Abstract

An electrolytic water disinfection method and apparatus for disinfecting water, using water containing hypochlorite and silver ions, or hypochlorite, silver ions and copper ions in solution.

This method and apparatus is useful for disinfecting in a quick, safe and unfailing way, water, such as swimming pool water, washing water for food materials, sanitizing water for machines and implements or containers and drinking water in ships, without any conventional drawbacks.

Claims

1. A method of electrolytic water disinfection, wherein hypochlorite and silver ions are dissolved in water.

2. The method of claim 1, wherein hypochlorite, silver ions and copper ions are dissolved in water.

3. An apparatus for electrolytic water disinfection, comprising

a first electrolysis device having at least a pair of electrodes, which generate silver ions by electric conduction;

a second electrolysis device having at least a pair of electrodes, which generate hypochlorite by electric conduction.

4. The apparatus of claim 3, wherein said first electrolysis device comprises at least a pair of electrodes, which generate silver ions and copper ions by electric conduction.

5. The apparatus of claim 3 or 4, wherein said electrodes of said first and second electrolysis devices are housed in parallel in a casing.
