Abstract

Alkalizer or coagulation and alkalizer technology were adopted to pretreat seawater in the study. Turbidity removal was investigated with different pH, mixing time,and mixing speed. The A was the best by contrasting alkalizer A, B and C. Turbidity removal was 99.4%. The effect of boron removal in the seawater was also studied. The results showed that the pH value has a great impact on the boron removal. The highest boron removal was 89% by alkalizer A under pH 11.The best reaction condition for turbidity removal : pH value 10.8,stirring rate 200r/min,reaction time 10 minutes and dosage of PAM 0.5 mg/L.
