A PROCESS FOR REMOVAL OF PFAS FROM WATER

Publication number: 20220298029

Abstract: A method for removing PFAS from a PFAS-containing aqueous phase, comprising adding to said aqueous phase a surfactant composition comprising at least one cationic surfactant, to allow the surfactant to form micelles in said aqueous phase, and bringing said micelle-containing aqueous phase in contact with an ultrafiltration membrane under pressure, to obtain a permeate flow aqueous phase having a reduced concentration of PFAS.
