Abstract
The objective of this study is to investigate the possibility of microscreen and ozone for removal red-tide organisms. Ozonated air was bubbled into the reactor through a gas disperser located near the bottom of the column. Filtration equipment was designed by Beaudrey P.C. The results are as follows : (1) the suitable mesh size was 30㎛. (2) the red-tide organisms were removed over 80% within 5min by ozonation and 5㎎ O₃/L·min of injection ozone concentration appeared high removal rate of red-tide organisms per time than 3.5㎎ O₃/L·min, but in removal rate per dosage of ozone, 3.5㎎ O₃/L·min is high than 5㎎ O₃/L·min. (3) The velocity equation of removal red-tide organisms could appeared dC_V/dt=-(2.5×10^(-5))C_V^(2.09)C^(0.93). (4) microscreen and ozone had an effect on red-tide organisms removal.
