Microfiltration in the RCF Process for Hexavalent Chromium Removal From Drinking Water

This project investigated the effectiveness of microfiltration (MF) as a key component in the reduction/coagulation/filtration (RCF) treatment process for hexavalent chromium removal. Two types were evaluated: pressure polymeric and submerged polymeric. The MF testing results will help utilities to select the proper filtration for their facilities without having to test all of the potential variables that were investigated in this project, thus resulting in cost savings to other utilities. Cost information was developed for these two types of RCF-MF processes to inform the regulatory process and identify limits of treatability. Tailored collaboration partner: Glendale Water & Power.
