Ozone is an allotropic triatomic form of oxygen. An ordinary oxygen molecule consists of two atoms (which is why its formula is described as O2), while an ozone molecule combines three atoms of this element (with the chemical formula O3). This third atom tends to disconnect from the remaining two. This is why ozone is a powerful oxidant and so easily enters into various chemical reactions.

Ozone was already used on an industrial-scale in the 19th century. It currently has a wide range of applications. It is used, among others, for disinfection (mainly of hospital rooms), deodorization, removal of foreign tastes and discolorations, sterilization of drinking water (ozonation), oxidation of rocket fuel. It is one of the most effective known disinfectants and oxidants.


Ozone affects a wide range of microorganisms: bacteria, bacterial spores, viruses, fungi and fungal spores, as well as protozoa. It leads to the oxidation of fatty acids in the cell membrane and then to the oxidation of macromolecules in the microorganisms protein cells, DNA and RNA. These reactions are irreversible and lead to cell death.

Ozone treatment is used to purify drinking water from microorganisms. Mixing water with ozone at a concentration of 0.6-4g/m3 for 10 minutes allows for the destruction of the following microorganisms: viruses, E. coli, Streptococcus, Legionella and other coliform bacteria.

Ozone disinfects various surfaces from viruses, bacteria and fungi. Thanks to the use of a concentration above 300 ppm, it effectively disinfects surfaces from the following microorganisms: Escherichia coli, Staphylococcus auteus, Hemileia vastatrix and Aspergillus niger.

Ozone treatment destroys mycotoxins such as aflatoxin, patulin, cyclopiazonic acid, secalonic acid D, ochratoxin A and zearalenone (ZEN).

Ozone effectively reduces the number of bacteria in the air (it destroys over 90% of bacteria). Viruses are particularly sensitive to ozone treatment. The use of ozone generators is more effective than the use of UV disinfection lamps and HEPA filters. Ozonators are recommended for the disinfection of rooms contaminated with the with SARS virus.
