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.

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.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With growing emphasis on environmental and economic sustainability worldwide, modern municipal wastewater treatment plants (WWTPs) are striving to reduce consumption of resources and ensure increased recycling and reuse of nutrients and energy contained in the wastewater. In a trade-off between enhanced P removal (to meet stringent effluent limits) and increased resource (e.g., energy, chemical) usage, it is critical for the treatment plants to be able to select the most appropriate technology. To this end, this study has combined mathematical modeling and experimental data from recent literature to perform a comprehensive evaluation of established/emerging P recovery/removal technologies considering technical, economic and energy sustainability aspects. For technical evaluations, full-scale designs of high performing P removal technologies (e.g., Modified University of Cape Towne process, Bardenpho process, membrane bioreactors, IFAS-EBPR, struvite recovery, tertiary reactive media filtration) were developed and simulated using a widely-used Windows-based process model simulating software BioWin v. 5.3 (EnviroSim Associates Ltd., Canada). The treatment configurations were evaluated in terms of performance and cost effectiveness ($/lb of P removed). Results show that the unit cost for P removal in different treatment alternatives range from $42.22 to $60.88 per lb of P removed. The MUCT BNR+ tertiary reactive media filtration proved to be one of the most cost effective configurations ($44.04/lb P removed) delivering an effluent with total P (TP) concentration of only 0.05 mg/L. Although struvite recovery resulted in significant reduction in biosolids P, the decrease in effluent TP was not sufficient to meet very stringent discharge standards. Emerging low energy mainline (LEM) treatment layouts consisting of energy efficient and innovative technologies has the potential to improve the overall sustainability of WWTPs. To evaluate the LEM treatment schemes, a configuration consisting of fine screen pretreatment, anaerobic membrane bioreactor (AnMBR) for BOD and TSS removal, reactive filter media for adsorptive P removal, and cold partial nitritation/Anammox process for N removal was simulated using operational conditions that are typical for a mid-size WWTP in the US. Our simulation results indicated that the LEM scheme could reduce the net energy requirement for treatment by about 0.46 kWh/m3 (~ 94%) compared to a conventional activated sludge system. The removal efficiencies of TN, TP and TCOD in the effluent were 93%, 90% and 94%, respectively. One-at-a-time (OAT) sensitivity analysis indicated that dominant parameters controlling energy production and consumption include temperature, wastewater influent COD, and electric efficiency of combined heat and power (CHP) engine. The LEM treatment scheme reached a break-even point (energy-self-sufficiency) at 544 mg/L COD and 38% electric efficiency of the CHP engine. The OAT analysis was further expanded using global sensitivity analysis (GSA) techniques to identify the within parameter interactions. The GSA revealed CHP efficiency has a predominantly linear (non-interacting with other inputs) impact on the net energy requirement and has the potential to be a very good control parameter in achieving energy self-sufficiency. In addition, a solution space for energy-positive operation was also identified in this study where minimum non-linear interaction between input parameters is present. Therefore, operating the treatment plant within this linear region ensures maximum control over net energy requirement, while staying within the energy positive range. The results of this study will provide guidance for researchers, municipalities, government agencies and decision-makers, and other stake-holders in choosing the most appropriate P removal option that offer the possibility to move wastewater treatment towards a sustainable, energy- and resource-positive direction.
