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.

Water treating device

In accordance with the present invention, there is provided a water treatment system for sterilizing water retained in a water container. The system includes a circulation process line for pumping the to-be-sterilized water out of the water container, sterilizing the water through electrolysis, and feeding the sterilized water back into the water container; an arrangement for producing a sterilizing solution having a sterilizing function by electrolyzing an electrolytic solution containing chlorine ions and having a function of promoting an electrochemical reaction; and an arrangement for supplying the produced sterilizing solution into the circulation process line as required. The system can constantly sterilize the water in the circulation process line and, as required, additionally supply the sterilizing solution produced by the sterilizing solution producing arrangement into the circulation process line according to a variation in the quality of the water.

Water treatment system

The present invention is directed to a new water treatment device comprising an electrolytic tank to put water in, an electrode provided in the electrolytic tank, a water treating path for pouring water in a pool and returning to the pool the water in the electrolytic tank, a residual chlorine sensor for measuring the residual chlorine concentration of water, and control means for controlling the energization of the electrode on the basis of the measured value by the residual chlorine sensor, and capable of simply and efficiently sterilizing water stored in pools of various sizes from a swimming pool to a home bathtub.
