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.
