Abstract
A system for removing long-chain and short-chain per- and polyfluoroalkyl substances (PFAS) from contaminated water using a regenerable anion exchange resin includes at least one first anion exchange resin vessel configured to receive a flow of water contaminated with long and short-chain PFAS compounds. A first anion exchange resin vessel includes a first regenerable anion exchange resin therein configured such that a majority of the long-chain PFAS compounds are removed by the first regenerable anion exchange resin. A second anion exchange resin vessel receives the flow of water having a majority of the long-chain PFAS compounds removed and includes a second regenerable anion exchange resin and is configured to remove a majority of the short-chain PFAS compounds from the contaminated water and produce a treated flow of water having a majority of the long and short-chain PFAS compounds removed.
