ALGAE REMOVAL METHOD AND THE SYSTEM WHICH USING THE CHLORINE DIOXIDE

摘要

PURPOSE: A method for removing algae using chlorine dioxide and a device thereof are provided to reduce the used amount of the chlorine dioxide as well as extend a life span of a filtering device by reducing the load applied to the filtering device. CONSTITUTION: A method for removing algae using chlorine dioxide includes the following steps of: sucking raw water in which the algae is included from water in a lake, a river etc(S100); forming flock including the algae by inputting a coagulant to the raw water(S200); separating the floc using air bubbles(S300); inputting the chlorine dioxide to treated water(S400); separating the treated water to solid and liquid(S500); inputting second chlorine dioxide(S600); discharging the treated water to base water(S700).
