Abstract
The efficiency of electrocoagulation process was evaluated for treatment of petroleum refinery wastewater and quantified as the total oil removed. Various operating variables were examined for their effects on removal efficiency; namely: reaction time, applied voltage, agitation speed, distance between electrodes, electrode materials and their arrangements. The experiments revealed that increases in applied voltage and agitation speed enhance oil removal. The maximum removal efficiency was achieved using (Fe-Al) electrodes. In order to evaluate process, energy and anode consumption were calculated. At best condition, energy consumption was 1.138 kWh/kg-oil where electrode consumption was 0.301 kg/kg-oil. By applying electromagnetic field, the max oil removal was reached after 20 min. The thesis consists of five chapters, chapter one is the introduction. Chapter two is the theoretical background and review of the previous work. Chapter three is the experimental setup, chapter four is the results and discussion and chapter five contains the conclusions and recommendations.
