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 carbon dioxide from a flow of gas having carbon dioxide therein is featured. The system includes a first venturi eductor and first reactor which receive the flow of gas having carbon dioxide therein and a flow of a first alkaline solution at a first predetermined pH range. The first venturi eductor and reactor mix and provide reaction time for the flow of gas having carbon dioxide therein and the flow of the first alkaline solution to induce a reaction of the carbon dioxide with the first alkaline solution to form a solution having metal bicarbonate therein. A second venturi eductor and reactor mix the flow of the partially treated gas with the flow of the second alkaline solution and provide reaction time to react a majority of the remaining carbon dioxide with the second alkaline solution to form a solution having metal carbonate therein.

Abstract: A system for removing carbon dioxide from flow of gas having carbon dioxide including a venturi eductor configured to receive the flow of gas having carbon dioxide therein and a flow of an alkaline solution at a predetermined pH range. The venturi eductor is configured to introduce and mix the flow of gas having carbon dioxide therein into the flow of the alkaline solution to induce the transfer of the carbon dioxide into a carbonic acid solution and the subsequent conversion of the carbonic acid solution into a solution having metal carbonate therein. A reactor is coupled to the venturi eductor includes a volume of the alkaline solution and is configured to provide sufficient reaction time to augment the transfer of carbon dioxide into the carbonic acid solution and the subsequent conversion of the carbonic acid solution into a solution having metal carbonate therein and output a flow of treated gas having a majority of the carbon dioxide removed. A pump coupled to the reactor is configured to recycle the flow of alkaline solution from the reactor to the venturi eductor such that the venturi eductor introduces and mixes the flow of gas with the flow of the alkaline solution. An output is coupled to the reactor and is configured to output a flow of a solution having metal carbonate therein to minimize the formation of metal carbonate precipitate in the reactor. A pH adjustment subsystem is configured to maintain the pH of alkaline solution at the predetermined pH range.

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 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.
