Title
The coagulation characteristics of Microcystis aeruginosa in different growth phases
이태관Tae Gwan Lee,정연인Youn In Chung
Abstract
The effects of algae and its byproducts on the coagulation of water were investigated on the laboratory scale. Algae which causes of waterbloom has numerous negative effects not only water treatment but also on human health, so we have to remove the algae during water treatment. Therefore we examined the removal characteristics of Microcystis aeruginosa, bloom forming blue-green algae at each growth phase to find their effects on coagulation. Result showed turbidities at lag phase and death phase was lower than turbidities at log growth phase and stationary phase, after coagulation. The probable reason for the difference lies within the cellular activity and inactivity at various phases. This hypothesis will require additional study. Result for measurement of UV_(254), UV_(260) was similar with those of turbidities. The zeta potentials were between -15mV and +15mV after coagulation.
