Abstract Effect of dosing ferroferric oxide (Fe 3 O 4) on the anaerobic treatment of azo dye
Reactive Red 2 (RR2) was investigated in two anaerobic sequencing batch reactors
(ASBRs). System performance, dye degradation pathways, and microbial activities and
structure were examined. The addition of Fe 3 O 4 significantly improved treatment
efficiency, with the removal efficiency of RR2 increased by 116%, the maximum methane
(CH 4) yield potential and the peak CH 4 production rate improved by 7.7% and 22.3%, and …
