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.

Abstract: A system for removing PFAS from a solution having PFAS therein using foam fractionation is featured. The system includes at least one first foam fractionation subsystem including a vessel configured to receive the solution having PFAS therein and configured to generate microbubbles, turbulence, and foam to remove a majority of the PFAS and generate a treated solution and a flow of foam having the removed PFAS therein. The system also includes a heating and dehumidification subsystem coupled to the at least one foam fractionation subsystem and configured to generate a flow of heated dehumidified gas. The at least one foam fractionation subsystem is configured to output the flow of foam having the removed PFAS therein into the flow of heated dehumidified gas such that the flow of a heated dehumidified gas collapses the flow of foam having the removed PFAS therein into a flow of liquid having the removed PFAS therein.
