A final purpose of this research is an efficient application of radicals, such as ozone, atomic oxygen and OH radical, for water purification. In our experiments, the radicals with short life-time were generated by a discharge occurred inside the bubbles in water. The bubbles generated by a bubbling tube were passed through a discharge region between the plate electrodes. The diameters of the bubbles generated by the bubbling tube were about 1.5mm and the bubbling gas was oxygen. The magnetic-pulse-compression pulsed-power generator was used as a repetitive power supply. In the experiments, the measurements of ozone concentration were carried out at various flow rates of the bubbling gas and repetition rates. The maximum ozone concentration of about 6.42g/Nm3 was obtained when the repetition rate of pulsed-power generator, the peak value of applied voltage, and the bubbling gas flow rate were 150pps (pulse per second), 22kV, and 0.3l/min, respectively. The discharge energy inside bubbles was obtained by an integration of the power calculated by multiplication of voltage by current. Using the discharge energy inside bubbles, ozone yield of about 64.2g/kWh was estimated.
