Poly Ferric Sulfate

CAS No.:10028-22-5 MF:[Fe2(OH)n(SO4)3-n/2]m   

 EINECS No.:233-072-9    Purity:19%

Wide Range of PH Value
Soluble in water
Excellent effect on water purifying

Poly Ferric Sulfate (PFS)

The product is a kind of high-efficiency inorganic coagulating; its chemical property is stable, soluble in water. In water treatment,it hydrolysis to many electrpositive multinuclear complextion which neutralized surface electric charge of colloidal particale in water and adsorbed colloidal partical, making particles flocculated through adhesion, bridging, crosslinking, then purify water.

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

 

Application
Mainly used in various industrial wastewater treatment, such as paper-making wastewater, municipal wastewater, oily wastewater, beneficiation wastewater, chemical wastewater treatment and so on.

 

Cautions:
1. This product mustn't be stored with other chemical reagents.
2. Solid products should be stored in a ventilated and dry place with the storage period of two years, and the availability won't be changed after the product is affected by damp.
