Project Description
Poly ferric sulfate(PFS)
-
Polyferric sulfate has the functions of decolorization, deodorization, demulsification, and sludge dewatering, and can be widely used in the treatment of industrial wastewater such as mining, printing, and dyeing, and papermaking.
- The antimony removal effect of poly ferric sulfate in printing and dyeing industrial wastewater is much better than polyaluminum chloride.
- The phosphorus removal effect of poly ferric sulfate in urban domestic sewage is much better than polyaluminum chloride.
- Most of the polymerized ferric sulfate in China uses the ferrous sulfate by-product of the titanium dioxide factory as the raw material, and the polymerized ferric sulfate product is obtained by oxidation.
