Abstract
Deionized water from a deionized water source ( ) for electrolysis is supplied by a pressurizing pump ( ) to an electrolyzer ( ) to obtain a hydrogen gas and ozone gas by means of electrolysis. The pressures of these gasses are maintained at not less than the atmospheric pressure. These gasses at a pressure of the atmospheric pressure or more are dissolved in high-purity water in gas dissolving units ( ) to obtain ozone water and hydrogen water respectively. These ozone water and hydrogen water are introduced into mixer ( ) to adjust pH respectively. In this way, highly-concentrated, gas dissolved cleaning solution is prepared in a short period of time.
