Abstract: A system for removing PFSAs and PFCAs from contaminated water using regenerable anion exchange resins includes at least one first anion exchange resin vessel which receives a flow of water contaminated with PFSAs and PFCAs. A first anion exchange resin vessel includes a first regenerable anion exchange resin therein which removes a majority of the PFSAs from the flow of water contaminated with PFSAs and PFCAs and produce a flow of water having a majority of the PFSAs removed. A second anion exchange resin vessel receives the flow of water having a majority of the PFSAs removed. The at least one second anion exchange resin vessel includes a second regenerable anion exchange resin therein which removes a majority of the PFCAs from the flow of water having a majority of PFSAs removed and produce a flow of treated water having a majority of the PFSAs and PFCAs removed.

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. The at least one first anion exchange resin vessel includes a first regenerable anion exchange resin therein having a high affinity for long-chain PFAS compounds configured such that a majority of the long-chain PFAS compounds sorb to the first regenerable anion exchange resin to remove a majority of the long-chain PFAS compounds from the contaminated water and produce a flow of water having a majority of the long-chain PFAS compounds removed. The system also include at least one second anion exchange resin vessel configured to receive the flow of water having a majority of the long-chain PFAS compounds removed.

Abstract: A sustainable system for removing and concentrating per- and polyfluoroalkyl substances (PFAS) from water. The system includes an anion exchange vessel having a selected anion exchange resin therein configured to remove PFAS from the water. A line coupled to the vessel introduces a flow of water contaminated with PFAS such that the PFAS bind to the selected anion exchange resin and are thereby removed from the water. A regenerant solution line is coupled to the anion exchange vessel to introduce an optimized regenerant solution to the anion exchange vessel to remove the PFAS from the anion exchange resin, thereby regenerating the anion exchange resin and generating a spent regenerant solution comprised of the removed PFAS and the optimized regenerant solution. A separation and recovery subsystem recovers the optimized regenerant solution for reuse and separates and concentrates the removed PFAS.

Abstract: A system for pretreating a flow of a liquid contaminated with per- and polyfluoroalkyl substances (PFAS) and at least one precursor. The system includes a preoxidation subsystem configured to receive the flow of liquid contaminated with PFAS and at least one precursor and configured to convert a majority of at least one precursor into PFAS to produce a flow of liquid having the PFAS and the at least one precursor converted to PFAS therein. At least one vessel including an adsorptive media therein is configured to receive the flow of liquid having the PFAS and the at least one precursor converted to PFAS, the adsorptive media configured to remove a majority of the PFAS and a majority of the at least one precursor converted to PFAS and produce a flow of treated liquid having the majority of the PFAS and the majority of the at least one precursor converted to PFAS removed.

Abstract: A system for separating competing anions from per- and polyfluoroalkyl substances (PFAS) in a flow of water contaminated with PFAS and elevated levels of competing anions that includes a separation subsystem which receives the flow of water contaminated with PFAS and elevated levels of competing anions and separates competing anions from the PFAS and concentrates the PFAS to produce a treated flow of water having separated competing anions therein and a flow of water having a majority of PFAS therein. At least one anion exchange vessel having an anion exchange resin therein receives the flow of water having a majority of PFAS therein and removes PFAS from the water to produce a flow of treated water having a majority of the PFAS removed. The separation of competing anions by the separation subsystem increases the treatment capacity of the anion exchange resin to remove PFAS from the contaminated water.
