ABSTRACT:
A water treating device includes a water container for containing water; an electrolyzing chamber for sterilizing water; a water treatment line which couples the electrolyzing chamber with the water container; a sensor for measuring residual chlorine concentration; and a device for controlling the amount of the water to be electrochemically decomposed in the electrolyzing chamber on the basis of the residual chlorine concentration measured by the sensor to keep the residual chlorine concentration of the water to be fed back into the water container within a predetermined range. A bypass line is provided which is branched from the water treatment line upstream of the electrolyzing chamber for sampling the water, introducing the sampled water into the sensor for the measurement of the residual chlorine concentration thereof, and discharging the sampled water into the electrolyzing chamber after the measurement.
