| Abstract: | A simplified engineering analysis developed by investigations of the energy levels and the data of ozone decomposition is presented. Experiments have been conducted by generating ozone from the same ozone generator by two ways and keeping the hydrodynamic conditions identical during ozonation. Ozonation conducted in various media such as gas, gas-liquid and gas-solid supports the assumptions of the presence of excited ozone species and variation in reactivity. The variation in reactivity linked with ozone generation shows an increase in the case of sawdust bleaching. The reactivity is the same for the removal of total organic carbon from water, and a higher ozone decomposition without significant reaction with methyl red solutions and coliform inactivation is observed. |
