| Abstract | ||||
| Large volumes of oily wastewater are daily produced. Nowadays, environmental wastewater treatment methods attracted more attention. As a result, many treatment methods are concerned with oily wastewater. Electrocoagulation (EC) technology using aluminum as a sacrificial electrode has been widely applied to separate emulsified oil.EC was investigated as an efficient and financial strategy for the treatment of such wastewater by studying the impact of current density and pH on the 500 mg / l oil-in - water emulsion. The used cell reactor consists of a vertical rotating aluminum cylinder electrode as an anode and a fixed cylindrical aluminum tube as a cathode. The impact of few factors on the reactor performance was considered, such as the impact of the speed of tumult, the separate between the terminals and the concentration of salt. In the event that the current density rises and the hole between the anodes diminishes, the lessening of turbidity rises. The increase in the speed of electrode agitation (rpm), decreases the diffusion layer and decreases the elimination of turbidity; decreasing the NaCl content of the aqueous process induces an increase in the degree of turbidity elimination. The ideal conditions of this study about have appeared that the highest separation efficiency (92 percent) was accomplished after 15 min of electrolysis at an introductory pH of 8, current density of 400 A/m2, and initial NaCl concentration of 3 g/l. | ||||
