抄録

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.
