Abstract
The final goal of this research is to realize the efficient utilization of radicals such as atomic oxygen, OH radical, and ozone for water purificatio n. The radicals were generated by a discharge occurring inside the bubbles produced by a bubbling tube immersed in water. The Blumlein line, a repetit ive pulsed power generator, was used as the power source. In the experiment s, a maximum ozone concentration of approximately 300 ppm was obtained when the repetition rate of pulsed power generator, the peak value of applied v oltage and the gap length were 15 pps, approximately 30kV, and 7.5 mm, resp ectively. Oxygen was used as the bubbling gas. The time duration of voltage pulse was approximately 200 ns.
