Application: It is used as a water treatment agent in purification of daily water, industrial process water, general industrial waste water, domestic sewage and sludge dewatering. It is effective in the removal of turbidity, color, oil, bacteria, algae, phosphates, heavy-metal, and reducing COD and BOD of the water and wastewater.
It is also used as pigment, catalyst, and dye mordant.
Features: Comparing with other flocculants, this product has the following features
- It is a ferric flocculants. Its property is very stable.
- Its active iron content is as high as 24% sometimes.
- It is higher in the positive charge density and more powerful in electric neutralizing ability than those of the poly ferric sulfate and poly-blend products.
- Excellent in emulsion-breaking and coagulation; In the same concentration, its water solution is light colored than that of poly ferric sulfate; The result water will not be yellowed even over dosage is applied. It is recommended to and widely used in the purification of daily water.
