We have proposed the new water treatment using the active oxygen species such as an atomic oxygen with the oxidation power that is stronger than ozone. Based on the results of simulations we designed the silent discharge type active oxygen generator with a water ejector, which is operated on the discharge conditions of low pressure of 6.6kPa. and high temperature of about 200°C. The experimental results are as follows. (1) The yield of the active oxygen increases with the increase of the discharge tube temperature and the decrease of the gas pressure. (2) The life time of active oxygen is tens msec. (3) The active oxygen oxidizes efficiently the formic acid compared with ozone. It is assumed from these results that the active oxygen species having a strong oxidation power is generated.
