This book was released on 2006 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this project was to determine differences in filter effluent water quality and media cleanliness between sand filters employing air scour and those employing surface wash. Discussed in detail are the findings that scour and surface wash systems performed similarly relative to filter effluent quality and filter cleanliness. The advantages of one system over another can be site-specific particularly in retrofit applications.

Book excerpt: An audit was performed in 1996 and 1998 at GCWW;s Richard Miller Treatment Plant (RMTP) to insure compliance with all current and proposed state and federal maximum contaminant levels. During the audit, training in filter profiling, including coring and floc retention analysis, was provided. Through these techniques, GCWW determined that the filter media was not getting effectively cleaned. Auxiliary backwash was recommended, but no experimental protocol was available to choose among available options. Four filters at RMTP were rebuilt for this study. New Leopold dual parallel lateral type block underdrains with integral media support (IMS) caps were installed. The sand media was completely replaced. Two filters were outfitted with air scour, one with surface wash and one was rebuilt with no auxiliary wash. The backwash procedures were then optimized and standardized before initiating the study. Turbidity and microbial testing were performed at various time intervals throughout the filter run to characterize the quality of the filter effluent. The magnitude and duration of the initial solids breakthrough were determined by the use of continuous turbidimeters and a supervisory control and data acquisition (SCADA) system. Filter cores and floc retention analyses were used to determine the filter media cleanliness.

Available in PDF, EPUB and Kindle. Book excerpt: An In-Depth Guide to Water and Wastewater Engineering This authoritative volume offers comprehensive coverage of the design and construction of municipal water and wastewater facilities. The book addresses water treatment in detail, following the flow of water through the unit processes and coagulation, flocculation, softening, sedimentation, filtration, disinfection, and residuals management. Each stage of wastewater treatment--preliminary, secondary, and tertiary--is examined along with residuals management. Water and Wastewater Engineering contains more than 100 example problems, 500 end-of-chapter problems, and 300 illustrations. Safety issues and operation and maintenance procedures are also discussed in this definitive resource. Coverage includes: Intake structures and wells Chemical handling and storage Coagulation and flocculation Lime-soda and ion exchange softening Reverse osmosis and nanofiltration Sedimentation Granular and membrane filtration Disinfection and fluoridation Removal of specific constituents Drinking water plant residuals management, process selection, and integration Storage and distribution systems Wastewater collection and treatment design considerations Sanitary sewer design Headworks and preliminary treatment Primary treatment Wastewater microbiology Secondary treatment by suspended and attached growth biological processes Secondary settling, disinfection, and postaeration Tertiary treatment Wastewater plant residuals management Clean water plant process selection and integration

This book was released on 2018-07-27 with total page 994 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides an excellent balance between theory and applications in the ever-evolving field of water and wastewater treatment Completely updated and expanded, this is the most current and comprehensive textbook available for the areas of water and wastewater treatment, covering the broad spectrum of technologies used in practice today—ranging from commonly used standards to the latest state of the art innovations. The book begins with the fundamentals—applied water chemistry and applied microbiology—and then goes on to cover physical, chemical, and biological unit processes. Both theory and design concepts are developed systematically, combined in a unified way, and are fully supported by comprehensive, illustrative examples. Theory and Practice of Water and Wastewater Treatment, 2nd Edition: Addresses physical/chemical treatment, as well as biological treatment, of water and wastewater Includes a discussion of new technologies, such as membrane processes for water and wastewater treatment, fixed-film biotreatment, and advanced oxidation Provides detailed coverage of the fundamentals: basic applied water chemistry and applied microbiology Fully updates chapters on analysis and constituents in water; microbiology; and disinfection Develops theory and design concepts methodically and combines them in a cohesive manner Includes a new chapter on life cycle analysis (LCA) Theory and Practice of Water and Wastewater Treatment, 2nd Edition is an important text for undergraduate and graduate level courses in water and/or wastewater treatment in Civil, Environmental, and Chemical Engineering.
