Abstract

Separation of water bloom particles from liquid phases by different types of floatation with aids of coagulants as well as their inactivation by treatments with ozone and ultraviolet light of C zone (UV-C) were studied. With the aids of poly aluminum chloride (PAC) or ferric chloride, separation rates of water bloom particles by flotation were about 99.75% and 96.70% on the basis of suspended solids (SS) and chlorophyll a (chl. a), respectively. UV-C showed higher inactivation effect over ozone, and UV-C effect was enhanced significantly by mixing and ultrasonic wave treatments on water samples before the UV-C treatment.<br>It is suggested that complete inactivation of bloom particles might be possible with UV-C treatment if water phase were treated beforehand by a flotation system.
