Advanced oxidation process (AOP) with hydroxyl radicals (OH) is considered to be useful for water purification through oxidation; therefore, we proposed a useful passing water-type ozonizer, which could generate discharges even on the liquid surface. We first observed optical emissions due to the discharges and then confirmed the existence of O and OH radicals. Next, decomposition of Methylene Blue was examined. When the discharge was generated between a glass electrode and liquid, the AOP was achieved. The obtained results also indicated that various decomposition and treatment would be possible by selecting discharge form for our passing water-type ozonizer.
