Use of BDST Analysis Techniques for the Design of Filtration Systems Using Coarse Media and Dual Media Filters in Series

Abstract

In the last two decades, filtration research has significantly increased the hydraulic capacity and particulate removal capacity of deep bed filters. The use of dual media, multimedia, and coarse media filters in conjunction with improved chemical pretreatment using polymers to enhance the attachment of suspended particles to the filter media have made longer filter runs at higher filtration rates practical and economical.
