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: 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.

Download or read book Factors Influencing the Reliability of Enhanced Biological Phosphorus Removal written by J. B. Neethling and published by IWA Publishing. This book was released on 2006-03-31 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enhanced biological phosphorus removal (EBPR) has been used for decades to remove phosphorus from municipal wastewater because it allows facilities to meet water quality goals while minimizing chemical consumption and sludge production. However, there is still substantial variability in both the practices applied to achieve EBPR and the level of soluble phosphorus removal achieved. The objective of this research project was to develop information that can be used to help municipal wastewater treatment plants more efficiently and cost effectively remove phosphorus through EBPR processes. This project included detailed analysis of routine water quality and operating data, field testing observations, and special studies conducted over the course of the project to evaluate the variability of EBPR, factors influencing EBPR performance, and the relationship between EBPR and the presence of glycogen accumulating organisms (GAOs).

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.

This book was released on 2021 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Anaerobic-anoxic-oxic (A2/O) is one of the most widely used processes in municipal wastewater treatment plants for simultaneous biological nitrogen and phosphorus removal. The A2/O process has many advantages, such as simple configuration and short hydraulic retention time (HRT), etc. In addition, it is easy to operate. Therefore, A2/O will be continuously chosen as the main option in all kinds of newly designed and built wastewater treatment plants. Though the A2/O process has been used widely, it has some inherent contradictions which are difficult to overcome. For example, the contradiction between substrate competition and SRT makes the high nitrogen and phosphorus removal unable to be achieved simultaneously. As a result, the removal efficiency of the system cannot be further improved. In the past 10 years in China, the wastewater quality very obviously changed with the improvement of living conditions. At present, municipal wastewater with a low C/N ratio is rather common in most countries in the world. The lack of a carbon source will make the inherent contradictions of the A2/O process becomes serious. Therefore, the conventional design parameters of the A2/O process are needed to adjust or the configuration of the A2/O process should change to fit the change of the wastewater quality. According to this, this book systematically describes how to improve the nitrogen and phosphorus removal efficiency of municipal wastewater with low C/N ratio, and effectively utilize the carbon resource in the influent of wastewater. This publication is useful for students, researchers and engineers whose major focus is municipal and the environment"--
