Ozone generators produce ozone by adding energy to oxygen molecules (O2), which cause the oxygen atoms to part ways and temporarily recombine with other O2 molecules creating ozone (O3). This process occurs in nature by two ways: Lightning (Corona Discharge) or Sun (UV light).
Ozone in Action
Once ozone is produced it reacts with a pollutant, often long-chain carbon (organic) molecules, and breaks it down into less complex (and typically less harmful) molecules through a process called oxidation. Ozone that has not reacted with other molecules will decompose into oxygen over time.
Sources of Oxygen
In light of ozone's properties, it cannot be stored or transported, and must be made on-site. Ozone can be created from:
- Ambient Air - refers to air that is available in the environment, whether it is located indoors or outdoors.
- Dry Air - refers to air that has moisture removed so the dew point is -70° F or lower
- Concentrated Oxygen - refers to an oxygen supply, which is at least 90% pure, with moisture removed to a dew point of -40° F
Industrial ozone generators work very similar to ambient air units except they require very clean and very dry air or oxygen and have a corona cell specially designed to generate very high ozone concentrations.
