Abstract

This research aims to study the optimum conditions and treatment efficiency of the textile direct dyeing wastewater by iron electrochemical-coagulation process using iron electrode. The voltage was varied at 4, 8 and 12 volts and the retention time was varied at 30, 60 and 90 minutes. The results showed that the optimum condition for textile direct dye removal was at a voltage of 12 volts and retention time of 90 minutes which showed the highest removal efficiency, with significant differences (p<0.05) compared to others. The highest removal efficiency of COD, turbidity, TSS, TDS and pH were 91.50%, 88.26%, 74.66%, 58.88% and 21.32%, respectively. The textile direct dyeing wastewater qualities in this optimum condition were within the Industrial effluent standards for Industrial Plant and Industrial Estates of Pollution Control Department.
