High Chroma Water Treatment by Potassium Permanganate Chemicals in Northeast China
Abstract:
The potassium permanganate chemicals (PPC) was used to enhance the chroma removal of the typical raw water in northeast China. Two dosing points were investigated for PPC application and the optimized dosing point and an optimized dose of 0.5-1.5 mg/L were determined. The results showed that the PPC could solve the problem of chroma residual. The turbidity and CODMn removal were also increased. The PPC was a good alternative of polyacrylamide as coagulation aid and could save some cost.
