Download or read book Biological Phosphorus Removal written by P. M. J. Janssen and published by IWA Publishing. This book was released on 2002-05-31 with total page 228 pages. 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.

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.

Book excerpt: Special Offer: Cao Ye Shi Author Set - Buy all three books together and save a total £76! Biological Phosphorus Removal Activated Sludge Process in Warm Climates presents the results of detailed research on the Enhanced Biological Phosphorus Removal (EBPR) activated sludge process under warm climate conditions (20oC - 30oC), which is part of the R & D program of Public Utilities Board (PUB) Singapore. The investigations and studies presented in this book are application-oriented, but at the same time the studies aim at an insightful understanding of the EBPR with the knowledge of the latest development in academic field. The focus points are: EBPR performance of laboratory-scale and full-scale activated sludge processes under the site conditions in warm climates The carbon competition and distribution between PAO and GAO (and denitrifiers) in the process The stoichiometry and kinetics of P-release, COD uptake in the anaerobic environment and P-uptake in the aerobic environment under different temperatures and operating conditions PAO and GAO population fractions, shift and dominance studies using FISH and batch tests The inter-relationships between the system performance, process design and the microbial community EBPR for industrial wastewater (high ratio of feed COD/P) treatment under warm climates. Together with the preceding book – Biological Nitrogen Removal Activated Sludge Process in Warm Climates – published by IWA in 2008, this book fills the gap of biological nutrient (nitrogen and phosphorus) removal in warm climates and provides unique experiences and knowledge for Process and design researchers and engineers in wastewater research, students and academic staff in Civil/Sanitation/Environment Departments, as well as Managers, Engineers and Consultants in water companies and water utilities.

Download or read book Phosphorus Removal with Pickle Liquor in an Activated Sludge Plant written by Raymond D. Leary and published by . 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.
