“…Furthermore, the intense electric fields necessary for electrical discharges are also lethal to several kinds of microorganisms found in water [22] and show a synergistic lethal effect when combined with conventional disinfectants such as O 3 and H 2 O 2 [23]. The electrical discharges in water may also produce ultraviolet (UV) radiation [24] and shock waves [25,26], which help in the destruction of pollutants [27]. For these reasons direct electrical discharges in water are clearly the best next-generation technologies for water treatment-they are environment friendly and may prove far more effective than conventional oxidants and disinfectants.…”

There is a continuing need for the development of effective, cheap and environmentally friendly processes for the disinfection and degradation of organic pollutants from water. Ozonation processes are now replacing conventional chlorination processes because ozone is a stronger oxidizing agent and a more effective disinfectant without any side effects. However, the fact that the cost of ozonation processes is higher than chlorination processes is their main disadvantage. In this paper recent developments targeted to make ozonation processes cheaper by improving the efficiency of ozone generation, for example, by incorporation of catalytic packing in the ozone generator, better dispersion of ozone in water and faster conversion of dissolved ozone to free radicals are described. The synthesis of ozone in electrical discharges is discussed. Furthermore, the generation and plasma chemical reactions of several chemically active species, such as H
