickly pear cactus. The entire downtown region is now home to more than 30 sculptures, murals and paintings that can be spotted along the Arizona Avenue corridor.

Some of these projects have come to fruition thanks to downtown business owners partnering with the city to help artists bring their designs to life in various spots surrounding City Hall. Contact Mary Babick at You can legally go catch a flick at your local theater. But they are willing to sell you popcorn, and even bring it out to the curb for you. The Department of Health Services has issued guidelines for how the theaters should operate, covering everything from seating to butter dispensers for popcorn.

These are being phrased as suggestions and recommendations, leaving a lot up to individual operators and, ultimately, to customers to see if they feel safe. Yes, Ducey has said that games can go on, albeit without fans. The latest news show team owners looking for a start in early July — assuming some arrangement can be reached with players.

The Dunnes are considering other types of events, too, such as concerts, karaoke nights and comedy shows. We were thinking of rolling out some really cool concerts where everyone turns on their speakers and they beam the show into the car.

We can make the shows interactive with Instagram, too. We can be creative as can be. The technology allows us to do so many things. This has been a blessing for Salt River Fields, our partner, and us. Despite the challenges it is facing, the company is bringing dance to the community—but in a different way.

Since March, it has been releasing videos showing the dancers in motion in their homes. For the first video, they did 1-minute recordings of themselves dancing on and over a chair. Many of the dancers have been performing by themselves, although of the dancers included her children in one of the videos. He has also been assisting with video editing. Scorpius artistic director Lisa Starry has encouraged dancers to take part in the videos so that they can still keep doing what they love.

She said members of the company have missed dancing and spending time with each other. There are also so many parts besides just rehearsing. We are all friends. We support each other. We talk. Starry hopes that the videos with bring some positivity during a difficult time. That includes its 20th anniversary showcase set for April. Starry said that community support has been important because of the uncertainty the dancers and the studio are facing. My studio had to close.

We are doing a fundraiser to just pay the bills for the next couple of months and help the dancers out, too. Scorpius dancer Angel Castro has been recording himself in performances as theaters and other venues remain dark.

AMC, the other big player in Arizona, did not immediately return calls seeking a schedule. The company is not listing any showtimes for the immediate future. Arizonans anxious to sit in the dark may have some options soon.

Look around our community. There you will find people who may appear different, but in reality, they are not because each of them is distinctive in his or her own way. Some may speak with an accent that makes it hard to understand and some wear clothing that seems bizarre. The truth is that while we may have different customs and traditions from the various areas of the country that was our home, we are all people who are now enjoying the fruits of our labors in an environment that gives us comfort and joy.

This is Sun Lakes. If we drive up and down Riggs Road, we will see edifices that have been erected for the purpose of gathering to offer thanksgiving to the One who gave. There are churches and a synagogue dedicated to the betterment of our society through our involvement in the many activities that offer connection.

While we may have different approaches to our understanding of God and how it is expressed, the one thing we all understand is that the path is not the important aspect of our connection to one another. The important part of our relationship deals with the destination.

The destination is the same for all of us: joining in acknowledging our obligation to honor the concept of Love and Faith and Harmony. How best to reach this destination? Joining our houses of worship so that we will always feel the inspiration of God who is there to receive us and listen to our prayers. As we enter our respective houses of worship we immediately are reminded of history, and tradition, and faith.

There is an unexplainable chill that runs through our veins because we feel a sense of reverence and peace. Generations past have felt the very same thing, but I wonder if the generation that follows will also receive this feeling of love. Now, more than ever, we have been reminded that while our houses of worship stand in all their grandeur, we could not enter for fear of a terrible scourge that may cause us all pain and sorrow.

Now, more than ever, we have to realize that not being able to express ourselves in various rituals and traditions gave us a feeling of emptiness. We were like lost sheep looking for. Now, more than ever, we need to reinforce our desire to ensure that these facilities remain available for all to enter and marvel at the symbols erected to remind us that we are not alone in trying to find meaning and purpose in our lives. Now, more than ever, we need to continue to strive for human decency.

Now, more than ever, we must remember that having faith includes faith in ourselves. We have the ability to overcome adversity in partnership with God. When the call goes out to support these havens of relief and fulfillment, we must answer with all that we are able. This is our obligation because most of all, these places of reverence teach us the most important lesson of all: That each of us has value. Voices seem to grow more and more strident.

Tensions escalate pain and frustration, which highlight differences in understanding and perspective. This gives way to anger, hostility and accusations. It happens in homes, in churches, in government and in society at large. It sometimes evolves into violence which tears apart and destroys individuals, relationships, families and organizations.

Two quotations from John Wesley, continue to ruminate in my mind,. I believe they can help us in the times in which we live. Though we cannot think alike, may we not love alike? May we not be of one heart, though we are not of one opinion? Without all doubt, we may. Herein all the children of God may unite, notwithstanding these smaller differences. These remaining as they are, they may forward one another in love and in good works.

