Specification :

Poly Ferric Sulfate, PFS is a high-efficiency unorganic 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.

Performance:
1. rapid sedimentation, good flocculation.
2. Excellent effect on water purifying., remarkable function on decoloration deodorization, dehydration, deoiling, sterilization, removal of heavy metal ions in water, radioactive substances and carcinogens, strong ability to remove COD, BOD.
3. Stable property, it' s solution can long-term storage.
4. It has wide range of PH Value: from 4-11, when 6-9 is best.The PH Value changes very little after water treatment, and reduce the hardness of water.

Use:
Mainly used on various industrial wastewater treatment, such as paper-making wastewater, municipal wastewater, oily wastewater, beneficiation wastewater and chemical wastewater treatment.
