Poly ferric sulfate(PFS) is a high-efficient inorganic coagulating agent. In water treatment, it hydrolysis to many electropositive multinucleated ion which neutralized negative charge of colloidal particle in water and adsorption colloidal particle, through adhesion, bridges, cross-linking made particles flocculation and sedimentation.
Application:
Mainly used in various industrial wastewater treatment, such as paper making, municipal wastewater, oil field wastewater, mineral processing and so on.
