Available in PDF, EPUB and Kindle. Book excerpt: The report documents a study to develop a treatment system for combined sewer overflows. The processes of chemical oxidation, screening, dissolved-air flotation, and disinfection were evaluated in the laboratory. A 5 MGD demonstration system was designed, installed and evaluated. Suspended solids and volatile suspended solids removal in the range of 65-80% were consistently obtained at influent concentrations of 150 to 600 mg/l. BOD and COD removals were slightly lower at 55 to 65% for influent concentrations of 50 to 500 mg/l. Addition of chemical flocculents (ferric chloride and a cationic polyelectrolyte) was necessary to obtain these removals. Without the use of chemical flocculents, removal of BOD, COD, suspended solids, and volatile suspended solids were all in the range of 40-50%. The screening flotation system provided sufficient detention time (difference 15 minutes) for adequate disinfection with hypochlorite salts. Cost estimates are presented.

This book was released on 1997-08-29 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control and Treatment of Combined Sewer Overflows Second Edition Edited by Peter E. Moffa In cities where storm and sanitary sewers are operated as one system, storm runoff overflows remain the most common potential source of untreated human waste in the water supply—and the single biggest obstacle to achieving the swimmability goals of the 1972 Clean Water Act Amendments. Communities upgrading old systems in order to provide safe, EPA-compliant water to their growing populations face both logistical and financial challenges. Yet, in the last decade significant advances in combined sewage overflow (CSO) abatement have been realized. The National CSO Control Strategy was published in 1989, with the final CSO policy approved in 1994. The EPA has intensified research and development; receiving-water impacts have been quantified; more cost-effective plans, prototypes, and facilities have been tested and implemented; and the water supplies in over a dozen U.S. cities are showing dramatically diminished CSO pollution levels. This revised edition of Control and Treatment of Combined Sewer Overflows takes into account recent advances in research, planning, and practice to be the single most authoritative and up-to-date resource on CSO abatement. Written by expert CSO consultant Peter Moffa and a contributing team of top engineers, the book provides both the mathematical and analytical tools necessary for modeling current sewer systems and developing workable CSO abatement strategies. Control and Treatment of Combined Sewer Overflows, Second Edition Features: A condensed overview of federal CSO policy (watershed) Guidelines for minimum control, long-term control planning, screening and ranking, project funding, CSO monitoring and modeling, and performance measurement Fully updated discussions of mathematical models for combined sewer systems A wide range of practical control and treatment technology systems—many developed since 1989, and Recent Case Studies—a complete section on cost-effect analysis showing how a number of U.S. cities enact effective storage, abatement, and disinfection plans. This edition features new case studies on Rouge River, Charlotte, NC, and Decatur, IL, plus updated reports from Onondaga County, NY, and Washington, DC. Control and Treatment of Combined Sewer Overflows, Second Edition is an essential reference for wastewater and sanitary engineers, as well as city planners and administrators responsible for wastewater treatment. It is also the ideal textbook for advanced undergraduate and graduate students in wastewater and environmental engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Control and/or treatment of stormwater discharges and combined sewage overflows from urban areas are problems of increaseing importance in the field of water quality management. Over the past decade much research effort has been expended and a large amount of data has been generated, primarily through the actions and support of the U.S. Environmental Protection Agency's (EPA) Storm and Combined Sewer Research and Development Program. Presented in this text are selected results of a comprehensive investigation and assessment of promising, completed and ongoing projects, representative of the state-of-the-art in abatement theory and technology; a look at recent legislation; and the identification of program needs and emphasis. Combined sewer overflows are major sources of water pollution problems, but even discharges of stormwater alone can seriously affect water quality. Current approaches involve control of overflows, treatment and combinations of the two. Control may involve maximizing treatment with existing facilities, control of infiltration and extraneous inflows, surface sanitation and management, as well as flow regulation and storage. A number of treatment methods have been evaluated including high rate screening and microstraining, ultra high rate filtration, dissolved air flotation, physical/chemical treatment, and modified biological processes. A swirl flow regulator/solids separator of anular shape construction with no moving parts has been developed. High rate disinfection methods including new disinfectants have been applied. Promising approaches involve integrated use of controls and treatment. The most disappointing have generally lacked flexibility in their operation and design. Mathematical models have been developed and successfully applied at multiple levels of sophistication and complexity.
