Ozone is an unstable gas comprising of three oxygen atoms, the gas will readily degrade back to oxygen, and during this transition a free oxygen atom, or free radical is form. The free oxygen radical is highly reactive and short lived; under normal conditions it will only survive for milliseconds. Ozone is a colorless gas that has an odor similar to smell of the air after a major thunderstorm. Ozone has greater disinfection effectiveness against bacteria and viruses compared to chlorination.  In addition, the oxidizing properties can also reduce the concentration of iron, manganese, sulfur and reduce or eliminate taste and odor problems.  Ozone oxides the iron, manganese, and sulfur in the water to form insoluble metal oxides or elemental sulfur.  These insoluble particles are then removed by post-filtration.  Organic particles and chemicals will be eliminated through either coagulation or chemical oxidation.   Ozone is unstable, and it will degrade over a time frame ranging from a few seconds to 30 minutes. The rate of degradation is a function of water chemistry, pH and water temperature. The formation of oxygen into ozone occurs with the use of energy. This process is carried out by an electric discharge field as in the CD-type ozone generators like corona discharge simulation of the lightning, or by ultraviolet radiation as in UV-type ozone generators like simulation of the ultraviolet rays from the sun. In addition to these commercial methods, ozone may also be made through electrolytic and chemical reactions. The system consists of three major components: ozone generator, in-line mixer, and filter module. The ozone generator plugs into a standard receptacle (115v-60Hz).
