Polyferric Sulfate is an inorganic polymer coagulant with superior performance. Its morphological properties are light yellow amorphous powdery solid, easily soluble in water, and its 10% (mass) aqueous solution is a reddish-brown transparent solution with hygroscopicity. Polyferric sulfate is widely used in the purification treatment of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dehydration, etc.

Application of polyferric sulfate
Polymerized ferric sulfate is a new type, high-quality, high-efficiency iron salt inorganic polymer flocculant, mainly used in water with excellent water purification effect, good water quality, no harmful substances such as aluminum, chlorine and heavy metal ions, and no iron ions. Transfer, non-toxic, harmless, safe and reliable, and has remarkable effects in removing turbidity, decolorization, deoiling, dehydration, sterilization, deodorization, algae removal, COD, BOD and heavy metal ions in water, 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.
Features of polyferric sulfate:
1 A new type of high-quality and high-efficiency iron salt inorganic polymer flocculant;
2 Excellent coagulation performance, dense alum flowers, fast settling speed;
3 Excellent water purification effect, good water quality, no harmful substances such as aluminum, chlorine and heavy metal ions, and no water phase transfer of iron ions, non-toxic, harmless, safe and reliable;
4 It has remarkable effects in removing turbidity, decolorization, deoiling, dehydration, sterilization, deodorization, algae removal, COD, BOD and heavy metal ions in water;
5. The wide range of PH value adapting to the water body is 4-11, and the optimal PH value range is 6-9. The PH value and total alkalinity of the raw water after purification have a small change range, and are less corrosive to the treatment equipment;
6. It has a remarkable effect on the purification of micro-pollution, algae-containing, low-temperature and low-turbidity raw water, especially for high-turbidity raw water;
7 The dosage is less, the cost is low, and the treatment cost can be saved by 20%-50%.
