Many municipalities discovered that levels of perfluorinated and poly-fluorinated substances in their water systems exceed new Federal Health Advisory levels. These chemicals are collectively known as PFASs and are commonly referred to as PFAS. Although the current health advisory levels vary throughout the world, in May 2016, the US EPA issued Health Advisory (HA) levels of 70 parts per trillion (ppt) for two of these chemicals, PFOS and PFOA (perfluorooctane sulfonic acid and perfluorooctanoic acid, respectively). When both PFOS and PFOA are present at the same time in the water, the recommended combined health advisory level is 70 ppt.
Purolite has designed, developed and commercially tested a special ion exchange resin with high selectivity for poly- and perfluoroalkyl substances. Purofine® PFA694E resin is a proprietary, uniform particle size resin with the dual removal mechanisms of ion exchange and adsorption technology built into each bead for maximum uptake of PFAS. Water treated with this resin will consistently achieve non-detectable levels of both short- and long chain PFAS—including PFOA, PFOS, PFNA, PFHxA, PFHxS, PFHpA, PFBS and PFBA.
Advantages of Purofine PFA694E:
Perfluoroalkyl Substance Removal (Long Chain)
Perfluoroalkyl Substance Removal (Short Chain)
