    Corrosionpedia What is a Coagulant Aid? Definition

    A coagulant aid is a chemical or material, which is not a coagulant, used to assist or modify coagulation. Coagulant aids add density to slow-settling flocs and add toughness to the flocs so that they do not break up during the mixing and settling processes. A coagulant aid improves the effectiveness of a coagulant by:
