This research statistically investigates the optimization of Burazol Blue ED (BB) dye removal from aqueous solutions in a batch study under anaerobic conditions. The 3(3) factorial designs were used in order to minimize the number of experiments. The effect of operating conditions, such as initial dye (0.05-0.3 g/L), glucose (1-3 g/L) and inoculum (1.2-2.4 g/L) concentrations, on treatment efficiency was assessed implementing a factorial experimental design. The combined effects of these factors were optimized using factorial design of experiments for decolorization and chemical oxygen demand (COD) removal. Of the three parameters tested, dye and inoculum concentrations had a considerable effect on decolorization, while glucose concentration proved to be statistically insignificant. According to the variance test analysis, the three parameters and the effect of interaction of dye and glucose concentration had a significant effect on COD removal. It is also shown that 33 factorial designs can be suitable to predict anaerobic operating expenses. The continuous treatment studies can be planned using data obtained as a result of a batch study.
