In industrial production, ozone is often used to disinfect and purify water. However, due to the strong oxidizing power of ozone, the remaining ozone in the water may be affected by the next process if it is not removed. Therefore, usually ozone-treated water must remove the remaining ozone before entering the main process.254 nm ultraviolet light is very effective in destroying the remaining ozone, which can decompose ozone into oxygen. Although different systems require different scales, in general, a typical ozone elimination system requires about three times as much ultraviolet radiation as a traditional sterilization system.
