Description of the Related Art For example, a pool installed indoors or outdoors, a bath in an inn or a public bath, or the like, is a so-called bleach (salmon powder) that is regularly used to maintain its water quality. However, it is necessary to sterilize it by adding an aqueous solution of high-grade coconut powder) or sodium hypochlorite (NaClO). However, in the past, this work was
Employees of pools and baths are doing it by hand, and since the aqueous solution of calcination and sodium hypochlorite is irritating, be careful when putting it in during business hours. There is a problem in that it requires a great deal of effort to perform the processing because it must be done.

ることが１つの社会問題ともなっている。In particular, since chlorinated powder is a solid powder, it takes a long time for it to dissolve and become uniform in concentration after being charged, and there is also a problem that a pool or a bath cannot be used during that time. In addition, in the case of a water tank placed on the rooftop of a building, or in the case of a bathtub for general household use, it is the current situation that it depends only on the sterilizing power of chlorine contained in tap water, especially in the case of a water tank. One of the social problems is that the water quality deteriorates due to the algae growing inside.

In that case, there is almost no need for human intervention, and there is no need for the operator to directly touch the water to be treated. Further, if the operation of the pump and the energization of the electrode set are automated using a timer or the like, the water treatment can be completely automated.

Moreover, the water to be treated that is returned to the water tank after the sterilization treatment has a higher concentration of chlorine-containing compounds such as hypochlorite ion than conventional treatment agents such as aqueous solutions of solid powder such as calcination and sodium hypochlorite. Is low, and problems such as irritation are sufficiently reduced. For this reason, the above-mentioned processing can be performed arbitrarily or periodically even during business hours such as at a pool or a bath, or the number of visitors, weather,
It can be optionally performed according to the water quality of the water to be treated which changes depending on the temperature and the like.
