Abstract : In this study, the treatability of simulated textile effluent including Remazol Brilliant Violet 5R azo dye was investigated in anaerobic–aerobic sequencing moving-bed batch biofilm reactors. Additionally, the competitive biochemical reaction between sulfate and azo dye as electron acceptor in the presence of acetate was also examined. Anaerobic and aerobic reactors had 8 h and 24 h cycle times, respectively. The both reactor performances was determined by monitoring color, sulfate and total dissolved carbon removal efficiencies, color removal rate, aromatic amine formation/removal and pH profile. Sulfate and azo dye bioreductions simultaneously took place in anaerobic condition and the percentage sulfate and color removals by the anaerobic microorganisms were 94.4% and 50%, respectively. The removal of benzene-based and naphthalene-based aromatic amines resulted from anaerobic decolorization process was observed at the aerobic reactor. The results indicated that anaerobic/aerobic sequencing moving-bed biofilm reactors (MBBRs) were effective in terms of color, sulfate, and DOC removal with aromatic amine degradation.
