At the present time, one of the most common methods of disposing the municipal solid wastes (MSW) is burial in sanitary landfills, where take place, long-term complex of physico-chemical and biochemical processes of decomposition. It was developed modeling of the natural process of decomposition of the solid Municipal wastes in cross electromechanical fields. The synthesized pellets was studied by IR spectroscopy. Residual hydrocarbons has a complex structure, represented by δ-lactones, cyclopentanone. The results of treatment of husk show there were the characteristic frequencies related to the OH group, indicating that the synthesis of dimers of branched chain alcohols (glycerides). Analysis of model shows that hydrocarbon product formed by the method of matching the external effects of the internal response of the reacting carbon-water composition.

The paper describes specific changes in the quality of the Danube river water under the conditions of backwater effects in the Hydropower Plant Djerdap I storage. The results of longterm tests in five profiles of the investigated section, at various discharges give a global view of the intensity of changes in the composition of water mass. The analysis included changes in the contents of: organic matter, oxygen regime, reduction of turbidity and changes in the composition and abundance of plankton. The specific changes in the domain of physico-chemical and biochemical processes and changes in the biological status of the watercourse (composition and structure of plankton) at varying retention times complete the picture of short-term changes in the investigated system. Presentation of some settling effects and processes in the sediment of the storage provides an idea of some long-term changes in the conditions of backwater effects of the Danube in the investigated section.

Energy recovery potential of a mesophilic co-digester treating OFMSW and primary sludge at an integrated biomethanization plant was investigated based on feasibility study results. Since landfilling is still the main solid waste disposal method in Turkey, land scarcity will become one of the most important obstacles. Restrictions for biodegradable waste disposal to sanitary landfills in EU Landfill Directive and uncontrolled long-term contamination with gas emissions and leachate necessitate alternative management strategies due to rapid increase in MSW production. Moreover, since energy contribution from renewable resources will be required more in the future with increasing oil prices and dwindling supplies of conventional energy sources, the significance of biogas as a renewable fuel has been increased in the last decade. Results indicated that almost 93% of annual total cost can be recovered if 100% renewable energy subsidy is implemented. Besides, considering the potential revenue when replacing transport fuels, about 26 heavy good vehicles or 549 cars may be powered per year by the biogas produced from the proposed biomethanization plant (PE = 100,000; XPS= 61 g TS/PE⋅day;XSS-OFMSW=50 g TS/PE⋅day).

Abstract Nowadays, in India, the incidents such as fire, groundwater contamination and emission of methane due to the open dumping of municipal solid wastes have become very common. To overcome these issues and also to reduce the foul smell emanating from the yards due to rain drenching the piles of accumulated wastes, sanitary landfills with proper leachate movement control facilities and recycling of leachates should be adapted. When landfill squanders (Municipal solid waste) debases and downpour washes through the solid wastes, the leachate is formed. The Leachate is a dark fluid containing organic and inorganic chemicals, heavy metals and pathogens. Leachate may permeate through the landfill liners and subsoil, causing contamination of surface water and sub - surface waters, which results to several health hazards. The synthesis of waste changes drastically over the life of the landfill because of the presence of organic and inorganic substances. This paper focuses towards the control of leachate movement in a sanitary landfill and partial treatment of leachate using HDPE (High Density Poly Ethylene) sheets, such that the partially treated leachate meets the standards prescribed for the quality of Irrigation water. In this paper, the characteristics of leachate were studied by filtering it through 1, 2 and 3 layers of HDPE sheets respectively. When analyzed, the characteristics of leachate such as pH, Turbidity, BOD, COD, TSS and TDS shows that the leachate collected from 3 layered HDPE filtration system has better quality than the other two systems and it could be used for irrigation purposes as a tool to ensure sustainability by contributing towards the reduction of water scarcity issue.

For the municipal solid waste (MSW) to be used in a proper way, it is necessary to implement clean technologies capable of thermal treatment of MSW and RDF in order to produce heat and electricity while meeting current ecological requirements. Nowadays, a number of technologies for MSW/RDF thermal treating are being used worldwide. Among them, the most proven technologies, applicable for industrial introduction, have been considered while analyzing their advantages/ disadvantages accounting for local conditions of Ukraine.

Medical, social and economic relevance of inflammatory diseases of the woman's reproductive organs requires a very careful attitude to the diagnosis and treatment of this pathology. The number of patients with genital infections and inflammatory diseases of the pelvic organs can takes the first place in structure of gynecological morbidity, and is 60.4-65.0%, and this fact is not unique to Russia, but all over the world. Incidence rate of inflammatory diseases of the pelvic organs in the first decade of the twenty-first century is increased at 1.4 times in patients who are from 18 to 24 years old and at 1.8 times in patients aged 25-29 years. At the same time, the cost of diagnosis and treatment has increased, reaching 50-60% of the total cost of providing gynecological care for population. The inflammatory diseases of pelvic organs are a collective concept. It includes of various nosological forms. There are numerous contradictions in the views on diagnostic approaches and treatment tactics, the nature of screening and control over the long-term results of treatment, the etiological and pathogenetic significance of various microorganisms found in the genital tract in patients with inflammatory diseases of the pelvic organs. Currently, there are many opinions among specialists about diagnostic approaches and treatment tactics, the type of screening and monitoring the long-term results of treatment, the etiological and pathogenetic role of various microorganisms which can be found in the genital tract in patients with inflammatory diseases. This review presents the results of a modern approach to the diagnosis, management and rehabilitation of patients with inflammatory diseases of the pelvic organs.

The immediate and long-term results of treatment of 30 patients with severe pain syndrome of the lumbar region, who underwent operations on denervation of DOS, were studied. The aim of the study was to evaluate the effectiveness of minimally invasive technologies for the treatment of pain in the lumbar region (denervation of DOS), to study the near and distant results of these treatment methods. Denervation DOS is an effective minimally invasive method for the treatment of facet syndrome caused by spondylarthrosis. It allows in the early and distant postoperative periods to significantly reduce the pain syndrome and improve the quality of life of patients.

Optimum Dosage

Conditioning of sludges improves dewatering characteristics and reduces the quantity of sludge to be handled. Anaerobic digested sludge collected from a sewage treatment plant contained 1.8% to 8% oil. The increase of specific resistance and capillary suction time (CST) with increasing oil content observed in these samples indicates the interference of oil in dewatering. It has been found that addition of municipal solid wastes incinerator fly ash decreases the specific resistances and capillary suction times of oily sludges rapidly up to 3% dosage. Beyond 3% fly ash, the decrease is less significant and the solids content in the sludge cake increases. This optimum dosage remains the same for sludges with varying oil contents from 1.8% to 12%. The total suspended solids of filtrate decreases with fly ash dosage but the toxic concentrations of heavy metals increases considerably. However at the optimum dosage of 3%, concentrations of heavy metals are within the limits for discharging into the sewers. The correlations of CST with the dewatering characteristics such as specific resistance, filter yield and corrected filter yield are established. These correlations can be used to obtain a quick prediction on dewaterability.
