In the present, experiment reported an emerging approach of integrated treatment processes such as photocatalytic oxidation and biodegradation to increase degradation efficiency of CETP wastewater. Photocatalytic oxidation process performed using hybrid photocatalyst Ti02 impregnated with activated carbon (AC) and biodegradation was performed by developed biofilm on biocarrier. Synthesized TiO2/AC powder was characterized by sophisticated instrumentation. A lab scale photocatalytic bioreactor was designed to remove pollutants from CETP effluent. In this setup, sample was treated with hybrid photocatalyst TiO2/AC under the sunlight and developed biofilm; sampling was done and analyzed. Our results show better degradation within 6 h because of generation of hydroxyl radical and superoxide species reacted with pollutants. This presented experiment shows the rapid degradation and increase removal efficiency of pollutants by using the integrated processes.
