AB  - 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/m<sup>2</sup>, electrode surface area of 1.3 m<sup>2</sup>, conductivity of 2200 &#956;S/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/m<sup>3</sup>, respectively.
