| Outline of Final Research Achievements |
We developed a "recycled water electrolysis system" in which water stored in a tank was repeatedly supplied to a water electrolysis cell and electrolyzed to produce highly concentrated ozone water. Manufacture of the apparatus and ozone water production experiments were carried out in this study. As a result, the concentrations of ozone water reached as high as 159 mg/L in the batch operation and 112 mg/L in the extraction operation at a formation rate of and 0.1 L/min. Also, the system was applied for the generation of concentrated and super-saturated hydrogen water. The supersaturated hydrogen water had dissolved H2 concentration of 1.7 mg/L and was withdrawn from the tank at a flow rate of 0.6 L/min. The dissolved H2 concentration increased to 2.4 mg/L in batch operation.
