When water passes through the diamond electrode, the water molecules are recombined into: O3 (ozone), O (single oxygen), and ·OH (hydroxyl radical), etc. All of these have strong oxidizing properties and can oxidize and decompose the enzymes needed by bacteria and viruses to degrade glucose internally, resulting in the inability of the TCA cycle to proceed. As a result, the ATP required for the life activities of cells cannot be supplied, causing the inactivation and death of bacteria and viruses.
