Abstract: This study aims to investigate removal of turbidity from waste water using electrocoagulation method. Two electrocoagulation reactors with a new configuration were used in this study. One of them with aluminum electrodes and the other with iron electrodes. The effects of several parameters such as initial pH, detention time initial turbidity, current density, electrode surface area and conductivity on the removal efficiency were studied. Experimental results revealed that the removal efficiency of turbidity using aluminum and iron electrodes increased with the increase of every parameter stated except for the initial turbidity. It was found that the optimum conditions for aluminum and iron electrodes were: initial turbidity of 100 NTU, current density of 4 A/m2, electrode surface area of 1.3 m2, conductivity of 2200 μS/cm and initial pH of 7 and 9 for aluminum and iron electrodes, respectively. The results showed that within 70 min of detention time and at the optimum conditions, the maximum removal efficiency of turbidity was 98.82 and 97.15% for aluminum and iron electrodes, respectively. At the optimum conditions, it was found that the energy consumption for turbidity removal using aluminum and iron electrodes was 0.621 and 0.362 kW.h/m3, respectively.