May God grant us all to be agents and examples of peace and goodwill to each other. In both these statements I hear him calling us to remember our relationship with each other is more important than our beliefs.

Centralized waste treatment of industrial wastewater. Centralized waste treatment CWT for industrial wastewater is described in this book. With the CWT approach, industrial firms send their wastes to a common processing plant. The book addresses the engineering and business-related problems that are encountered by private CWT firms, local governments, and industry in creating sufficient CWT capacity to meet the growing demand for CWT services.

Waste treatment in silicon production operations. A battery of special burners, each adapted for the treatment of a particular range of waste material formed during the conversion of metallurgical grade silicon to high purity silane and silicon, is accompanied by a series arrangement of filters to recover fumed silica by-product and a scrubber to recover muriatic acid as another by-product.

All of the wastes are processed, during normal and plant upset waste load conditions, to produce useful by-products in an environmentally acceptable manner rather than waste materials having associated handling and disposal problems. Enhancement of waste activated sludge WAS anaerobic digestion by means of pre- and intermediate treatments.

Technical and economic analysis at a full-scale WWTP. Anaerobic digestion AD is the most commonly applied end- treatment for the excess of waste activated sludge WAS generated in biological wastewater treatment processes. The efficacy of different typologies of pre- treatments in liberating intra-cellular organic substances and make them more usable for AD was demonstrated in several studies. However, the production of new extracellular polymeric substances EPSs that occur during an AD process, due to microbial metabolism, self-protective reactions and cell lysis, partially neutralizes the benefit of pre- treatments.

The efficacy of post- and inter-stage treatments is currently under consideration to overcome the problems due to this unavoidable byproduct. This work compares three scenarios in which low-temperature treatments were applied to one sample of WAS and two samples of digestate with hydraulic retention times HRTs of 7 and 15 days. Batch mesophilic digestibility tests demonstrated that intermediate treatments were effective in making the residual organic substance of a 7-day digestate usable for a second-stage AD process.

The results of the digestibility tests were used for a tecno-economic assessment of pre- and intermediate lysis treatments in a full scale wastewater treatment plant WWTP, 2,, p. It was demonstrated that the introduction of thermal or hybrid pre- treatments could increase the revenues from the. Evaluation of anaerobic digestion processes for short sludge-age waste activated sludge combined with anammox treatment of digestate liquor. The need to reduce energy input and enhance energy recovery from wastewater is driving renewed interest in high-rate activated sludge treatment i.

This process generates short SRT activated sludge stream, which should be highly degradable. However, the evaluation of anaerobic digestion of short SRT sludge has been limited. This paper assesses anaerobic digestion of short SRT sludge digestion derived from meat processing wastewater under thermophilic and mesophilic conditions.

The digestion effluents from the thermophilic day HRT and mesophilic systems were stable, as assessed by residual methane potentials. Solid Waste Activity Packet for Teachers.

Destructive treatment of waste gas by catalytic afterburning and adsorption. Because of the considerable energy costs involved in the use of catalytic afterburning to clean up waste gases, an alternative method is suggested: adsorption with the use of low-cost adsorbents that are regenerated by destruction of the substances that has been taken up. Activated semicoke ASK is proposed as an adsorbent and tested. On the basis of the results, ASK is recommended for the treatment of waste gases to remove oxygen-containing, sulfurcontaining, and tarry compounds.

Utilization of the wastes of vital activity. Gusarov, B. The recycling of wastes from the biological complex for use in life-support systems is discussed. Topics include laboratory equipment, heat treatment of waste materials, mineralization of waste products, methods for production of ammonium hydroxide and nitric acid, the extraction of sodium chloride from mineralized products, and the recovery of nutrient substances for plants from urine.

This study is aimed at evaluating the existing waste management approaches for nuclear fuel cycle facilities in comparison to the objectives of implementing an advanced fuel cycle in the U. The tenets of the IWMS are equally valid to the current waste management study.

However, the flowsheet details have changed significantly from those considered under GNEP. This study updates the information found in the WTBS, summarizes the results of more recent technology development efforts, and describes waste management approaches as they apply to a representative full recycle reprocessing flowsheet. Many of the waste management technologies discussed also apply to other potential flowsheets that involve reprocessing. These applications are occasionally discussed where the data are more readily available.

The report summarizes the waste arising from aqueous reprocessing of a typical light-water reactor LWR fuel to separate actinides for use in fabricating metal sodium fast reactor SFR fuel and from electrochemical reprocessing of the metal SFR fuel to separate actinides for recycle back into the SFR in the form of metal fuel.

The primary streams considered and the recommended waste forms include; Tritium in low-water cement in high integrity containers HICs ; Iodine As a reference case, a glass composite material GCM formed by the encapsulation of the silver Mordenite AgZ getter material in a low-temperature glass is assumed. A number of alternatives with distinct advantages are also considered including a fused silica.

