Abstract

In the recent years, the strong oxidation power of ozone and radicals has been expected to be useful to water treatment. The purpose of the present study is to improve a micro-bubble generator with gas-liquid interface discharge for the application of water treatment. In the experiment, the decolorization test was conducted using indigo carmine solution as a sample in order to clearly the effect of supplied air volume and applied voltage on the oxidative decomposition. The results show that the decolorization of solution by the gas-liquid interface discharge in micro bubble was succeeded in about 1 hour. In addition, the oxidative decomposition processing speed became faster with increasing of supplied oxygen volume and number of discharges.
