Polyferric 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 a large amount of ferric iron and ferrous iron-like (Fe2(OH)3)3+, (Fe3(OH)6)3+, (Fe8(OH)28)4+, which has a larger molecular weight than other inorganic coagulants.

PFS Feathures
- The purify function is unaffected by temperature fluctuations, and it can be used in different climate zone
- It overcomes the common problem of water treated by other flocculant iron salts – highly corrosive and high chroma.
- The dosage is lower and it reduces the over all water treatment cost.
PFS Applications
- Drinking water treatment
- Waste water and industrial waste water treatment
- Coal washing water treatment, and any water with high content of COD
- It is safe and non-toxic and proved by tests
