With the increase in population, natural resources of water are being polluted. Ozone technology reveals one of the most efficient and effective method of achieving pollution removal in water. Ozone is the most powerful broad spectrum microbiological control or disinfecting agent available for water treatment. It is highly reactive and unstable. Considering chlorine which is the most commonly used water disinfectant chemical, O3 is 15% stronger oxidizer and kills bacteria 3000 times faster. The important advantage of O3 is that it produces no toxic by products and is environmental friendly. Ozone breaks large and long chain molecules in to smaller building blocks which are easily biodegradable and less dangerous. But ozone cannot treat certain complex pesticides, man-made molecules and inert gases effectively. Considering all benefits ozone is a good choice for water treatment. For efficiency ozone is outstanding as it is the most powerful broadspectrum micro-biological control or disinfecting agent available. Thus if ozone cannot be used to treat a water quality problem, it is likely that no other available oxidant will do the job either. Hence, from the highest reaches of atmosphere to the deepest of ocean ozone is a very efficient protector, provider and recycler.

Ozone was first used in water treatment in the late 1800s and ozone is more widely used in Europe and Asia then the United States. 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.
Ozonation Process
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 (corona discharge simulation of the lightning), or by ultraviolet radiation as in UV-type ozone generators (simulation of the ultraviolet rays from the sun). In addition to these commercial methods, ozone may also be made through electrolytic and chemical reactions. In general, an ozonation system includes passing dry, clean air through a high voltage electric discharge, i.e., corona discharge, which creates and ozone concentration of approximately 1% or 10,000 mg/L. In treating small quantities of waste, the UV ozonators are the most common, while large-scale systems use either corona discharge or other bulk ozone-producing methods.
