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 2019-10-21 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Need of water purification was realized by man in early stages of civilization. So, Central and State Government are making efforts to provide adequate and safe drinking water to the people by constructing water treatment plants in the country. Filtration process under goes degradation at initial and last phase which affect the initial effluent quality of filtrate after back washing. The rapid sand filter is important unit of water treatment plant which removes the flocs and colloids through filtration After backwash filter when rapid sand filter brought back in to normal operation high initial turbidity of filtrate is observed. It is in the form of turbidity spike. To reduce this turbidity spike filter conditioning is essential. The present study is for rapid sand filter conditioning using coagulants as alum and polymer in different percentage during backwash of rapid sand filter. The optimal dosage as well as corresponding points of application during backwash will be determined based on laboratory scale studies which found to be improved in initial effluent quality of rapid sand filter.

Download or read book Assessment of Auxiliary Backwash Methods for Rapid Sand Filters written by Richard C. Pohlman and published by International Water Assn. 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.
