In this work, aqueous solutions of three azo dyes and a waste water sample taking from a local textile plant have been studied. Effect of several factors such as color, pH, presence of NaCl, applied potential, initial dye concentration and solution flow rate on the removal rate has been investigated. Energy consumption values have been calculated for different initial dye concentrations and flow rates, and shown as the function of applied potential. Removal rates of 98%, 86% and 85% have been achieved with energy consumption values of 0.044 k Whg(-1), 0.106 k Whg(-1) and 0.044 k Whg(-1) for Ostazin Rod H3B, Ostazin Black HN and Ostazin Olive HG respectively. Removal rate of 82% with energy consumption value of 2 k Whm(-3) has been observed for textile effluent.
