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.

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.

Internal Corrosion

In 1995 the new Skullerud water treatment plant was put into operation. The new water treatment includes colour removal and corrosion control with an increase of pH, alkalinity and calcium concentration in addition to the old treatment, which included straining and chlorination only. Comparative measurements of internal corrosion were conducted before and after the installation of the new treatment plant. The effect of the new water treatment on the internal corrosion was approximately a 20% reduction in iron corrosion and a 70% reduction in copper corrosion. The heavy metals content in standing water was reduced by approximately 90%. A separate internal corrosion monitoring programme was conducted, studying the effects of other water qualities on the internal corrosion rate. Corrosion coupons were exposed to the different water qualities for nine months. The results showed that the best protection of iron was achieved with water supersaturated with calcium carbonate. Neither a high content of free carbon dioxide or the use of the corrosion inhibitor sodium silicate significantly reduced the iron corrosion rate compared to the present treated water quality. The copper corrosion rate was mainly related to the pH in the water.
