Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powder solid, easily soluble in water, and its 10% (mass) aqueous solution is reddish brown transparent solution with hygroscopicity.

Polyferric sulfate is widely used in the purification of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dewatering, oilfield wastewater and domestic sewage.

Compared with the simultaneous interpreting agent, ferrous sulfate or aluminum sulfate, polymeric ferric sulfate has the following characteristics:

First, the dosage was small;

Second, it has strong adaptability and can get good results for all kinds of water quality conditions;

Third, it is not necessary to change the pH value of raw water basically;

The fourth is fast flocculation, large alum and rapid sedimentation;

Fifth: it can decolorize, remove bacteria, remove radioactive elements, remove heavy metal ions, and reduce COD and BOD.

The combined use of PFS and PAM for reinjection treatment of oilfield produced water has better treatment effect than that of aluminum sulfate and polyaluminum chloride. Generally, 50-80mg / l can be added to oily wastewater treatment.

As PFS has superior water purification performance, it can adapt to the raw water with many changes and impurities, and basically has no adverse effect on human health, the demand will be increasing. As long as the quality of the product meets the requirements, the market prospect is broad, and the product has simple manufacturing process, low production cost and strong competitiveness in price.
