A study using coagulation-flocculation method for the treatment of low temperature and low turbidity water has been carried out. The efficiency of aluminum sulfate and ferric chloride when used alone and in coupled with polysilicic were studied The reduction efficiency of turbidity is the main evaluating parameters. The influence of different factors in flocculation was studied and the optimal compounding condition was obtained finally.Experimental results showed that at normal temperature under the conditions of pH of 6-8,PSAF with Al/Fe molar ratio of 3:land (Al+Fe)/Si molar ratio of 3:1 had the best turdibity rimoval. The residual turbidity decreased to less than 3NTU in this document. The coagulation-flocculation has different performance with low temperature and low turbudity. The experimental results showed that at low temperature the optimal dosage was less than it at normal temperature.
