Abstract
A new type of inorganic flocculant, poly silicon boron ferric zinc sulfate (PSBFZ), was synthesized from sodium silicate, ferric sulfate, zinc sulfate and sodium tetra borate by co-polymerization. Comparative flocculation behaviors among poly-aluminium chloride (PAC), poly-ferric sulfate (PFS), poly silicate ferric (PSF) and PSBFZ were explored. The influences of pH, temperature, storage time and dosage on flocculation were studied. The results demonstrate that PSBFZ exhibits the best flocculation performance. Under the optimum conditions, the removal rate of turbidity and chromaticity were up to 99.6%, 99.4%, respectively.
