Abstract

This study was conducted to investigate the optimization and reduction of the toxicity level of the textile industry wastewater using electrochemical oxidation. We assessed the effect of current density and pH and found that the maximum removal of COD and colour was at the current density of 0.28A/cm2 and at a pH of 5. The performance of graphite electrode for COD removal was also reached within 120th minute at 2.5M of NaCl concentration. The biodegradability was improved because ratio of BOD5/COD was increased by 94.46% from 0.015 to 0.271 and the toxicity level was successfully reduced from 1.195% to 0.129%. It was observed that the removal of oil and grease can be up to 82.02%. It can be concluded that the graphite electrode is effective for treating textile wastewater.
