Polymeric ferric sulfate is an inorganic polymer coagulant with excellent performance. The liquid is tan, and the solid is light yellow amorphous powdery solid. Solid products have strong hygroscopicity. Polyferric sulfate is widely used in the purification of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dewatering, etc.
Application Features
New, high-quality, high-efficiency iron salt inorganic polymer flocculant, mainly used for excellent water purification effect, good water quality, no harmful substances such as aluminum, and no water transfer of iron ions, non-toxic, non-toxic Harmful, safe and reliable, it has remarkable effects such as turbidity removal, decolorization, degreasing, dehydration, sterilization, deodorization, algae removal, and removal of COD, BOD and heavy metal ions in water. It is also used for industrial wastewater treatment, such as printing and dyeing wastewater, etc. It is also widely used in foundry, papermaking, medicine, tanning, etc.
Compared with other inorganic flocculants, polyferric sulfate has the following characteristics:
1. New, high-quality, high-efficiency iron salt inorganic polymer flocculant;
2. Excellent coagulation performance, dense alum flowers, and fast settling speed;
3. Excellent water purification effect, good water quality, no harmful substances such as aluminum , and no water phase transfer of iron ions, non-toxic,
Harmless, safe and reliable;
4. The effects of removing turbidity, decolorization, degreasing, dehydration, sterilization, deodorization, algae removal, COD, BOD and heavy metal ions in water are remarkable;
5. The PH value of the water body is suitable for a wide range of 4-11, and the optimum PH value range is 6-9. The pH value and total alkalinity of the raw water after purification have small changes.
Less corrosive to processing equipment;
6. The purification treatment effect of micro-polluted, algae-containing, low-temperature and low-turbidity raw water is remarkable, and the purification effect of high-turbidity raw water is particularly good;
7. The dosage is small, the cost is low, and the processing cost can be saved by 20%-50%.
Industrial Wastewater Treatment
1. The treatment of printing and dyeing wastewater can replace the traditional coagulants of low molecular weight iron salts and aluminum salts. Compared with the traditional coagulants, the amount of coagulants is large, the coagulation efficiency is low, and the residues such as aluminum ions are easy to cause secondary pollution. The dosage is about 150ppm, the dosage is small, the removal rate of COD and chroma is high, and the optimal pH value condition is: 8.0. [2]
2. Electroplating sewage treatment, can be used as coagulant and breaker. The complex is mainly copper-ammonia complex, which is stable in nature, pH=11, and is difficult to directly precipitate with alkali, polyaluminum and other coagulants. It can also be used for reuse of reclaimed water.
3. Papermaking wastewater treatment, instead of polyaluminum chloride, aluminum sulfate, etc., can be used as a coagulant, and can also be used for papermaking sludge dewatering. polymer), only polyaluminum chloride can be used.
