How to Get PFAS Out of Drinking Water--and Keep It Out

Dr. Poole notes there are three methods for removing PFAS components from water: reverse osmosis through a semipermeable membrane (which is energy intensive), activated carbon filtration (like that done with water pitchers), and ion exchange. With the first two methods, the captured material (here, PFAS compounds) can leach out of disposed materials and re-enter the environment. With ion exchange, the captured substance can be deliberately washed out and destroyed, and the ion exchange substrate re-activated and reused.

They are examining the use of zeolites (naturally occurring minerals) as the ion exchange substrate, getting good results and finding the removal of adsorbed PFAS and regeneration of the zeolites is easily done. Methods exist to decompose recovered PFAS compounds, with heat and pressure.

They apparently plan to market pitcher filters using this technology. The company name is Epic Water Filters. Consumers will be able to return spent filters to the company for recovery.
