Characteristics and Application

Polyferric Silicate Sulfate (PFSS) is polymerized based on double salts products of PFS series, with wide range of pH value, its floc settling turbidity is better than PFS. PFSS is widely used in steel wastewater, dye wastewater, coal washing wastewater, metallurgy wastewater, papermaking wastewater and other industry wastewater with good decolorization and large colloidal flocculation, and higher removal rate of CODcr in papermaking wastewater treatment. PFSS is a new kind of inorganic polymer flocculant.
