Download or read book Phosphorus Removal Within Existing Wastewater Treatment Facilities written by B. I. Boyko and published by Environmental Protection Service, Environment Canada. This book was released on 1976 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The various projects reported herein were undertaken to assist in the implementation of the Province of Ontario's phosphorus control program. Under this five-year program, phosphorus removal was to be initiated on the discharges of more than 170 existing wastewater treatment plants serving some five million persons. In order to implement this program, a methodology to predict the coagulant best suited for phosphorus removal at any particular treatment facility was required. It was also necessary to determine whether the chemicals used for phosphorus removal would have any physical or process effects on present wastewater treatment processes, facilities, methods of sludge treatment, and subsequent sludge disposal practices. This report discusses coagulation prediction and prime coagulant selection, and the operational results, problems and design considerations derived from a series of full scale studies. The study concluded that phosphorus removal may be readily implemented with minimal capital expenditure at operating municipal wastewater treatment facilities of all designs currently in use in Ontario.

Available in PDF, EPUB and Kindle. Book excerpt: Biological phosphorus (bio-P) removal has become a reliable and well-understood process within wastewater treatment, despite being one of the most complex processes in the activated sludge process. Extended fundamental and full-scale research has been carried out into the bio-P process and the state-of-the-art is described in this report. A summarising historical overview gives insight into the establishment of the appropriate microbiological and biochemical basis of the process and the development of bio-P configurations in practice. Aspects of the bio-P process that have a direct influence on the efficiency of phosphorus removal are subjected to an in-depth investigation. This report presents guidelines for design and dimensioning in order to introduce and/or optimise the bio-P process in practice. Twelve bio-P installations are extensively described and the operational results and experiences are related to existing bio-P knowledge and guidelines. Based on a number of parameters, a comparison is made between the described bio-P plants. A steady state model is verified with extensive periods of practical experience of the plants. The bio-P model, which is provided on CD-ROM (available for download here), offers a reliable insight into the bio-P process, coupled with sensitivity analyses regarding wastewater characteristics and process parameters for the anaerobic volume and the P-ortho concentration in the final effluent. The report ends with a systematic approach to the design of the bio-P process, based on the background of the bio-P process itself, much practical experience and the analysis of operational bio-P plants. Also presented is a systematic approach to tackle operational aspects of the bio-P process in order to generate an acceptable low P effluent concentration. This optimisation of the bio-P process operation is supported by a decision diagram. Biological Phosphorus Removal will be an invaluable source of information for all those concerned with wastewater treatment, including plant managers, process designers, consultants and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive text provides the reader with both a detailed reference and a unified course on wastewater treatment. Aimed at scientists and engineers, it deals with the environmental and biological aspects of wastewater treatment and sludge disposal.The book starts by examining the nature of wastewaters and how they are oxidized in the natural environment. An introductory chapter deals with wastewater treatment systems and examines how natural principles have been harnessed by man to treat his own waste in specialist reactors. The role of organisms is considered by looking at kinetics, metabolism and the different types of micro-organisms involved. All the major biological process groups are examined in detail, in highly referenced chapters; they include fixed film reactors, activated sludge, stabilization ponds, anaerobic systems and vegetative processes. Sludge treatment and disposal is examined with particular reference to the environmental problems associated with the various disposal routes. A comprehensive chapter on public health looks at the important waterborne organisms associated with disease, as well as removal processes within treatment systems. Biotechnology has had an enormous impact on wastewater treatment at every level, and this is explored in terms of resource reuse, biological conversion processes and environmental protection. Finally, there is a short concluding chapter that looks at the sustainability of waste water treatment. The text is fully illustrated and supported by over 3000 references.

This book was released on 1986 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation addressed the technical and economic feasibility ofretrofitting existing Canadian municipal wasterwater treatment plants forenhanced biological phosphorus removal (EBPR). Various EBPR processes werereviewed briefly and the practicality of using these technologies compared toconventional chemical precipitation technology for removing phosphorus frommunicipal wastewaters was assessed. An attempt was made to identify thetype and size of existing treatment plants in Canada that would be mostamenable to retrofit for enhanced biological phosphorus removal. Costs werecompared for a number of EBPR alternatives and chemical precipitation. Thisstudy was not limited to a single specific plant, but was conducted inbroader context so that those conditions under which either chemical orenhanced biological phosphorus removal was more cost-effective could beidentified.

This book was released on 1971 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hot waste pickle liquor (ferrous sulfate) as an iron source was successful in precipitating phosphorus from solution in a 115 mgd East Plant of Milwaukee's Jones Island Activated Sludge Wastewater Treatment Plant. An 85 mgd section of the plant receiving the same influent was operated as a control. The East Plant with iron addition, achieved 91.3% removals (0.70 mg/1 P effluent residual), while the control West Plant removed 83.1% (1.4 mg/1 P residual). Comparison of efficiencies of purification, pH, alkalinity, and microscopic examinations of the sludge microorganism indicated that the addition of unneutralized waste pickle liquor did not adversely affect purification processes.

This book was released on 2010 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to analyze the current chemical phosphorus removal system and to compare it to a retrofit biological phosphorus removal system for the Waukesha Wastewater Treatment Plant. Phosphorus, an essential nutrient for all living things, causes serious eutrophication problems in receiving water bodies if not controlled. The Waukesha Wastewater Treatment Plant was chosen for an analysis of its existing chemical phosphorus removal system because data were available and there were no recent major modifications to the plant. The analysis of the phosphorus removal process was done to evaluate the feasibility of converting from a chemical phosphorus removal system to a biological phosphorus removal (BPR) system. This analysis found that a biological system appears to be feasible and promising based on analysis of the performance, cost, and environmental impacts. The benefits that could be acquired from this process outweigh the negatives. The analysis found that biological phosphorus removal could achieve the required 1 mg P/l effluent requirements for the plant. The benefits to the plant include: increased solids handling capacity resulting from a reduction of 255 tons per year of solids production from chemical additions, lower salinity in the effluent water, and reduced biosolids costs of $20,500 per year. The reduction in annual operational costs would result in a payback period of less than 3 years. Further investigation of this retrofit is justifiable for the City of Waukesha and the Waukesha Wastewater Treatment Facility managers.
