The aim of this study was to investigate the treatment of diazo dye Reactive Black 5 (RB5)- containing wastewater using granular activated carbon (GAC)-biofilm sequencing batch reactor (SBR) as an integration of aerobic and anaerobic process in a single reactor. The GAC-biofilm SBR system demonstrated higher removal of COD, RB5 and aromatic amines. It was observed that the RB5 removal efficiency improved as the concentration of co-substrate in the influent increased. The alternative aeration introduced into the bioreactor enhanced mineralization of aromatic amines. Degradation of RB5 and co-substrate followed second-order kinetic and the constant (k 2) values for COD and RB5 decreased from 0.002 to 0.001 and 0.004 to 0.001 l/mg h, respectively, as the RB5 concentration increased from 100 to 200 mg/l in the GAC-biofilm SBR system 2013-12-31T07:11:50Z 2013-12-31T07:11:50Z 2012-05 Article Water, Air, and Soil Pollution, vol. 223(4), 2012, pages 1615-1623 0049-6979 http://link.springer.com/article/10.1007%2Fs11270-011-0969-4 http://hdl.handle.net/123456789/30912 en Springer Science+Business Media B.V. |
