Özet
In this study, Taguchi experimental design method was applied to determine the optimum operating conditions for treatment of textile wastewater by electrocoagulation (EC) with aluminum-iron electrode pairs. The experimental parameters investigated were electrode connection type; initial pH (pH.): 5-8; conductivity (250-500 mu s/cm); and electrolysis time (5-20 min). These parameters were varied at four levels to see their effects on the removal efficiency. The results show that the electrocoagulation using Fe-Al electrode pairs with different connection modes were able to treat the dye wastewater. The maximum color removal percentage (99.8%) was achieved by the Fe-Al-Fe-Al electrode connection type, pH 6, current density of 75 mA/cm(2), conductivity of 750 mu s/cm and 15 min electrolysis time for RO 16. On the other hand, optimum conditions were determined as Fe-Al-Fe-Al electrode connection mode, pH 6, current density of 75 mA/cm(2), conductivity of 750 mu s/cm and 20 min electrolysis time for RR 239 and complete decolorization were obtained at these parametric conditions.
