Product Details
Polyferric sulfate (PFS), also known as poly iron or SPFS, is a new generation of environmentally friendly products. As an inorganic polymeric flocculant, PFS rapidly neutralizes the negative charge on the surface of colloidal particles in water. It also forms flocs by bridging ions or through adsorption. The resulting flocs are dense and settle quickly, demonstrating excellent coagulation performance. Compared to other inorganic flocculants, PFS exhibits higher purification capabilities and is widely used in the treatment of Qin water, various industrial water sources, industrial wastewater, and urban sewage.
