Abstract
In the present work, homogenous (photo-Fenton) and heterogeneous photo-assisted systems (Fenton/TiO2/UV, Fenton/ZnO/UV and Fenton/TiO2/UV/Air) were investigated for the treatment of a diesel-oil wastewater emulsion. The augmentation of the photo-Fenton process by heterogeneous TiO2 increased the reaction rate, in terms of COD reduction efficiency from 61% to 71%. Furthermore, the COD removal efficiency was increased to 84% when air was bubbled through the reactants. However, if the Fenton/TiO2/UV/Air process is to be utilized as a treatment for this wastewater, the separation of the TiO2 from the treated effluent would need further consideration.
