Uses two different metals as electrodes, water flowing between them as an electrolyte, and performs water treatment by utilizing the potential difference between two different metals. For this reason, when the dissolved component of the electrolyte is small in water, such as pure water, a potential difference is less likely to occur and water treatment is said to be impossible. For this reason, the water treatment capacity of this technique is small and unsuitable for treating large amounts of water. Further, like the above-mentioned technique, since the polarity of the electrode cannot be changed, foreign matter adheres to the negative electrode during use, and the negative electrode must be regularly cleaned.

Is a method in which treated water, which is about the level of general purpose water, is caused to flow in the magnetic field of a permanent magnet, and treatment is performed by the electromotive force induced by the magnetic field. This method also has an advantage of not requiring a power source, but cannot sufficiently follow the temperature change and the flow rate change of the treated water, and the usage conditions are limited. The ultrasonic / magnetic method is a method of physically vibrating by ultrasonic waves to destroy suspended matter in the treated water, and then passing it through a magnetic field for treatment.
This system has a higher water treatment capacity than the magnetic system.
However, the life of the ultrasonic transducer is short and the water quality treatment cost is high.

ことを目的とする。The scale attached to the inside of water supply tanks and water distribution pipes using industrial water or general-purpose water is caused by suspended matter existing in these waters. The use of pure water has been quite successful in preventing the scale from adhering to the suspended matter. However, iron bacteria are generated inside the water supply tanks and water distribution pipes of equipment using these pure water, which causes slime. In order to prevent the generation of iron bacteria and the slime adhesion in these facilities, the conventional electric and magnetic treatment methods cannot be applied because the electric conductivity of pure water is low. Therefore, the present invention aims to provide a method and an apparatus for killing and removing iron bacteria that propagate in a water supply tank and a water pipe using pure water having low electrical conductivity, and preventing slime adhesion due to the bacteria.
