The color removal of textile wastewater was studied using the indirect electrochemical oxidation technique with multi carbon electrodes in a parallel construction. The main objective of the study was to investigate the effects of the various operating parameters, such as initial pH, the amount and distance between electrodes, table salt concentration and cell voltage on color removal of artificial textile wastewater. The experimental result showed that 96.05% of color removal was observed for artificial textile wastewater of 150 mg/L in electrochemical cell containing 8 bars of carbon electrode with the inter-electrode distance of 10 cm, 3.5 g/L table salt, initial pH 6 and cell voltage of 12 V within 60 min of operation. The result showed the use of multi electrode in the indirect electrochemical cell is an effective solution to increase the performance of electro-degradation process. This study proves that this method is a promising technology for remediation of organic pollutant from industrial wastewater.
