Textile processing industries are widespread in developing countries. Among the various processes in the textile industry, the dyeing process uses large volumes of water for dyeing, fixing and washing. Textile industry wastewater is characterized by suspended particles, salts, high pH and high chemical oxygen demand (COD) concentrations that discarding of these toxic wastewaters to the environment will cause a major problem. In this study, electrochemical oxidation of Reactive Black 5 (RB5) dye using bipolar trickle tower (BTT) reactor and Raschig ring shaped boron-doped diamond (BDD) electrodes in recirculated batch mode was fulfilled. Experimental parameters like flow rate, sodium sulfate concentration (Na2SO4) as supporting electrolyte, initial pH, current density and initial dye concentration were examined.
