DISINFECTION AND DECOMPOSITION OF AIR, SURFACE OF PREMISES AND EQUIPMENT WITH OZON
Ozone is one of the strongest oxidizing agents, which already in low concentrations has high bactericidal, virucidal and mycicidal properties.
Ozone quite easily oxidizes amino acids - both free and constituent proteins, actively reacts with nucleic acids. Cellular lipids are particularly sensitive to ozone, and to a large extent, those that contain unsaturated fatty acids. Lipids are the main component of the cytoplasmic membrane - the first barrier to the penetration of ozone into the cell. As the ozone dose increases, irreversible changes in the physical and structural state of the membranes occur in the plasma membrane of yeast and bacterial cells, which are associated with oxidative destruction of lipids and proteins.
The effectiveness of the inactivation of microorganisms depends on the activity of the reagent, its concentration and the time of exposure of the drug. The environment in which the microorganism is located plays a major role in disinfection. It easily dies under the action of bactericides in water and in the air, especially if it is not protected by organic and inorganic substrates. Disinfecting the surface or thickness of a material is a much more difficult task. The quality of the surface (smooth, rough), the porosity of the material and the chemical nature of the material, its ability to react with ozone, have a significant impact on the efficiency of this process.
The bactericidal properties of ozone largely depend on humidity. When the relative humidity is below 45%, ozone does not have a noticeable bactericidal effect. The boundary of the optimum of its activity lies between 60-80% humidity.
In a number of works, the bactericidal and mycicidal effect of ozonization of the air of the refrigerating chamber (T = 0.8-2.0 oC) on the concentration of ozone and the duration of ozonation was obtained. Within concentrations of 5–15 mg / m3, the degree of dying off of microorganisms increased with an increase in the ozonation time to 10 hours, and then reached a plateau. The bactericidal effect was 97%, mycocidal - 95%. At a concentration of 20 mg / m3, the number of bacteria decreased by 97-99%, mold fungi - 95-97%.
The Federal Commission for Medical Immunobiological Preparations, Disinfection and Perfumery and Cosmetic Products of the Ministry of Health of the Russian Federation, ozone at a concentration of 1.5-3.5 mg / m3 with disinfection exposure time of 60 minutes is allowed for use for disinfecting air in medical institutions.
CJSC “MELP” produces air ozonizers of the OGNK series for disinfection of air and surfaces of various premises.