These activities generate radioactive liquid waste that must be handled in a manner to ensure protection of workers, the public, and the environment. The facility was designed at a time when environmental requirements, as well as more effective treatment technologies, were not inherent in engineering design criteria. The evolution of engineering design criteria has resulted in the older technology becoming less effective in treating radioactive liquid wastestreams in accordance with current National Pollutant Discharge Elimination System NPDES and Department of Energy DOE regulatory requirements.

This EID addresses the proposed action and alternatives for meeting the purpose and need for agency action. Alkyl polyglucose enhancing propionic acid enriched short-chain fatty acids production during anaerobic treatment of waste activated sludge and mechanisms. Not only the production of SCFAs, especially propionic acid, was significantly improved by APG, but also the feasible operation time was shortened. The SCFAs yield at 0. Mechanism investigation showed that during anaerobic treatment of WAS in the presence of APG both the solubilization and hydrolysis were accelerated and the acidification was enhanced, while the methanogenesis was inhibited.

The abundance of microorganisms responsible for organic compounds hydrolysis and SCFAs production was also observed to be greatly enhanced with APG via high-throughput pyrosequencing analysis. Economic and environmental optimization of waste treatment. As part of the optimization, the model identifies the most attractive waste management options.

A simple illustrative case is analysed, covering alternative treatments of one tonne of residual household waste : incineration of the full amount or sorting out organic waste for biogas production for either combined heat and power generation or as fuel in vehicles.

The case study illustrates that the optimal solution depends on the objective and assumptions regarding the background system — illustrated with different assumptions regarding displaced electricity production. The article shows that it is feasible to combine LCA methodology with optimization.

Furthermore, it highlights the need for including the integrated waste and energy system into the model. Free nitrous acid pre- treatment of waste activated sludge enhances volatile solids destruction and improves sludge dewaterability in continuous anaerobic digestion. This suggests that FNA pre- treatment would enhance the destruction of volatile solids VS in an anaerobic sludge digester, and reduce overall sludge disposal costs, provided that the dewaterability of the digested sludge is not negatively affected.

This study experimentally evaluates the impact of FNA pre- treatment on the VS destruction in anaerobic sludge digestion and on the dewaterability of digested sludge, using continuously operated bench-scale anaerobic digesters. Biochemical methane potential tests indicated that the final digestate stability was also improved with a lower potential from FNA treated digestate.

Further, a 2. This results in significantly reduced costs as assessed by economic analysis. Changes in waste stabilisation pond performance resulting from the retrofit of activated sludge treatment upstream: part I--water quality issues. This paper describes changes in effluent quality occurring before and after an upgrade to the Bolivar Wastewater Treatment Plant in South Australia. Trickling filters TF were replaced with an activated sludge AS plant, prior to tertiary treatment using waste stabilisation ponds WSPs.

The water quality in the WSPs following the upgrade was significantly improved. The reduction in ammonium and potentially toxic free ammonia removed a control upon the growth of zooplankton, which may have contributed to decreases in algal biomass in the final ponds and consequently lower dissolved oxygen. Additionally, changes in inorganic nitrogen speciation contributed to a slightly elevated pH which reduced numbers of faecal coliforms in WSPs.

The AS pretreated influent recorded significantly lower inorganic molar N:P ratio compared to those fed with TF effluent Algae within the WSPs may now be nitrogen limited, a condition which may favour the growth of nitrogen-fixing cyanobacteria. The decrease in algal biomass and in dissolved oxygen levels may enhance sedimentary denitrification, further driving the system towards nitrogen limitation.

Pre- treatment of thickened waste activated sludge TWAS for enhanced biogas production via the application of a novel radial horn sonication technology. The efficacy of sonication as a pre- treatment to anaerobic digestion AD was assessed using thickened waste activated sludge TWAS.

Efficiency was measured in relation to solubilisation, dewaterability, and AD performance. An optimised experimental protocol was used as a pre- treatment for biochemical methane potential BMP testing and semi-continuous trials. Results demonstrate that the technology effectively disrupts the floc structures and filaments within the TWAS, causing an increase in solubilisation and fine readily digestible material. Partial-stream sonication sonicated to untreated TWAS resulted in a proportionate increase in biogas production illustrating the benefits of full-stream sonication.

Medical waste treatment and decontamination system. The invention discloses a tandem microwave system consisting of a primary chamber in which hybrid microwave energy is used for the controlled combustion of materials. A second chamber is used to further treat the off-gases from the primary chamber by passage through a susceptor matrix subjected to additional hybrid microwave energy.

