In this study, anaerobic digestion of textile dye wastewater was carried in a batch reactor using mixed culture obtained from domestic sludge. Response surface methodology (RSM) was employed to study the effect of variables like pH, temperature, textile dye wastewater dilution ratio and MLVSS on dye decolourization and COD reduction. The optimum condition for the maximum decolourization and COD removal efficiency are: pH – 7.5, temperature – 31.40C, wastewater dilution ratio 1:2, and MLVSS – 6750 mg/L. The maximum decolourization and COD reduction was found to be 67.65% and 70.45% at the RSM optimized conditions. From the analysis of variance (ANOVA) results it was found that, the linear effect of wastewater dilution ratio and MLVSS concentration were significant for the decolourization of textile dye wastewater.
