Özet: In this study, the treatment of wastewater containing surfactant used to prevent the sticking of the raw material pulp pressed in the tire production process, with conventional coagulation and microwave oxidation-supported electrocoagulation processes was investigated. The processes were optimized to ensure maximum chemical oxygen demand removal by the Taguchi experimental design method (L8). With Pareto analysis, it was found that the most effective parameter in microwave oxidation-supported electrocoagulation processes is microwave duration while the most effective parameter in the conventional coagulation process was FeCl3.7H2O dose. Analysis of variance found that the models determined for both processes were significant in explaining chemical oxygen demand removal. The appropriate process has been determined as the microwave oxidation-supported electrocoagulation, with the PROMETHEE method considering the optimum experimental conditions, chemical oxygen demand removal, chemical sludge production, operating cost and the preferability criteria of the processes. In microwave oxidation-supported electrocoagulation process, under optimum conditions, chemical oxygen demand removal efficiency, the amount of sludge production and operating costs were found as 66.9 %, 6.27 g / L and 1.195 € / L, respectively. It was determined that the criteria of chemical oxygen demand removal efficiency and sludge amount had a positive effect on the selection of the process.
