This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a research project conducted at Colorado State University (CSU) to evaluate the impact of backwash recycling on water treatment plant performance. The main focus of the project was to conduct a series of experiments using the CSU pilot water treatment plant under different operational scenarios of steady-state and surge spent backwash water recycling. Each experiment entailed a control (non-recycle) run immediately followed by an experimental (recycle) run. On-line instruments and laboratory analysis of grab samples were used to evaluate the effect of spent backwash water recycling on filter effluent quality and filter run time for both conventional and direct filtration processes. During the period of pilot testing, nearly one hundred separate filter runs were performed. After pilot testing was completed, water sampling was conducted at a full-scale conventional filtration plant located in Colorado. Plant personnel modified the backwash recycle operation over a period of four weeks to include steady-state and surge backwash recycling, and to run the plant for brief periods without recycling. Grab samples and instrumentation data, obtained during this period of modified operation, were analyzed at CSU to evaluate the effects of recycling at an operating water treatment plant (WTP) and to assess transferability of the pilot-scale data to full-scale operations. Analysis of pilot- and full-scale data suggested that total suspended solids (TSS) could be a useful indicator of the process mass balance and filter performance. Using TSS data obtained from grab samples, additional research was conducted to quantify mass loading of the filters during recycle/nonrecycle runs and to evaluate the ability of TSS measurements to predict filter run time breakthrough. m̀stances, the mi.

Available in PDF, EPUB and Kindle. Book excerpt: Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.

Download or read book Guidance Manual for Coagulant Changeover written by James DeWolfe and published by American Water Works Association. This book was released on 2003 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual is a source document for utilities that are considering a coagulant changeover. It is intended to provide an appreciation of what must be considered for a successful changeover based on the input of U.S. and Canadian utilities (Chapters 1 and 6). New regulatory requirements will likely have the broadest and most substantial impact on primary coagulant use (Chapter 3). The Interim Enhanced Surface Water Treatment Rule (IESWTR) and Stage 1 Disinfectant and Disinfection Byproducts Rule (Stage 1 DBPR) will make finished water requirements more stringent to address microbial removal and the impacts of disinfection. Enhanced Coagulation and/or other operational and treatment practices will be used to achieve these requirements. The science of coagulation (Chapter 4) requires a special focus to address the intricacies of coagulation chemistry. The manual provides a step-by-step methodology to conduct a coagulant changeover using a detailed protocol (Chapter 5) -- background, executive summary.

Download or read book Interface Science in Drinking Water Treatment written by Gayle Newcombe and published by Academic Press. This book was released on 2006-09-06 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is difficult to imagine anything more important to the human population than safe drinking water. Lack of clean drinking water is still the major cause of illness and death in young children in developing countries. In more fortunate communities, where water treatment is practiced, the primary aim of water authorities is to provide water that is free from pathogens and toxins. Most countries now have water quality regulations, or guidelines, which are driving water authorities to produce purer water, with the minimum of contamination from natural or man-made origin. At the same time, consumers are demanding that chemicals added during the treatment of drinking water be kept to a minimum. As a consequence, conventional clarification methods are being challenged to comply with the new regulations and restrictions and our understanding of the mechanisms involved is being tested as never before. Interface Science in Drinking Water Treatment contains a rigorous review of water treatment practices from a fundamental viewpoint. The book includes material from leading experts in the field of water treatment, reviewing their specific fields of expertise against a background of colloid and surface chemistry, and examines each step of the journey from source to consumer tap. It therefore permits the reader to develop a deep understanding of the complex processes taking place and of the necessary treatments which are vital for the provision of safe and palatable drinking water. The book is aimed at researchers, educators and practitioners in science and engineering, particularly those involved in water treatment and colloidal chemistry. - Covers all existing water treatment processes, approached from a fundamental surface and colloid science viewpoint - Unique collection of R&D authors, all experts in water treatment processes - Comprehensive review of water treatment with a complete list of references
