The aqueous solution of refractory organic dyes, containing Basic Red, Maxilon Blue, and Basic Yellow, was treated by an electrochemical method using a BDD both as anodes and cathode. The flow through electrochemical cell was adopted and current-controlled electroysis was performed for the system. Operating variables on the process efficiency including current input, pH, reaction time, reaction temperature and flow rate were optimized for the controlled current electrolysis of aqueous dye wastewater. The treatment efficiencies of 20 ppm dye solutions was obtained as high as 98.3 % at the applied current of 100 mA for 1 hr reaction using the flow rate of test solution of 20mL/min. TOC was reduced by 92.2 % at the optimized conditions including the input current of 200 mA for 1 hr reaction for with a BDD electrode.
