Abstract
Textile Industries are the most polluting industries as it uses large amount of water and various chemicals for finishing and dying processes. The Electrocoagulation (EC) process is an effective treatment for the textile wastewater with high removal efficiency. Electrocoagulation combines the functions of conventional coagulation, flotation and electrochemistry in wastewater. This study was performed in a bipolar arrangement of four aluminum electrodes connected in parallel. Several Parameters such as dye concentration, applied voltage, conductivity and reaction time were studied to achieve the high removal efficiency. The electro coagulation process showed the maximum dye removal efficiency with an applied voltage of 30V, reaction time of 45 min, conductivity 4560µS/cm and Ph 7 was equal to 97%.Our results indicated a high removal efficiency of COD (90%), BOD5 (85%), TDS (95%).Color removal efficiency was increased in accordance to increase in applied voltage and simultaneously electrode and energy consumption was increased. Electro coagulation technique is found to be highly efficient and relatively fast method as compared to conventional techniques
