Ozone disinfection: ozone is a broad-spectrum fungicide, which can kill bacterial propagules and spores, viruses, fungi, etc., and destroy botulinum toxin. The ozone sterilization mechanism achieves the sterilization effect by destroying the structure of the microbial membrane by oxidation. Ozone first acts on the cell membrane, causing damage to the membrane components and causing metabolic disorders. Ozone continues to penetrate the membrane and destroy lipoproteins and lipopolysaccharides in the membrane, changing the permeability of cells, resulting in cell lysis and death. Ozone inactivates viruses by destroying viral ribonucleic acid (RNA) or deoxyribonucleic acid (DNA) by oxidation.

Pasteurization: refers to the process of heating a liquid to a certain temperature and continuing for a period of time to kill fermenting microorganisms that can cause disease, spoilage, or unwanted needs. Pasteurization has two main functions: (1) periodic disinfection of pretreatment units such as activated carbon in purified water systems, periodic disinfection of RO/EDI units, and periodic disinfection of storage and distribution pipe network units; (2) It is used for microbial inhibition during the normal operation of the water for injection system.


Chemical disinfection: Chemical disinfection refers to the use of chemical disinfection drugs to act on microorganisms and pathogens, denatured their proteins, lost normal function and died. At present, chlorine-containing disinfectants, oxidation disinfectants, iodine disinfectants, aldehyde disinfectants, heterocyclic gas disinfectants, phenolic disinfectants, alcohol disinfectants, quaternary amine disinfectants, etc. are commonly used.
