Poly Ferric Sulfate(PFS)Characteristics Poly Ferric Sulfate (PFS) is a complex ferric material. The molecular formula is

Poly Ferric Sulfate(PFS)


 Poly Ferric Sulfate (PFS) is a complex ferric material. The molecular formula is the [Fe2 (OH)n (SO4)3-N/2]m, n2; m=f (n). There are a lot of complex ferrous ion ([Fe2 (OH)3] 3+ , [Fe(H2O)6] 3+, [Fe3(OH)3] 6+) in it’s water solution. So it is good agglomerate which has easy formation flocculate and have a good coagulation. It chemical structure is a solid network polymer which has a multinuclear complex ion. The easier hydrolysis in water and the highly efficient multinuclear hydroxyl complex negative ion have been produced during hydrolysis. In the process of a water treatment, Polymer ferrous sulfate has a good ability to neutralize surface electric charge of suspended substances, and linking suspended particle.

1. Water purification agent.

2. Industry waste water treatment (such as the paper making waste water, the printing waster water, the massacre waste water, the automobile manufacturing waste water, the beer factory waste water and so on.),

3. Many kinds of industry circulating water treatment (ex, the blast–furnace gas washing water, the make-up water of the high pressure boiler in the heat and power plant, the industry waste water in biochemical treating factory, the waste emulsifying solution, the opalescent solution and the oil waste water.

4. This product is used in environmental protection, industrial wastewater treatment, use and water plant roughly the same, high color, high COD, BOD raw water treatment, supplemented by additives effect is very good.
