Abstract: PFAS (Per- and polyfluoroalkyl substances) contained in water are remediated by a process in which colloidal as aphrons (CGAs) are generated under shear and with surfactants, either added to the liquid or inherent in the PFAS. Preferably a pump is used to generate the CGAs, to move CGAs and liquid through the system, and to induce gas or air into the pump. The resulting foam that rises to the surface is comprised of various small bubbles, producing a very large surface area effective in attracting PFAS by surface adsorption, and when the foam is removed a small volume of liquid highly concentrated in PFAS can be efficiently destroyed by various known destruction techniques. The method is effective to remove PFOS.
