Multi-Contaminant Removal With Granular Activated Carbon (GAC) In Drinking Water Filtration

Due to increasing regulations and an ever-rising understanding of contaminants present in many drinking water sources, water treatment plants (WTPs) are more frequently tasked with addressing multiple contaminants. To many engineers and WTP managers, having to remove one or more new contaminants often means adding multiple, targeted filtration systems. However, it is possible for a single system to be a multi-contaminant solution.

For years, the U.S. EPA has recognized granular activated carbon (GAC) as a best available technology (BAT) for a wide range of substances, many of which can be addressed within the same system. It is proven to be a highly effective solution for removing total organic carbon (TOC), disinfection byproducts (DBPs), 1,2,3-tricholoropropane (1,2,3-TCP), taste and odor (T&O), volatile organic compounds (VOCs), algal toxins, and per- and polyfluoroalkyl substances (PFAS).