Passive Treatment for Reducing Metal Loading. Scholze James E. Alleinan Steve R. Struss EdD. Smith This The re-use of Waste-Activated Sludge as part of a "zero-sludge" strategy for wastewater treatments in the pulp and paper industry. The possibility of introducing the thermo-alkali hydrolysis of Waste-Activated Sludge WAS was investigated, in order to enable the use of its solid residue as a raw material in cardboard production and the use of its liquid portion for anaerobic digestion in an UASB reactor.

The solid portion was hygienised, therefore making it possible to integrate it into the cardboard production as a raw material for less demanding cardboards. Combined treatment of alkaline and disperser for improving solubilization and anaerobic biodegradability of dairy waste activated sludge.

An investigation into the influence of combined alkaline and disperser pretreatment on sludge disintegration was studied. The effect of sludge pretreatment was evaluated by COD solubilization, suspended solids reduction and biogas production.

Not only the increase in biogas production was investigated, excluding protein hydrolysis was also performed successfully by this combined pretreatment even at low specific energy input. Thus, this chemo-mechanical is an effective method for enhancement of biodegradability and it laid the basis to produce higher biogas quantities, to improve clean energy generation from WAS.

Biological treatment of hazardous aqueous wastes. Studies were conducted with a rotating biological conractor RBC to evaluate the treatability of leachates from the Stringfellow and New Lyme hazardous- waste sites. The paper reports on the results from these experiments and the effectiveness of an RBC to adequately treat leachates from Superfund sites. The use of fly larvae for organic waste treatment.

The idea of using fly larvae for processing of organic waste was proposed almost years ago. Since then, numerous laboratory studies have shown that several fly species are well suited for biodegradation of organic waste , with the house fly Musca domestica L. House fly larvae develop well in manure of animals fed a mixed diet, while black soldier fly larvae accept a greater variety of decaying organic matter.

Blow fly and flesh fly maggots are better suited for biodegradation of meat processing waste. The larvae of these insects have been successfully used to reduce mass of animal manure, fecal sludge, municipal waste , food scrapes, restaurant and market waste , as well as plant residues left after oil extraction.

Higher yields of larvae are produced on nutrient-rich wastes meat processing waste , food waste than on manure or plant residues. Larvae may be used as animal feed or for production of secondary products biodiesel, biologically active substances. Waste residue becomes valuable fertilizer. During biodegradation the temperature of the substrate rises, pH changes from neutral to alkaline, ammonia release increases, and moisture decreases.

Microbial load of some pathogens can be substantially reduced. Both larvae and digested residue may require further treatment to eliminate pathogens. Facilities utilizing natural fly populations, as well as pilot and full-scale plants with laboratory-reared fly populations have been shown to be effective and economically feasible. The major obstacles associated with the production of fly larvae from organic waste on an industrial scale seem to be technological aspects of scaling-up the production capacity, insufficient knowledge of fly biology necessary to produce large amounts of eggs, and current legislation.

Technological innovations could greatly improve performance of the biodegradation facilities and. Annual waste reduction activities report. Issue 1. This report discusses the waste minimization activities for the Pinellas Plant. The Pinellas Plant deals with low-level radioactive wastes , solvents, scrap metals and various other hazardous materials.

The programs used for this simulated Cast Stone were gradient density change, compressive strength, and salt waste form phase identification. Gradient density changes show a favorable outcome by showing uniformity even though it was hypothesized differently. Jet Lowe - U. Bulky waste quantities and treatment methods in Denmark.

Bulky waste is a significant and increasing waste stream in Denmark. However, only little research has been done on its composition and treatment. In the present study, data about collection methods, waste quantities and treatment methods for bulky waste were obtained from two municipalities.

In addition a sorting analysis was conducted on combustible waste , which is a major fraction of bulky waste in Denmark. The amount of combustible waste could be significantly reduced through better sorting. Many of the waste fractions consisted of composite products that underwent thorough separation before being recycled. The recyclable materials were in many cases exported to other countries which made it difficult to track their destination and further treatment.

An important advantage of use of an aerobic biostabilization of waste prior to its disposal is that it intensifies the decomposition of the organic fraction of waste into the form which is easily assimilable for methanogenic microorganisms involved in anaerobic decomposition of waste in the landfill.

In this article it is presented the influence of aerobic pre- treatment of waste as well as leachate recirculation on susceptibility to biodegradation of waste in anaerobic laboratory reactors. Treatment of halogen-containing waste and other waste materials. A process for treating a halogen-containing waste material. The process provides a bath of molten glass containing a sacrificial metal oxide capable of reacting with a halogen in the waste material.

The sacrificial metal oxide is present in the molten glass in at least a stoichiometric amount with respect to the halogen in the waste material. The waste material is introduced into the bath of molten glass to cause a reaction between the halogen in the waste material and the sacrificial metal oxide to yield a metal halide.

