Abstract

Azo dyes and their decolorized products are toxic and persistent to biodegradation, but must be properly removed before dye wastewater being discharged to a water body. In this study, a bioelectrochemical system (BES) combined with a membrane biofilm reactor (MBfR) has been investigated for removing azo dye and its reduction products. Acid orange 7 (AO7) as a model azo dye was efficiently removed (96.5
