The ozone molecule contains three oxygen atoms whereas the normal oxygen molecule contains only two. Ozone is a very reactive and unstable gas with a short half-life before it reverts back to oxygen. Ozone is the most powerful and rapid acting oxidizer man can produce, and will oxidize all bacteria, mold and yeast spores, organic material and viruses given sufficient exposure.
The advantages of using Ozone include:
1. Ozone is primarily a disinfectant that effectively kills biological contaminants.
2. Ozone also oxidizes and precipitates iron, sulfur, and manganese so they can be filtered out of solution.
3. Ozone will oxidize and break down many organic chemicals including many that cause odor and taste problems.
4. Ozonation produces no taste or odor in the water.
Ozonation is deficient of residual disinfection. Since ozone is made of oxygen and reverts to pure oxygen, it vanishes without trace once it has been used. Thus, chlorine or another disinfectant must be added to prevent microbial growth during storage and distribution.
