Study on the Treatment of Algae-Rich Water with PPC Preoxidation-Coagulation/Sedimentation/Ultrafiltration (UF) Process

Abstract:

Potassium permanganate composites (PPC) preoxidation/coagulation/ sedimentation/ultrafiltration process was used to treat algae-rich reservoir water. The results of the process optimization tests showed that the optimal dosage of polyaluminium chloride and PPC are respectively 3mg/L and 0.4mg/L. The effect of PPC preoxidation on the coagulation/sedimentation/ultrafiltration process was studied on the pilot device. The combined process can control the effluent turbidity under 0.1NTU. The dosing of 0.4mg/L PPC can increase the removal rate of UV254¬ and algae by 10% and 28% respectively. The synergetic effect between PPC preoxidation and ultrafiltration can enhance the removal of pollutants such as organic matter and algae and control the membrane fouling by decrease the foulant load on the membrane
