ACTION AGAINST VIRUSES
Because of its high oxidation potential, ozone oxidizes cell components of the viruses and bacterial cell walls. This is a consequence of cell wall penetration. Once Ozone has entered the cell, it oxidizes all the essential components (enzymes, proteins, DNA, RNA). Once the cellular membrane is damaged during this process, the cell will fall apart and collapse (Lysis).
INACTIVATION OF VIRUSES, BACTERIA, MOLDS, YEASTS AND INSECTS
The antipathogenic effects of ozone have been substantiated for several decades (its killing action upon bacteria, viruses, fungi, and in many species of protozoa).
The effectiveness of disinfection depends on the susceptibility of the target organisms, the contact time, and the concentration of the ozone as indicated in the chart:
| ORGANISM | CONCENTRATION | EXPOSITION TIME |
|---|---|---|
| Virus (Polio virus type-1, Human Rotavirus, Flu, Enteric virus) |
0.2 ppm – 4.1 ppm | < 20 minutes |
| Bacteria (E. Coli, Legionella, Mycobacterium, Fecal Streptococcus) |
0.23 ppm – 2.2 ppm | < 20 minutes |
| Molds (Aspergillus Niger, vari ceppi di Penicillum, Cladosporium) |
2 ppm | 60 minutes |
| Yeasts (Candida Parapsilosis, Candida Tropicalis) |
0.02 ppm – 0.26 ppm | < 1,67 minutes |
| Insects (Acarus Siro, TyrophagusCasei, Tyrophagus Putrescientiae) |
1.5 – 2 ppm | 30 minutes |
