    Swayne, Michael D.: Review of techniques for treatment and disposal of phosphorus-laden chemical sludges / (Cincinnati, Ohio: Environmental Protection Agency, Office of Research and Development, Municipal Environmental Research Laboratory ; Springfield, Va.: for sale by the National Technical Information Service, ), also by Curtis J. for direct land disposal, such as in a solar evaporation pond. Or, it may be acceptable for discharge to a municipal wastewater treatment system. If it does not meet environmental standards for one of these types of disposal, further, "polishing" treatment steps (e.g., car-bon adsorption) will be required. Alternatively, chemical oxidation.

    Wastewater Treatment: Chemical Precipitation - View presentation slides online. It deals with the wastewater treatment by chemical precipitation to improve the performance of primary clarifiers, for the removal of heavy metals and for the removal of phosphorus from the wastewater. it also deals with the estimation of the chemical sludges generated during the chemical precipitation process. The upgrading of treatment plants, particularly the addition of phosphorus removal practices, results in increased volumes of biological or chemical sludges, which may be more difficult to handle than a simple primary sludge. As treatment plants become more sophisticated, the sludge handling and disposal problem grows.

    ment and disposal facilities for St. Louis wastewater treatment plants were de scribed by Mattei At the two largest plants, vacuum filtration and incineration are used. Facilities for management of sludges from physical, chemical, and bio logical treatment facilities . The Chemical Water and Wastewater Treatment Series provides authoritative coverage of the key current developments in the chemical treatment of water and wastewater in theory or practice and related problems such a s sludge production and properties, and the reuse of chemicals and chemically-treated waters and sludges.

EPA/ August REVIEW OF TECHNIQUES FOR TREATMENT AND DISPOSAL OF PHOSPHORUS-LADEN CHEMICAL SLUDGES by Curtis J. Schmidt LeAnne E.

Hammer Michael D. Swayne SCS ENGINEERS Long Beach, California Contract No. Project Officer R. Villers Wastewater Research Division Municipal Environmental Research Laboratory Cincinnati, Ohio. The report summarizes the effects of phosphorus removal by chemical addition on sludge handling and disposal options at full-scale wastewater treatment plants.

American and Canadian plants which generate phosphorus-laden chemical sludges were surveyed by questionnaire, and responses were received. Investigations at selected plants that were using a variety of phosphorus removal. treatment processes are covered by full and interlinked design examples which are built up throughout the series and the books, from the determination of the waste-water characteristics, the impact of the discharge into rivers and lakes, the design of several wastewater treatment processes and the design of the sludge treatment and disposal units.

Abstract. Mode of access: Internet Topics. Textile Wastewater Treatment Options: A Critical Review Libra JA, Sosath F () Combination of biological and chemical processes for the treatment of textile wastewater containing reactive dyes. Dewatered Sludges Dewatering converts sludge from a flowing mixture of liquids and solids to a cake-like substance more readily handled as a solid.

The characteristics of dewatered sludge depend on the type of sludge, chemical conditioning, and treatment processes employed.

A wide variety of sludge treatment processes are used to prepare municipal wastewater treatment sludges for use or disposal. The objectives of most municipal sludge treatment processes are to reduce the water content of sludges, to avoid complications from decomposition of the biologically degradable fraction of sludges, and to reduce the.

The paper also reviews and evaluates ways of collecting data on quantity, quality, methods of sewage sludge treatment, and disposal. The existing problems have also been identified with regard to the management of sewage sludge in the sewage treatment areas (legal, economic, technical, and environmental issues).

The levels of post-treatment dewatering necessary to achieve the undrained strengths reported in the ‘Monofilling’ and ‘Co-disposal at sanitary landfills’ sections can be achieved at the municipal works using recessed-plate filter press and belt dryer machines after the chemical conditioning of the sludge by-product (O’Kelly, ; O.

The ease of treatment of animal or vegetable greases or oils compared with those found in petrochemical processing wastes; the concentration ranges of greases and oil found in various wastewaters, e.g., to mg/l in petroleum refinery wastewaters; physical treatment by gravity separation, dissolved air flotation, and gas flotation; free-floating oil and emulsions; chemical treatment.

Sewage sludges generation and their disposal have become one of the greatest challenges of the 21st century. They have great microbial diversity that may impact wastewater treatment plant (WWTP) efficiency and soil quality whether used as fertilizers.

Therefore, this research aimed to characterize microbial community diversity and structure of 19 sewage sludges from São Paulo, Brazil, as well.

The aim of this study was to review the current meth- ods of disposal and treatment of pesticides and to per- form a comparative analysis to determine the most ap- propriate method for on farm use.

2. Pesticide Disposal Methods. The methods for the disposal of low level pesticides (Table 5) include: land cultivation, disposal pits, evapo.Solid waste management in developing countries is often unsustainable, relying on uncontrolled disposal in waste dumps.

Particular problems arise from the disposal of treatment residues generated by removing arsenic (As) from drinking water because As can be highly mobile and has the potential to leach back to ground and surface waters.

This paper reviews the disposal of water treatment wastes.Wastewater treatment chemicals including polymers, flocculants, defoamers, sludge conditioners and more for industrial and municipal applications.