The metal halide is a gas at the temperature of the molten glass. The gaseous metal halide is separated from the molten glass and contacted with an aqueous scrubber solution of an alkali metal hydroxide to yield a metal hydroxide or metal oxide-containing precipitate and a soluble alkali metal halide. The precipitate is then separated from the aqueous scrubber solution.

The molten glass containing the treated waste material is removed from the bath as a waste glass. The process of the invention can be used to treat all types of waste material including radioactive wastes. The process is particularly suited for separating halogens from halogen-containing wastes. A process is described for treating a halogen-containing waste material.

That the allowable project costs do not include a costs Utilizing waste activated sludge for animal feeding. Activated sludge has a high protein content and is a good source of B-group vitamins and generally also of minerals Ca, Mg, Fe and K. Propionibacterium freudenreichii can be readily incorporated into the activated sludge to synthesize vitamin B12, particularly high vitamin yields being obtained with sewage mixed with dairy waste.

Numerous examples of successful use of activated sludge in animal feeding are given. Method for aqueous radioactive waste treatment.

The present study deals with the determination of physical and chemical parameters in the treatment process of waste water by flocculation and coagulation processes using natural coagulants and assessing their feasibility for water treatment by comparing the performance with each other and with a synthetic coagulant.

Initial studies were done on the synthetic waste water to determine the optimal pH and dosage, the activity of natural coagulant, followed by the real effluent from tannery waste. The study reveals that the untreated tannery effluents can be treated with environmental confirmative naturally occurring coagulants.

Risk management in waste water treatment. With the continuous restructuring of the water market due to liberalisation, privatisation and internationalisation processes, the requirements on waste water disposal companies have grown. Increasing competition requires a target-oriented and clearly structured procedure.

At the same time it is necessary to meet the environment-relevant legal requirements and to design the processes to be environment-oriented. The implementation of risk management and the integration of such a management instrument in an existing system in addition to the use of modern technologies and procedures can help to make the operation of the waste water treatment safer and consequently strengthen market position. To achieve an identification of the risks as complete as possible, a subdivision of the kind of risks e.

The determination of the appropriate measures to handle a risk e. Different strategies can be applied here. On the one hand, the cause-oriented strategy, aiming at preventive measures which aim to reduce the probability of occurrence of a risk e.

On the other hand, the effect-oriented strategy, aiming to minimise the level of damage in case of an undesired occurrence e. Climate impact analysis of waste treatment scenarios--thermal treatment of commercial and pretreated waste versus landfilling in Austria.

A major challenge for modern waste management lies in a smart integration of waste -to-energy installations in local energy systems in such a way that the energy efficiency of the waste -to-energy plant is optimized and that the energy contained in the waste is, therefore, optimally utilized.

The extent of integration of thermal waste treatment processes into regular energy supply systems plays a major role with regard to climate control. In this research, the specific waste management situation looked at scenarios aiming at maximizing the energy recovery from waste i. Comparing dedicated waste -to-energy-systems based on the combined heat and power CHP process with concepts based on sole electricity production, the energy efficiency proves to be crucial with regard to climate control.

This underlines the importance of choosing appropriate sites for waste -to-energy-plants. This research was looking at the effect with regard to the climate impact of various waste management scenarios that could be applied alternatively by a private waste management company in Austria. The research is, therefore, based on a specific set of data for the waste streams looked at waste characteristics, logistics needed, etc.

Furthermore, the investigated scenarios have been defined based on the actual available alternatives with regard to the usage of treatment plants for this specific company.

Potassium ferrate addition as an alternative pre- treatment to enhance short-chain fatty acids production from waste activated sludge. A potentially practical technology based on ferrate VI , i. The mechanism study showed that PF accelerated the release rate of both intracellular and extracellular constituents. And the activities of key hydrolytic enzymes were much improved with PF addition.

Moreover, PF positively enriched the abundance of microorganisms responsible for WAS hydrolysis and SCFAs production, especially acetic acid-forming characteristic genera such as Petrimonas, Fusibacter and Acetoanaerobium.

Besides, the incubation time of acidogenesis and methanogenesis were separated by PF. Recovery of nitrogen and phosphorus from alkaline fermentation liquid of waste activated sludge and application of the fermentation liquid to promote biological municipal wastewater treatment. In previous publications we reported that by controlling the pH at Improved bioproduction of short-chain fatty acids SCFAs from excess sludge under alkaline conditions.

Hydrolysis and acidification of waste activated sludge at different pHs. Water Res. This paper investigated the simultaneous recovery of NH 4 -N and SOP from WAS alkaline fermentation liquid and the application of the fermentation liquid as an additional carbon source for municipal wastewater biological nitrogen and phosphorus removal.

Under the optimum conditions, the predicted and experimental recovery efficiency was respectively The addition of fermentation liquid didn't significantly affect nitrification. The enhancement of phosphorus and nitrogen. Hazardous waste treatment for spent pot liner. The spent pot liner is the largest solid waste produced by the electrolytic aluminum industry, composed of a series of substances that accumulate in the containers with reduced aluminum during the process of bauxite purification and refining.

