| Research Abstract |
The excess growth of cyanobacteria in semi-closed water areas causes coagulation inhibition in drinking water production. Goal of this study is to develop the coagulation promoter for preventing coagulation inhibition and to achieve high efficiency drinking water treatment. In this study, we analyzed inhibitory potential of capsule produced by Microcystis against the coagulation with PACl and coagulation promoting effect of chitosan. Major results obtained by this study are as follows.
-Capsule of one Microcystis cell consumes 1.2×10^<-7>(mg/cell) of PACl.
-Coagulation test using PACl and Chitosan was performed in the presence of Microcystis aeruginosa cells and organic matter. As a result, removal rate of turbidity increased by approximately 50% by using Chitosan as a coagulation promoter.
