Download or read book Assessment of Auxiliary Backwash Method for Rapid Sand Filters written by Richard C. Pohlman and published by American Water Works Association. 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.

This book was released on 2006 with total page 84 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Water Filtration Practices written by Gary S. Logsdon and published by American Water Works Association. This book was released on 2011-01-12 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water operators will find a wealth of hands-on information on the operation and maintenance of pretreatment, rapid-rate granular media filtration, slow-sand filtration, and diatomaceous-earth filtration systems in this book. This practical guide provides recommended procedures for operating, monitoring, and maintaining all types of filters used for conventional water treatment. These procedures are tested and time-proven by hundreds of water utilities and filtration experts to provide high filter efficiency, excellent water quality, long filter runs and minimum downtime. The book also gives advice on what not to do-and why-so you can avoid water quality problems, filter damage, and treatment problems in the future.
