  • Patent number: 11679999
    Abstract: A method for the decontamination of water containing one or more PFAS, having the steps of generating colloidal gas aphrons (CGAs) by mixing a gas, water, and one or more surfactants together with high shear forces, introducing the CGAs and a PFAS-containing water in an enclosed space where the CGAs move upwards through the water due to their inherent buoyancy, allowing the plurality of CGAs to extract PFAS from the water, and separating the PFAS-containing CGAs from the surface of the water in the enclosed space for further treatment or disposal, leaving the water with lower PFAS concentrations in the vessel. The aphrons may be anionic or cationic and created by mixing speeds or surfactant concentration, and treatment may be with gas bubbles to remove PFAS from water gas bubbles or destruction of PFAS by plasma reactor or deployed in situ through wells into geologic ground formations.
    Type: Grant
