Effect of Ozone on Bacteria
How ozone kills bacteria and viruses, eliminates odor ?
- A healthy bacillus bacterial cell ( Waiting to ruin your day) .
- Zooming in closer, an ozone molecule (blue) comes into contact with the cell wall.
- As ozone molecules make contact with the cell wall, a reaction called an oxidative burst occurs which literally creates a tiny hole in the cell wall. The cell wall is vital to the bacteria because it ensures the organism can maintain it sshape.
- A newly created hole in the cell wall has injured the bacterium.
- The bacterium begins to loose its shape while ozone molecules continue creating holes in the cell wall.
- After thousands of ozone collisions over only a few seconds, the bacterial wall can no longer maintain its shape and the cell dies.
This is how ozone kills the bacteria and viruses, and eliminates the odor.
As a comparisonbased on 99.99% of bacterialconcentrationbeingkilledand time taken, ozone is:
- 25timesthat of HOCl (HypochlorousAcid)
- 2,500timesthat of OCl (Hypochlorite)
- 5,000timesthat of NH2Cl (Chloramine)
Furthermore, ozone is at least ten times stronger than chlorine as a disinfectant. Chlorine reacts with meat forming highly toxic and carcinogenic compounds called THMs or tri-halomethanes – rendering meats lesser quality products. THMs were also implicated as carcinogens related to kidney, bladder, and colon cancers. Chlorine also results in the production of chloroform, carbontetrachloride, and chloromethane besides THMs. On the other hand, ozone does not leave any trace of residual product after its oxidative reaction.