More and more spent pot liner is accumulated and needs to be dealt with. This paper discusses the composition and harm of solid waste. This paper expounds the comprehensive utilization value and disposition of the waste pot liner. Gravitational sedimentation of flocculated waste activated sludge.

The sedimentation characteristics of flocculated wastewater sludge have not been satisfactorily explored using the non-destructive techniques, partially owing to the rather low solid content ca. This paper investigated, for the first time, the spatial-temporal gravitational settling characteristics of original and polyelectrolyte flocculated waste activated sludge using Computerized Axial Tomography Scanner. The waste activated sludge possessed a distinct settling characteristic from the kaolin slurries.

The waste activated sludges settled more slowly and reached a lower solid fraction in the final sediment than the latter. Flocculation markedly enhanced the settleability of both sludges. Although the maximum achievable solid contents for the kaolin slurries were reduced, flocculation had little effects on the activated sludge.

The purely plastic rheological model by Buscall and White J Chem Soc Faraday Trans 1 83 interpreted the consolidating sediment data, while the purely elastic model by Tiller and Leu J. Flocculation produced lower yield stress during transient settling, thereby resulting in the more easily consolidated sludge than the original sample. Meanwhile, the flocculated activated sludge was stiffer in the final sediment than in the original sample. The data reported herein are valuable to the theories development for clarifier design and operation.

Improving biogas production from continuous co-digestion of oily wastewater and waste-activated sludge by hydrodynamic cavitation pre- treatment. The main objective of the present research was the enhancement of biogas production by the application of HC pretreatment. As a control system, an identical digestion reactor was set up for co-digestion of the WAS and the OWW without pretreatment.

The loading rate, accordingly, increased from 0. The biogas volume was recorded online and its quality was analyzed regularly. Reducing the HRT decreased biogas production from the main reactor while that of the control reactor was more or less constant. The main reactor experienced no clogging or accumulation of fatty materials. During NPP operation, several waste streams are generated, caused by different technical and physical processes. Besides others, liquid waste represents one of the major types of waste.

Depending on national regulation for storage and disposal of radioactive waste , solidification can be one specific requirement. To accommodate the global request for waste treatment systems Westinghouse developed several specific treatment processes for the different types of waste.

In the period of to Westinghouse awarded several contracts for the design and delivery of waste treatment systems related to the latest CPR nuclear power plants. This plant already passed the hot functioning tests successfully in June and is now ready and released for regular operation.

The 'Follow on plants' are designed to package three 'typical' kind of radioactive waste : evaporator concentrates, spent resins and filter cartridges. The purpose of this paper is to provide an overview on the Westinghouse experience to design and execution of cementation facilities. Hydrometallurgical experiments are generally required to assess the appropriate treatment process before the establishment of the industrial recovery process for waste battery materials.

The effects of acid systems and oxidants in metal leaching were studied. The comprehensive leaching effects of the citric acid were superior to the sulfuric acid. The potassium permanganate inhibits the dissolution of metals. Thermodynamic calculations showed that metals precipitate more easily in sulfuric acid system than in citric acid system.

Crude manganese carbonate and a cobalt-nickel enriched liquid were obtained by selective precipitation in raffinate using an ammonium bicarbonate solution. The cobalt-nickel-copper enriched liquid was finally obtained. A raw sewage treatment process is disclosed in which substantially all the non-dissolved matter, suspended in the sewage water is first separated from the water, in which at least organic matter remains dissolved.

The activated carbon and ash material adsorbs the organic matter dissolved in the water and is thereafter supplied in a counter flow direction and combined with the incoming raw sewage to at least facilitate the separation of the non-dissolved settleable materials from the sewage water. Carbon and ash material together with the non-dissolved matter which was separated from the sewage water are pyrolyzed to form the activated carbon and ash material.

Studies have been conducted with a rotating biological contractor RBC to evaluate the treatability of leachates from the Stringfellow and New Lyme hazardous waste sites. The leachates were transported from the waste sites to Cincinnati at the United States Environmental Protect Fluidized bed steam reformed mineral waste form performance testing to support Hanford Supplemental Low Activity Waste Immobilization Technology Selection.

This report describes the benchscale testing with simulant and radioactive Hanford Tank Blends, mineral product characterization and testing, and monolith testing and characterization. The FBSR technology can process these wastes into a crystalline. Final report, Mar Sep An attempt was also made to determine fluorocarbons as fluoride.

