Abstract

The electrochemical Fenton (EF) oxidation process was applied for the treatment of textile wastewater with low biodegradability. The effects of current and time on COD reduction, color reduction, pH and temperature were investigated using a laboratory scale electro-Fenton set-up. results showed that with respect to current, the COD and color reduction increased until a maximum value then gradually decreased. Statistical analysis showed that only current had significant effects on the COD removal efficiency while for color reduction, current and time significantly affected the performance of the process. the model for COD and color reductions was found to be quadratic model. The generated model equations for COD and color removal were significant however, the model for color reduction had a significant lack of fit. To get insights into the optimum conditions both models were still used for numerical optimization. The optimum operating conditions were found to be 0.68 A and 10 minutes. At these conditions the predicted COD and color reduction were 97.49% and 85.20%, respectively. The corresponding COD measurement of the treated wastewater is in compliance with the DENR standards while the color is only near compliant. The associated process cost was 6,706.35Php/m³ (desirability of 81%). It was very expensive, indicating that the EF process could only be used when there are no other available treatment process with the same reduction efficiencies.
