Poly ferric sulfate (PFS) is a polyhydroxy, combination of multi-core, cationic polymeric inorganic flocculant. It can be quickly mixed with water at any ratio. The solution contains large amount of ferric iron and ferrous iron like (Fe2(OH)3)3+, (Fe3(OH)6)3+, (Fe8(OH)28)4+, which has larger molecular weight than other inorganic coagulant.

Poly ferric sulphate application

1. Drinking water and sanitary sewage.
2. Industrial water, industrial waste water, mine and water for oilfield injection, chemical waste water in industry of paper-making, metallurgy, washed coal and leather.
3. Industry and makes waste water recyclable: paper-making glue, printing and dying, concrete hardener, precision casting hardener, glycerine refinement, crease-resistant for fabric, medicine, cosmetics and etc.
4. Oil-water separation and has good effects in the oil refining industry.



Poly ferric sulphate use method

1. Solution Preparation: The dissolve rate of PFS is 5%. It means dissolve 50g PFS into 1L water. The water is tap water or purified water.

2. Dissolve Time: The time is 5-10 min if you fully stir for dissolve.

3. Dosage: Get water sample and confirm optimum dosages by test.
