“…The removal of COD, turbidity, phenol, hydrocarbon, and grease from petrochemical wastewater was studied by Dimoglo et al (2004) using the electrocoagulation (EC) and electroflotation (EF) process. Two laboratory scale reactors were used for the EF, EC, and EF processes, as shown schematically in Fig.…”

“…Previous studies have used a traditional vertical parallel plate cells or horizontal cells with mesh or array of horizontal cylindrical anodes (Chen et al 2000;Chen 2004;Fouad et al 2009;Emamjomeh et al 2009;Zuo et al 2008;Gao et al 2005;Mostefa and Tir 2004;Carmona et al 2006;Dimoglo et al 2004), such simple electrodes suffer from low surface area and low active mass of anode per unit volume of the cell.…”

In separation of oil from oil-water emulsion by electrocoagulation in an electrolytic cell with a fixedbed anode which is made of randomly packed aluminum cylinders in a perforated plastic basket, the cathode was a horizontal aluminum plate placed below the bed anode at the cell bottom. The effects of different variables such as current density, bed height, cylinder diameter, NaCl concentration on the rate of oil removal, and electrical energy consumption were studied. Under optimum conditions, the separation efficiency reached 85 % after 5 min and a maximum of 99 % after 35 min. The rate of oil removal and oil separation efficiency increased with increasing the current density and NaCl concentration. Increasing bed height was found to increase the rate of oil removal and separation efficiency. It was also found that there was an optimum (cylinder diameter) at which the rate of oil removal and separation efficiency were higher than those at other diameters. Electrical energy consumption, which ranged from 0.35 to 27.5 kW h/kg of oil removed, was found to increase with increasing the current density, bed height and decreasing NaCl concentration. Energy consumption was found to decrease at optimum cylinder diameter. For 99 % oil removal, Al consumption under the present range of conditions ranged from 0.017 to 0.34 g/ L of emulsion and the amount of sludge ranged from 0.55 to 1.48 g/L depending on the operating conditions. Comparison of the performance of the present cell with traditional cells shows that the present cell is superior to traditional cells such as the vertical parallel plate cell.
