Polyferric sulfate is a kind of inorganic polymer flocculant with good effect. It is widely used in water treatment industry, especially in industrial wastewater treatment and drinking water purification.

At present, there are two kinds of polyferric sulfate in the market: solid and liquid. The solid polyferric sulfate is light yellow powder solid, and the liquid polyferric sulfate is yellowish brown transparent liquid. The chemical properties of PFS are very stable at normal temperature. As long as the storage method is correct, PFS will not deteriorate. Solid polyferric sulfate has strong water absorption, slight moisture and will not deteriorate.

In wastewater treatment, the solid PFS needs to be dissolved first, and then added to the wastewater. After the PFS is added, the reaction speed of the wastewater is fast, the formed alum is large, the precipitation efficiency is high, and the turbidity of the effluent is low. Polyferric sulfate has little corrosiveness, little harm to equipment, small dosage and low cost.

Polyferric sulfate can be used to treat all kinds of wastewater, no matter the pollution concentration is high or low, it can have a good treatment effect. PFS can adapt to the raw water with pH value of 4-14, and the best effect is at pH value of 6-8.

Like most water purification agents, PFS needs to go through laboratory test before use. After obtaining reasonable use steps and dosage, a reasonable use method is made according to the actual situation.
