Experimental study on flocculation of low temperature and low turbidity water

Based on the features such as low temperature and low turbidity(from November to next April every year) of the Shidunzi Shanshuiworks,coagu-flocculation experiment in distribution well on raw water of Wulabe reservoir and on water mixed with waste water of filter chamber are conducted in this paper.The results indicate that the optimal dosing quantity of PAC adding into the low temperature and low turbidity water is 12 mg/L with PAM for coagulant and has a better turbidity removal effect,adding time of PAM has a significant influence on the flocculation properties.
