PFS (poly ferric sulphate)
PFS(poly ferric sulphate), light yellow powder or deep red liquid, is a kind of inorganic high polymer flocculating agent, which features are high density of alumen ustum, high speed of precipitation,high rate of pollution removal and low amount of sewage sludge, and etc.
The product is in great demand on all kinds of municipal sewage treatment and industrial wastewater treatment, which includes electronics, papermaking, dyeing, electroplating, meat packing plant, food processing, smelting, etc. As to the industry of electronics and electroplating, it displays high removal rate of COD and high speed of precipitation.

1.Add suitable amount of PFS to wastewater and then stir evenly.
2.The amount of PFS is proportional to the polluting extent of wastewater, commonly 15-50 kilograms dosage to 1000ton wastewater.
3.Before using PFS,adjust pH value 7~10, one way is to add some alkali.
