Ozone sterilisation is a process of killing microorganisms using the strong oxidation of ozone. Compared with other sterilization methods, ozone sterilization has the following characteristics and differences:

1. Reaction mechanism:

Ozone sterilization: Ozone molecules are unstable at room temperature and quickly decompose into oxygen atoms and monooxygen. These single oxygenes have extremely high activity and can quickly contact with microorganisms, oxidise and destroy the structure of microorganisms. Ozone can pass through bacterial cell walls and act on proteins and lipopolysides in cells, changing the permeability of cell membranes and causing cell death. At the same time, it can also oxidise and decompose enzymes and nucleic acids in bacteria, destroy DNA and RNA, thus interrupting the metabolism and reproduction of bacteria.

Other fungicides: such as alcohol, chloride, etc. Their sterilization mechanism is usually achieved by destroying the cell membranes or degeneration proteins of microorganisms.

2. Broad spectrum:

Ozone sterilisation: It has a wide range of sterilization and has a killing effect on various bacteria (including drug-resistant bacteria), viruses, fungi and spores.

Other fungicides: may only be effective for specific types of microorganisms, such as some disinfectants may be effective for bacteria, but the killing effect of viruses or spores is limited.

3. Remaining problems:

Ozone sterilisation: Because ozone will quickly decompose into oxygen after oxidization, there is no residual problem, which is an environmentally friendly disinfection method.

Other fungicides: For example, some chemical disinfectants may leave residues on the item and require subsequent cleaning steps.

4. Application scope:

Ozone sterilisation: suitable for disinfection of air, water, surface and inside objects.

Other fungicides: may only be applicable to specific media or surfaces.

5. Concentration and time:

Ozone sterilization: It is necessary to accurately control the concentration and action time of ozone to ensure the disinfection effect.

Other fungicides: Concentration and time also need to be considered, but may also include pH, temperature and other factors.

6. Security:

Ozone sterilisation: It may be harmful to the human body at high concentrations, so it is necessary to strictly control the environment and concentration when using it.

Other fungicides: There may also be safety risks, especially chemical disinfectants, which need to be used carefully.

Generally speaking, ozone sterilization is an efficient and environmentally friendly disinfection method that requires precise control. It is suitable for the killing of a variety of microorganisms, but it needs to pay attention to the conditions of use and safety. Other fungicides may vary in terms of selectivity, residue and safety.
