Outline of Final Research Achievements

The reaction rate constant of ozone decomposition depended on the initial ozone dose. Namely the change of the quality of dissolved organic matter must be evaluated, which was different from the assumption in the previous researches. On the other hand, the overall indicators between the ozone exposure and the hydroxyl radical exposure had some relationship. Although the dissolved ozone concentrations among the different experimental reactors and experimental conditions in continuous operation were different, there was some tendency. So it may be possible to evaluate the oxidation potential of the ozonation based on the tendency.
