Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Civil Engineering Summary: This study shows the ability of Electrocoagulation process to treat domestic wastewater under different conditions and the effect of this conditions on the treatment process , the effect of various voltage (3 V, 6 V, 9 V, and 12 V); various pH values (4, 7, and 10), various types of anode electrodes (Iron, copper, and aluminum) and the electrolysis time on performance of Electrocoagulation process used to treat synthetic wastewater containing soluble starch, phosphorus ,and nitrates. Values of COD, nitrates, and total phosphorus were measured for the influent and effluent in all performed experiments. The results showed that the optimum removal of COD, nitrates and total phosphorus occurred when using aluminum electrode at voltage value of 12 V and pH value of 7.0. When Electrocoagulation process was examined to treat domestic wastewater under optimum conditions obtained from previous experiments, the efficiency of COD removal was 91.9%, efficiency of nitrate removal was 54.2%, and efficiency of total phosphorus removal was 100%. Finally, chemical coagulation with different coagulants was examined to compare its performance to Electrocoagulation process. The results showed that the Electrocoagulation process is more effective in the removal of COD , nitrates and total phosphorus than the chemical coagulation at the same retention time
