Polyferric sulfate(FPS) is a new water purification agent. If you want to achieve the expected effect, the precautions for the use of polyferric sulfate are one of the basic knowledge that people must know. At present, Polyferric sulfate is mostly brown powder, which needs to be dissolved before use. The fully dissolved Polyferric sulfate is generally a reddish brown liquid, which can be exchanged with water to a certain concentration of aqueous solution. When in use, put an appropriate amount of Polyferric sulfate solution into the sewage. After stirring evenly, alum will form, gradually become larger and begin to settle. About 20 minutes, all alum will settle to the bottom, and the sewage will become clear. The appropriate input of polymeric ferric sulfate needs to be obtained through small-scale experiments. Appropriate adjustments shall be made according to the actual situation to ensure the use effect of polymeric ferric sulfate.


If the amount of Polyferric sulfate solution prepared first is used up, it will deteriorate. Polyferric sulfate is slightly corrosive, so certain anti-corrosion measures are required for both manual use and treatment equipment. Polyferric sulfate can be used with polyacrylamide and other organic coagulants, but can not be used with inorganic coagulants.

Polyferric sulfate is a new, high-quality and efficient ferric salt water purification flocculant. At present, it is widely used in industrial wastewater treatment, and the effect is also very good. Polyferric sulfate has strong functions of turbidity removal, decolorization, oil removal, dehydration, COD removal and heavy metals in industrial wastewater treatment. Therefore, polyferric sulfate is widely used in various industrial wastewater treatment such as printing and dyeing wastewater, electroplating wastewater, papermaking wastewater and pharmaceutical wastewater.


Polyferric sulfate can replace polyaluminium chloride and other water purification agents in industrial wastewater treatment. The wastewater treated with polyferric sulfate basically does not contain aluminum ions, which is of great significance in some industrial wastewater treatment. Polyferric sulfate is used as coagulant in papermaking wastewater treatment to dehydrate papermaking sludge, and polyferric sulfate is used as coagulant and complexing breaker in electroplating wastewater treatment. The contact in electroplating wastewater is difficult to treat, but polyferric sulfate can react. Polymeric ferric sulfate has strong decolorization and COD removal effects on printing and dyeing wastewater treatment.


The use of polyferric sulfate in industrial wastewater treatment is small, and the cheap price can well control the cost of wastewater treatment.
