Three common disinfection methods for ultra-pure water equipment, Xiaobian listened according to the introduction of the technical staff, carefully sorted out a little, for you to introduce in detail
First, ozone disinfection
Xiaobian learned that ozone is a broad-spectrum fungicide that can effectively kill bacteria, viruses, fungi and so on. Its bactericidal mechanism is achieved by oxidizing the structure of the microbial membrane to cause the bacteria to dissolve, die or destroy the RNA and DNA of the virus.
Second, pasteurization
According to the technician, the principle of pasteurization is to use the deficiencies of the virion to heat the liquid to a certain temperature for a certain period of time to kill germs or microorganisms.
Pasteurization has the following two functions in ultrapure water equipment:
1 As a pre-treatment unit for activated carbon such as ultra-pure water equipment, RO/EDI unit and periodic disinfection of storage and distribution pipe network unit.
2 for microbial inhibition during normal operation of the water for injection system.
Third, chemical disinfection (disinfectant water)
Xiao Bian also learned that the disinfection mechanism of chemical disinfection is to act on microorganisms and pathogens to denature proteins and die to achieve disinfection purposes. Common disinfectants currently on the market include chlorine disinfectants, oxidizing disinfectants, iodine disinfectants, aldehyde disinfectants, heterocyclic gas disinfectants, phenolic disinfectants, alcohol disinfectants, quaternary amine disinfectants, etc.
