The purpose of this study is to clarify the coagulation performance of natural coagulant and to develop effective coagulation method for turbid water in a reservoir. Through the experiment, we have obtained three findings. The first is that both distribution of coagulant and circulation of turbid water are indispensable for any sizes’ experiment. The second is that pH of allopane solution water should be arranged to be acid if distribution procedure is omitted. The third is that the allopane has a limitation of coagulation performance and the capacity of coagulation can be measured by the observation of zeta potential. |
