A water treatment apparatus capable of treating a target water to supply treated water containing a controlled effective chlorine concentration

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating a target number (target number) with treated water containing effective chlorine, wherein electrolytic energy for electrolyzing a target water and a target water with treated water is supplied to the closed electrolytic cell. When supply of the object water to the closed electrolytic bath is stopped, the microcomputer 11 generates a stop detection signal. According to the stop detection signal, the electrolytic control circuit 12 changes the electrolytic energy to the changed electrolytic energy. Therefore, the electrolytic cell is operated according to the changed electrolytic energy when the target water is not supplied. The altered electrolytic energy may be intermittent at certain time intervals. In addition, the microcomputer reduces the electrolytic energy that produces the altered electrolytic energy.