Membrane fluxes were also determined. An economic analysis of the membrane treatment processes indicates that it is extremely favorable in recovering the AFFF wastewater for reuse. Pilot-scale studies are, however, necessary to fully establish the process feasibilities and economics of the AFFF recovery system. The Upstream Optioneering project was created by the Nuclear Decommissioning Authority NDA Radioactive Waste Management Directorate RWMD to support the development and implementation of opportunities to optimise the management of UK higher activity waste , spent fuel and other materials that may be disposed of in a geological disposal facility.

Prioritisation ensured that resources were deployed appropriately and opportunities can be realised before the potential benefit diminishes. Work varies from direct implementation of opportunities to scoping studies that may pave the way for more detailed subsequent work by Site Licence Companies.

This paper provides an overview of the Upstream Optioneering project focusing particularly on Phases 2 and 3 , summarises work carried out to date within the three year work programme, and provides some examples of the main findings concerning specific opportunities from Year One of the Phase 3 work programme. Detection, composition and treatment of volatile organic compounds from waste treatment plants. Environmental policies at the European and global level support the diversion of wastes from landfills for their treatment in different facilities.

Organic waste is mainly treated or valorized through composting, anaerobic digestion or a combination of both treatments. Thus, there are an increasing number of waste treatment plants using this type of biological treatment. During waste handling and biological decomposition steps a number of gaseous compounds are generated or removed from the organic matrix and emitted. Many of these compounds are also sources of odor nuisance.

In fact, odors are the main source of complaints and social impacts of any waste treatment plant. This work presents a summary of the main types of VOC emitted in organic waste treatment facilities and the methods used to detect and quantify these compounds, together with the treatment methods applied to gaseous emissions commonly used in composting and anaerobic digestion facilities. Over the past fewyears, it has become increasinsly evident that land disposal of hazardous wastes is at least only a temporary solution for much of the wastes present at Superfund sites.

The need for more Iong-term, permanent " treatment solutions as alternatives to land disposal The disposal of waste asbestos from decommissioning activities is becoming problematic in countries which have limited disposal space. A particular challenge is the disposal of asbestos wastes from the decommissioning of nuclear sites because some of it is radioactively contaminated or activated and disposal space for such wastes is limited.

The common practice to date for asbestos wastes is disposal in licensed landfills. In some cases, compaction techniques are used to minimize the disposal space requirements. Social pressures have resulted in changes to disposal regulations which, in turn, have resulted in the closure of some landfills and increased disposal costs. In the UK, tens of thousands of tonnes of asbestos waste will result from the decommissioning of nuclear sites over the next 20 years.

In Japan, it is estimated that over 40 million tonnes of asbestos materials used in construction will require disposal. Methods for the safe and cost effective volume reduction of asbestos wastes are being evaluated for many sites. The full-scale treatment operations in Japan have also included contaminated soils and debris. Results from recent full-scale treatment operations in Japan are discussed and plans for GeoMelt treatment of UK nuclear.

Radiological Monitoring of Waste Treatment Plant. Scheduled waste in West Malaysia is handled by Concession Company and is stored and then is incinerated. It is known that incineration process may result in naturally occurring radioactive materials NORM to be concentrated. In this study we have measured three samples consist of by-product from the operation process such as slag, filter cake and fly ash.

Other various environmental media such as air, surface water, groundwater and soil within and around the plant have also been analysed for their radioactivity levels. The concentration of Ra, Ac and K in slag are 0. The concentration in fly ash is 0. For filter cake, the concentration is 0. The external radiation level ranges from 0. The concentration level of radon and thoron progeny varies from 0.

For soil samples, the activity ranges from 0. While activity in water, except for a trace of K, it is non-detectable. On-site or off-site treatment of medical waste : a challenge. Treating hazardous-infectious medical waste can be carried out on-site or off-site of health-care establishments.

Nevertheless, the selection between on-site and off-site locations for treating medical waste sometimes is a controversial subject. Currently in Iran, due to policies of Health Ministry, the hospitals have selected on-site-treating method as the preferred treatment. The objectives of this study were to assess the current condition of on-site medical waste treatment facilities, compare on-site medical waste treatment facilities with off-site systems and find the best location of medical waste treatment.

To assess the current on-site facilities, four provinces and 40 active hospitals were selected to participate in the survey. For comparison of on-site and off-site facilities due to non availability of an installed off-site facility Analytical Hierarchy Process AHP was employed. The result indicated that most on-site medical waste treating systems have problems in financing, planning, determining capacity of installations, operation and maintenance.

AHP synthesis with inconsistency ratio of 0. According to the results of study it was concluded that the off-site central treatment can be considered as an alternative. To begin and test this plan and also receive the official approval, a central off-site can be put into practice, at least as a pilot in one province.

Next, if it was practically successful, it could be expanded to other provinces and cities. Revision 1. This section provides a description of the Hanford Site, identifies the proposed method of Area Waste Acid Treatment System WATS closure, and briefly summarizes the contents of each chapter of this plan. Grades This brochure contains an engineering activity for upper elementary, middle school, and high school students that examines the transportation of radioactive waste.

