Sustainability And Safety Considerations For PFAS Removal

While the effectiveness of GAC (granular activated carbon) and IX (ion exchange) as adsorbents for per-and polyfluoroalkyl substances (PFAS) is without question, traditional bulk media systems come with a range of drawbacks that make water treatment plants (WTPs) hesitant to invest in them. Thankfully, there are ways to take advantage of PFAS removal without installing bulk media systems. As the U.S. EPA considers plans to list nine PFAS as hazardous substances under Resource Conservation and Recovery Act (RCRA), now is the time for WTPs to examine the health, safety, and sustainability considerations of PFAS removal cartridge technology.

PFAS removal cartridges have three main advantages over other technologies. The first is the ease of changeouts compared to bulk media. The second is the eco-friendlier disposal options. The third is the more compact footprint. This article will discuss all three areas in detail.
