CAS No.: 1327-41-7
Molecular formula: [Fe2(OH)n(SO4)3-n/2]m (n<2, m=f(n))
Technical standard: GB14591-2006
Polyferric sulphate(PFS) is Light yellow or Brown amorphous powder.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.
- High effective inorganic salt
- Used for Potable/industrial/waste water treatment
- Better effect for COD, BOD remove
- Competitive price
