| Abstract | ||||
| Batch electrocoagulation (EC) experiments were carried out to evaluate the removal of COD and O&G from wastewater using two types of electrodes: aluminum, iron, and then mix of aluminum and iron. The effects of operating parameters such as current intensity, initial COD concentration, contact time and NaCl concentration on COD and O&G removal efficiency had been investigated. It was found that increasing current intensity increased COD and O&G removal efficiency. Initial COD concentration had a little effect on removal efficiencies. Results showed that the best performance was obtained using aluminum electrode at a current intensity of 1.3 Ampere and 11.6 volt in 15 min contact time for 1500 mg/L initial COD concentration and 0.5 gm/L NaCl concentration. Under these conditions, COD removal efficiency reached 95.07% and total cost was 0 .84 LE/ /gm COD removal. | ||||
