Polyferric Sulfate PFS

Polyferric sulfate PFS is an inorganic polymer coagulant with superior performance. Morphological property is light yellow amorphous powdery solid, easily soluble in water, its 10% (mass) aqueous solution is reddish brown transparent solution, hygroscopic. Polyferric sulfate is widely used in the purification treatment of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dehydration, etc.

Polyferric sulfate is mainly used for water purification with excellent effect, good water quality, no harmful substances such as aluminum, chlorine and heavy metal ions, and no transfer of iron ions to water. It is non-toxic, harmless, safe and reliable, and can remove turbidity, decolorization, and Oil, dehydration, sterilization, deodorization, algae removal, removal of COD, BOD and heavy metal ions in water have remarkable effects, etc. It is also used for industrial wastewater treatment, such as printing and dyeing wastewater, and is also widely used in foundry, papermaking, medicine, leather, etc.

The difference between polyferric sulfate and polyaluminum chloride
Polyferric sulfate can be divided into liquid, solid and reinforced polyferric sulfate according to the preparation method; polyaluminum chloride can be divided into spray drying type PAC and drum drying type PAC.
The quality between them is very stable, and the differences are as follows according to the effect of use:

1. Both polyferric sulfate and polyaluminum chloride are flocculants in water treatment agents.

2. They are different in color and quality standard. The main quality index of polyferric sulfate is total iron content, while the main quality index of polyaluminum chloride is alumina content.

3. The phosphorus removal and COD and BOD reduction effect of polyferric sulfate is better than that of polyaluminum chloride.

4. Compared with polyaluminum chloride, ferric sulfate has larger alum flowers and faster precipitation.

5. The cost of polyferric sulfate is slightly lower than that of polyaluminum chloride.

The above is the difference between polyferric sulfate and polyaluminum chloride. They have their own advantages and disadvantages, but the application of polyferric sulfate is relatively wider, and we can pay more attention to it when choosing.
