Removal of microcystin by chlorination

On this study, removal method for microcystin, toxic substance released from the blue-green algae, using chloride was investigated. 82 ~ 98% of Microsystin were removed within 1 hr when sample had microsystin only. However, if the sample had algae cell removal efficiency was decreased to 50%, except the concentration of chloride $10Cl-mg/{\ell}$. As a result, intermediate-chlorination which dose chloride after coagulation process is considered the optimum method for the removal of microcystin because most of algae cell could remove during the coagulation process.
