Decolorization of Textile Wastewater Using Modified Facultative Anaerobic Baffled Reactor

The study deals with a wastewater treatment system which is combination of modified facultative anaerobic baffled reactor (MFABR) and an aerobic unit. The efficient decolorization and biological degradation of the wastewater that contains commercially important cationic red 2GL (azo) in the MFABR under facultative anaerobic conditions are the research focuses. The results indicate that over 95.2% decolorization and about 54.6% COD removal efficiency can be obtained in MFABR. High dye concentration (500 mg/L) still results in over 90.6% decolorization efficiency. The main characteristics of the process are highly efficient decolorization in MFABR and greatly reducing COD in aerobic unit.