The activity is designed to inform students about the existence of radioactive waste and its transportation to disposal sites. Students experiment with methods to contain the waste and…. A bio-hybrid anaerobic treatment of papaya processing wastes. Hybrid anaerobic treatment of papaya processing wastes is technically feasible. Elimination of post-handling and treatment of digested effluent can also be achieved. The system is more suitable for those processing plants with a waste amount of more than 3, metric tons per year.

Both waste streams are then separately vitrified as glass and sealed in canisters. Options are being explored to immobilize the LAW portion of the tank waste , i. This report contains results of testing of a simulant that represents the projected composition of the feed to the Supplemental LAW process.

This feed composition is not identical to the aqueous tank waste fed to the Waste Treatment Plant because it has been processed through WTP Pretreatment facility and therefore contains internal changes and recycle streams that will be generated within the WTP process. Audits of hazardous waste TSDFs let generators sleep easy. This investigation must include an environmental and a financial audit. Simple audits may be performed by the hazardous waste generator, while more thorough ones such as those performed for groups of generators are more likely to be conducted by environmental consultants familiar with treatment , storage, and disposal techniques and the regulatory framework that guides them.

Development and testing of a wet oxidation waste processing system. The wet oxidation process is considered as a potential treatment method for wastes aboard manned spacecraft for these reasons: 1 Fecal and urine wastes are processed to sterile water and CO2 gas.

However, the water requires post- treatment to remove salts and odor; 2 the residual ash is negligible in quantity, sterile and easily collected; and 3 the product CO2 gas can be processed through a reduction step to aid in material balance if needed. Reaction of waste materials with oxygen at elevated temperature and pressure also produces some nitrous oxide, as well as trace amounts of a few other gases.

The Environmental Protection Agency EPA has declared that vitrification is the "best demonstrated available technology" for high- level radioactive wastes HLW Federal Register and has produced a handbook of vitriilcation technologies for treatment of hazardous and radioactive waste US EPA, The goal of this study is to optimize the composition of glass for EVB waste at LANL, and present the basic techniques and tools for developing optimized glass compositions for other Pu-bearing materials in the complex.

This report outlines an approach for glass formulation with fixed property restrictions, using glass property-composition databases. This approach is applicable to waste glass formulation for many variable waste streams and vitrification technologies.. Also reported are the preliminary property data for simulated evaporator bottom glasses, including glass viscosity and glass leach resistance using the Toxicity Characteristic Leaching Procedure TCLP.

Oxidation and ozonation of waste activated sludge. In this bench-scale study, the treatment of waste activated sludge WAS was evaluated using aerobic digestion and ozonation. Two, 2-L batch digesters, one aerated and the other one ozonated, were operated for 30 days in each phase of the study. The aerated digester simulated the aerobic digestion process and served as control to the ozonated digester.

In Phase I, the aerated digester was supplied mg O 2 min - 1 , whereas, the ozonated digester was supplied 0. In Phase II, the oxygenation rate to the aerobic digester was increased to 1, mg O 2 min - 1 while the ozonation rate was reduced to 0. The degradation rate constant K d based on degradable TS for the ozonated digester varied from 0.

Soluble chemical oxygen demand SCOD concentrations in the sludge supernatant increased with digestion time, especially in the ozonated digester. Approximately 0. The average quantity of oxygen required during aerobic digestion was 1. High density Polyethylene plastic waste treatment with microwave heating pyrolysis method using coconut-shell activated carbon to produce alternative fuels. Pyrolysis is a technology that could crack polimer such as plastic waste into alternative fuels.

This research uses microwave heating methode, which more efficient than conventional heating methode. The plastic waste used is grams of HDPE, with feed to catalyst weight ratio are , 0. Result shows that yield of liquid and gas product is A number of Hanford tanks received waste containing organic complexants, which increase the volubility of Sr and transuranic TRU elements.

Wastes from these tanks require additional pretreatment to remove Sr and TRU for immobilization as low activity waste Waste Envelope C. This was a result of the formation of poor filtering iron solids. Battelle conducted preliminary small-scale experiments to determine the effectiveness of permanganate treatment with AN waste samples that had been archived at Battelle from earlier studies.

The final series included experiments with actual AN diluted feed that had been obtained specifically for BNFL process testing. A free hydroxide concentration of 0. The best results were obtained when reagents were added in the sequence Sr followed by permanganate with the waste at ambient temperature. In addition, another problem was the illegal discharge of septic sewage collected from homes into rivers or on land. The nonoperational The discharge of raw. More than 56 million gallons of radioactive and hazardous waste are stored in underground storage tanks at the U.

The WTP includes a pretreatment facility to separate the wastes into a small volume of high-level waste HLW containing most of the radioactivity and a larger volume of low- activity waste LAW containing most of the nonradioactive chemicals.
