Three different states of Microcystis aeruginosa, untreated cells, pure cells, and broken cells, were tested for coagulation efficiency to understand their effects on drinking water treatment facilities. Microcystis aeruginosa in its late log-growth phase to early stationary phase, day 12 of culture in the M11 medium, were collected since cells are the most active and reach its maximum population during those periods. Untreated cells samples showed worst results for turbidity removal while turbidities for pure cells and broken cells ones presented the similar levels with those for 0 cell samples after 3 Al-mg/L of coagulant dose. Organic matters from broken cells were not properly removed throughout coagulation processes since samples with organic matters untreated cells and broken cells showed higher levels of E254 and E260 after jar-tests than pure cell samples did. Overall, coagulation processes were highly interrupted when the Microcystis aeruginosa cells and organic matters from cells were co-existed. In addition, algae originated matters which may not remove by coagulation process could lead the secondary pollution when algae are introduced into drinking water treatment facilities during waterbloom. Therefore, the facility should pay attention on the results since they have to assure their water quality for public health.
