Abstract

See full text

Disclosed is a method for enhancing the removal of a per- and polyfluoroalkyl substances (PFAS) component from waste water using a cationic polymer (e.g., a cationic polymer flocculant or coagulant). The cationic polymer enables gas that is diffused through the waste water to carry at least a portion of the PFAS component to the surface of water, creating a foam that can then be removed.
