Ozone is a gas composed of three atoms of oxygen (O3). Ozone is the Earth’s Natural Sunscreen and occurs both in the Earth’s upper atmosphere and at ground level.
Ozone is naturally occurring and is created when ultraviolet light from the sun hits an O2 molecule producing monatomic O. The monatomic oxygen temporarily bonds with an O2 molecule to produce O3. In nature the air we breathe contains 10 to 100 parts per billion ozone and this is enough to naturally discourage the growth of many micro-organisms. Overall the atmosphere contains about 600 ppb ozone with concentrations higher in the upper atmosphere where UV light is much more abundant.
Ozone is a form of oxygen. As a strong oxidant, ozone is a type of natural sterilizer, which could effectively oxidize (decompose) organic matter. Unlike the usual chemical disinfectant, it neither causes any negative side effects, nor corrosive. In fact, ozone is an environmental friendly sterilizer that reforms into oxygen molecules after the sterilization process. Ozone in the atmosphere is usually produced via ultraviolet ray released by the Sun and through lightning strikes. This explains why we could always feel like there’s fresh air after thunderstorms, as ozone has been produced during the storm and has cleansed the air in the atmosphere.
Ozone is very useful for industries which requires high level of hygienic and sterilizing standards, such as food safety, commercial laundry, medical, water treatment industries and etc. Ozone is also listed as the approved sterilizer by the US Environmental Protection Agency (EPA), and has been utilized across the globe for more than a century. Many running water treatment in developed countries and most packaged drinking water utilize ozone to sterilize.
