Abstract


  • The long-term performance of a bioaugmented membrane bioreactor (MBR) containing

    a GAC-packed anaerobic zone for treatment of textile wastewater containing structurally

    different azo dyes was observed. A unique feeding strategy, consistent with the mode of

    evolution of separate waste streams in textile plants, was adopted to make the best use of the

    GAC-zone for dye removal. Dye was introduced through the GAC-zone while the rest of the

    colorless media was simultaneously fed through the aerobic zone. Preliminary experiments

    confirmed the importance of coupling the GAC-amended anaerobic zone to the aerobic MBR

    and also evidenced the efficacy of the adopted feeding strategy. Following this, the robustness

    of the process under gradually increasing dye-loading was tested. The respective

    average dye concentrations (mg/L) in the sample from GAC-zone and the membranepermeate

    under dye-loadings of 0.1 and 1 g/L.d were as follows: GAC-zone (3, 105), permeate

    (0, 5). TOC concentration in membrane-permeate for the aforementioned loadings were

    3 and 54 mg/L, respectively. Stable decoloration along with significant TOC removal during

    a period of over 7 months under extremely high dye-loadings demonstrated the superiority

    of the proposed hybrid process.
