Description of the Related Art Drinking water is indispensable to human life, but natural water is contaminated with metals, pesticides, germs, microorganisms, etc. due to environmental pollution, and is not suitable as drinking water as it is. . Except for a large-scale water purification facility such as a water supply system, a conventional simple water purification apparatus removes suspended matters and salts and purifies the water to such an extent that it is transparent and salts cannot be tasted before drinking.

であった。Even in waterworks, sterilization cannot be performed by filtration alone, and sterilization is performed by adding chlorine or ozone to purified water after filtration. Chlorine is a poison and is cumbersome to handle, and ozone treatment requires a large-scale device such as an ozone generator, and it was thought that sterilization would not be possible with a simple water purification device.
Therefore, it was impossible to sterilize highly toxic bacteria such as E. coli and Staphylococcus aureus such as O157 with a simple water purifier.
