PURPOSE:To provide the system capable of stably producing an ozone-contg. gas by electrolysis even if an electrode is contaminated as the purity of raw water is lowered or the temp. of the electrolyte is increased. CONSTITUTION:This system is composed of a raw water storage tank 1, a device 3 for removing impurities from the raw water and producing high-purity water, an electrolytic cell 8 for producing an ozone-contg. gas and hydrogen gas from the high-purity water, separators 5 and 14 for separating both gases and an electrolyte cooler 16. The purity of the high-purity water is detected, the high-purity water is supplied to the electrolytic cell 8 when its purity is higher than the set value, and the high-purity water is circulated to the device 3 when the purity is lower than the set value. |
