Application range:
- Poly ferric sulfate is widely used in the purification of drinking water, industrial water supply, industrial wastewater, printing and dyeing wastewater, and urban sewage. It is widely used in casting, paper making, medicine, tanning, thermoelectricity, coking, mining, etc. It mainly deals with the removal of suspended solids, COD and BOD, decolourization and sterilization, and removal of heavy metal ions and radioactive elements in water.
Usage method:
First, dilute the product into 10%-20% aqueous solution (calculated by the weight of the product). According to different water quality and different uses, first carry out a small test to find the best dosage, to use it in large quantities.
