The objective of this study is to investigate the biodegradation of anionic dye orange II and cationic dye methylene blue by anaerobic microbes immobilized on spent granular activated carbon through attachment and under packed column operation. The maximum biodegradation rate of orange II and methylene blue was 0.38 g/h and 0.56 g/h, respectively, with initial dye concentration of 1150 mg/l. Results revealed that the difference in the biodegradation rate of methylene blue and orange II was influenced by the molecular structure of the dye. Adsorption study showed that methylene blue was adsorbed more readily by biofilm than orange II and subsequently contributed to higher removal rate of methylene blue than orange II in GAC-biofilm packed column operation. 2014-03-21T07:46:34Z 2014-03-21T07:46:34Z 2014-01 Article Desalination and Water Treatment, vol.52, 2014 1944-3986 (online) 1944-3994 (print) http://dspace.unimap.edu.my:80/dspace/handle/123456789/32974 http://www.tandfonline.com/doi/full/10.1080/19443994.2014.880155#.Uw0TAM7zjgA 10.1080/19443994.2014.880155 en Taylor & Francis Online |
