The role of ozone in the treatment of potable water supplies and waste water is as a disinfectant and a powerful oxidant. As a disinfectant, ozone successfully inactivates enteric bacteria, viruses, amoebic cysts, and spores. As an oxidant, ozone oxidizes many inorganic materials completely and rapidly, for example, sulfides to sulphates, nitrites to nitrates, etc. Ozone also oxidizes organic materials such as unsaturated and aromatic compounds, which are oxidized and cleaved at the double bonds; humates and fulvates, which are commonly found in potable water supplies are effectively bleached; and foul-tasting phenol materials are readily destroyed. In addition to the direct reactions of molecular ozone described earlier, ozone can also react indirectly via the radical species formed when ozone decomposes in water. The production of hydroxyl radicals (•OH) can be enhanced by an increase in pH, addition of hydrogen peroxide, or irradiation with ultraviolet (UV) light. Ozone competes with chlorinebased technologies on the water treatment market. The safety of ozone treatment plants is an advantage over chlorine plants. %7 First %@ 9780429183607
