Studies on treatment of bitumen effluents by means of Advanced Oxidation Processes (AOPs) in basic pH conditions

The paper presents the results of studies on chemical treatment of effluents from production of bitumen of petroleum origin. Due to the presence of sulfide ions, the pH of these effluents is strongly alkaline. Several Advanced Oxidation Processes (AOPs) were studied, including the use of hydroxyl and sulfate radicals oxidants, the hydrodynamic cavitation as well as sonocavitation. The best processes allow to obtain 45% reduction of chemical oxygen demand value (COD) along with effective degradation of the majority of the volatile organic compounds present in the effluents. Some of the studied processes, especially the one using sonocavitation revealed to produce high amounts of VOCs by-products.
