Water is essential in our life, every living things needs water in different purposes and quantities. We can get water form it resource for example: Ground Precipitation which includes rain, hail, snow, fog etc. Surface such as rivers, streams, glaciers, Biological sources such as plants , Desalinated seawater , Water supply network and Atmospheric water generator. Water covers about 70% of the Earth's surface. Approximately 97.2% of it is saline, just 2.8% fresh. Potable water is available in almost all populated areas of the Earth. The molecular of water is about two atoms Oxygen and Hydrogen (H2O).

Nowadays, by increasing the pollution which is made by human, water became polluted and includes substances such as human waste, food scraps, oils, soaps and chemicals etc. In this case the percentage of healthy drinking water decreased.

The process of disinfect water by Ozonation by bringing a certain amount of water and mix it with gaseous ozone for a certain period of time. And this will reduce the movement of micro-organisms in water , cause of the contact between ozon and water. The benefits of this disinfection are : effect the range of PH and quickly will react with bacteria and viruses , in addition it has germicidal properties which it is stronger than in chlorine. Furthermore, Ozone can eliminate a wide variety of inorganic, organic and microbiological problems and taste and odor
