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.

Abstract: A system for enhancing adsorption of contaminated vapors to increase treatment capacity of a regenerable, synthetic adsorptive media. The system includes an inlet configured to receive a flow of contaminated vapors. One or more vessels are coupled to the inlet, the one or more vessels each including a regenerable, synthetic adsorptive media therein, are configured to remove contaminants from the vapors by adsorption. A vapor cooling subsystem is coupled to the inlet, and configured to cool the flow of contaminated vapors, thereby increasing the treatment capacity of the regenerable synthetic adsorptive media.

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 includes 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. The at least one second anion exchange resin vessel includes a second regenerable anion exchange resin therein having a high affinity for short-chain PFAS compounds and is configured such that a majority of the short-chain PFAS compounds sorb to the second anion exchange resin 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.

Abstract: A sustainable system for removing and concentrating per- and polyfluoroallcyl 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 MBR system for removing PFAS from a flow of wastewater and/or landfill leachate includes an MBR which receives the flow of wastewater and/or landfill leachate having PFAS therein. An impregnation subsystem receives a flow of mixed liquor from the MBR and a predetermined amount PAC to maintain a predetermined ratio of PAC to biomass in the MBR and blends the biomass with the PAC to form PAC-impregnated biological flocs. An outlet coupled to impregnation subsystem outputs a flow of PAC-impregnated biological flocs to the MBR such that the PAC-impregnated biological flocs in the MBR adsorb to and remove a majority of the PFAS from the flow of wastewater and/or landfill leachate and the MBR outputs a flow of treated wastewater and/or landfill leachate having a majority of the PFAS removed.
