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: Systems and methods for treating a wastewater are provided. The wastewater treatment system and methods allows for effective treatment of wastewater during conditions that may cause increased wastewater flow to the system.

Abstract: A ballasted sequencing batch reactor system for treating wastewater including one or more sequencing batch reactors.

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: The present disclosure is directed to systems and methods for removing waste materials from the surface of liquid in a liquid treatment system. In one example a surface wasting system comprises a chamber including a sump, an outer conduit coupled by a first seal to an upper wall of the chamber, an inner conduit axially disposed within the outer conduit, the inner conduit in contact with a surface of a liquid in a treatment vessel of the liquid treatment system, an expandable waterproof bellows having a lower end coupled to the outer conduit above the first seal and an upper end coupled to the inner conduit, the waterproof bellows forming a second seal between the outer conduit and the inner conduit, and a float coupled to the inner conduit and configured to vertically displace the inner conduit responsive to a change in a level of liquid in the sump.
