The 1-1 ---- system includes an anion exchange vessel having a selected anion exchange resin therein configured to remove PFAS from the wa - 1r---- ter. A line coupled to the vessel introduces a flow of water contaminated with PFAS such that the PFAS bind to the selected anion 1-1 C exchange resin and are thereby removed from the water. A regenerant solution line is coupled to the anion exchange vessel to intro - N duce an optimized regenerant solution to the anion exchange vessel to remove the PFAS from the anion exchange resin, thereby re - 0 generating 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.
