Paper Title:
Treatment of Low-Temperature and Low-Turbidity Water Using Modified Active Silica Acid
  Abstract

Difficult for low turbidity water treatment, the treated not reached the drinking water quality standards, the beaker coagulation has been set. In this experiment, the removal effects of low-temperature and low-turbidity water were investigated by using polyaluminum chloride (PAC) and modified active silicic acid. The results indicated that individual addition PAC turbidity removal rate was less than 80%. While adding 67 mg /L PAC and stirring 9-13min, then adding 20 ml /L modified active silica acid of 5% sodium silicate solution and 0.1% polyacrylamide solution with volume ratio of 15:1 and standing 5 min, the coagulant effect was the best and the turbidity removal rate was more than 90%. The optimizing keep time for modified active silica acid was 24 h.
