The aim of the present study was to evaluate the treatment performance in the decolorization of Methyl Orange (MO)-containing wastewater and mineralization of intermediate aromatic amines using an integrated anaerobic and aerobic processes by spend granular activated carbon-biofilm under sequencing batch reactor operation (spent GAC-biofilm-SBR). The spent GAC-biofilm-SBR was operated with FILL, REACT, DRAW, and IDLE modes in a time ratio of 2:20:1.5:0.5 for a cycle time of 24 h. The bioreactor was fed with 1 L of MO-containing wastewater daily. The high reductive condition at the bottom layer of spent GAC-biofilm-SBR was responsible for the biological reduction of azo bond and this led to decolorization. Meanwhile, low reductive conditions at the top layer of spent GAC-biofilm-SBR promote the growth of aerobic microbes and caused the mineralization of intermediate aromatic amines. 2014-05-29T04:34:35Z 2014-05-29T04:34:35Z 2013 Article Desalination and Water Treatment, vol. 51(13-15), 2013, pages 2813-2819 1944-3994 http://www.tandfonline.com/doi/abs/10.1080/19443994.2012.750749#.U4azdHKSyyo http://dspace.unimap.edu.my:80/dspace/handle/123456789/34852 en Taylor & Francis
