Basic info

English name: Polymeric ferric sulfate short for PFS

CAS No.: 1327-41-7

Molecular formula: [Fe2(OH)n(SO4)3-n/2]m (n<2, m=f(n))

Technical standard: GB14591-2006

Features PFS:

Appearance: Light yellow /Brown amorphous powder. Polyferric sulfate(PFS) is a high-efficiency inorganic coagulating agent, chemically inactive, soluble in water. 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: Polyferric sulfate(PFS) Mainly used on various industrial effluent treatment plants, such as electroplating wastewater, paper-making wastewater, municipal wastewater, oily wastewater, dye wastewater and chemical wastewater treatment and so on.
