Abstract: In recent years, people have paid more and more attention to the safety and healthy of drinking water, and promoted the rapid development of reverse osmosis water purifiers. The problem that the total number of effluent colonies of reverse osmosis water purifiers will exceed the standard has always been a “disease” in the water purifier industry. Therefore, the sterilization module has become a new function point of the reverse osmosis water purifier. Based on the analysis of the sterilization technology commonly used in the current water purifier market, this paper describes the principle, device and various factors limiting the application of ozone sterilization technology, and also studies the practical application of ozone sterilization technology in water purifier. The effect is to provide reference for the development of ozone disinfection system equipment for water purifier.

Key words: Reverse osmosis water purifier, Ozone disinfection
