In this research the efficiency of electrochemical treatment process with iron electrodes for treatment of a colored wastewater containing Reactive Red 198 in laboratory scale was studied. The effect of operating parameters such as voltage, reaction time, electrolyte concentration, initial dye concentration and interelectrode distance on the dye removal efficiency have been investigated. The experiments were carried out in a plexiglass reactor. The results indicated that electrochemical process is very efficient mothod for dye removal and in the operational condition able to remove color and COD as high as 99% and 66.6% respectively in 30 minutes at 40 volts and 1 cm interelectrode distance. This study revealed that when the voltage and reaction time increased and interelectrode distance decreased, energy consumption, final pH and dye removal, would be increased. Increasing electrolyte concentration, resulted in decreasing retention time for dye removal.
