Abstract

The aim of this study is to review and evaluate the idea of treating phenol from wastewater by using titanium dioxide (TiO2) in a photocatalytic reactor to reach an optimal operating treatment condition. A brief review on photocatalytic lab-scale design plus the advantages of using TiO2 and its ability to remove phenol due to its unique chemical properties were studied. Previous photocatalytic experiments were discussed to obtain the ideal operating conditions for wastewater treatment. The best removal efficiency of phenol was found to be at pH 7 under UV irradiation lamps. Although catalyst dosage and initial feed concentrations are mostly preferred at higher values, the perfect dose was 0.2 wt% of TiO2. It was proven that the use of an aeration system would increase the efficiency by 50%.
