Enhanced coagulation in a typical North-China water treatment plant

Raw micro-polluted water was sampled from a water treatment plant in Gaomi, a town in north China. The treatment with diatomite-enhanced coagulation was investigated, including the effect of dose and the dosing point of diatomite on enhanced coagulation. The results showed that the removal efficiencies of turbidity, color, UV254 and CODMn could reach 78.99 %, 76.19 %, 29.63 % and 22.77 %, respectively, when 15 mg/L diatomite was added at 30 minutes before coagulation. It was found that the optimum pH of diatomite-enhanced coagulation was approximately 6~7.

Ph Range

This research focused on the effect of water temperature and pH to coagulation efficiencies in low turbidity water. And the optimum dose of coagulant was determined. Simulated the treatment processing, the organic matters and turbidity removal capacities of polyaluminum chloride (PACl) were measured in parameters of turbidity, CODMn and UV254 with different experimental conditions. The results indicated that the PACl optimum doses were 28mg/L. By increasing water temperatures in the range of 4°C～18°C, the turbidity removal efficiency was gradually enhanced, while the organic loading removal performed few correlations to temperatures. And the effective pH range was 6.0~9.0, that appeared greater influence on turbidity removal than organic loadings.
