Ozone is being used as one of the best water disinfectants worldwide
Ozone is a natural gas, in which 3 atoms of oxygen are combined to form the molecule O3. It is an allotrope of oxygen having much less stability than the diomatic oxygen. Ozone was discovered by Schonbein in France in 1840. It has been named after the Greek word for smell (ozein). O3 is a active, colorless gas which has a distinct smell and is about one and half times heavier than air. Under pressure it becomes unstable and decomposes readily into molecular oxygen. The formation of O3 occurs with the use of energy from oxygen. The formation of Ozone takes place in upper atmosphere by U.V radiation. Commercially ozone is produced by passing the atmospheric air or oxygen into “Corona Discharge” produced by high electric field. Since, 1893 ozone is being used as one of the best water disinfectants worldwide
Ozone is widely used for drinking water treatment because of in excellent disinfection and oxidation qualities. Ozone is a strong, naturally occurring oxidizing and disinfecting agent and can be used safety water treatments. Ozone is 25 times more powerful than hypochlorite acid and 500 times faster. Ozone has greater disinfection effectiveness against microbes like bacteria, virus and cyst compared to chlorination. In addition, the oxidizing properties of ozone can also reduce the concentration of Iron, Manganese and reduce or eliminate the taste and odor problems in water. Thus, the characters of ozone make it the most superior in water disinfectants, comparing to other technologies.
