ABSTRACT

Purification of water is important research area because of increasing pollution and depletion in water resources. Water is normally treated by using carbon filter and chlorination for drinking purpose. The waste water can be treated by using different biological, chemical and advanced treatment processes. Disinfection of water can be carried out by ozonation and U.V. irradiation. U.V. irradiation with ozonation can exhibit synergic effect and can treat the water more effectively. Many investigators have studied ozonation- UV irradiation- hydrogen peroxide treatments in combination and separately and compared them. Present review summarizes the research and studies on application of ozonation, UV irradiation and H2O2 treatment.

Key words: Disinfection, UV treatment, oxidizers, cost effectiveness.
