Enhanced biogas production and biodegradation of phenanthrene in wastewater sludge treated anaerobic digestion reactors fitted with a bioelectrode system

The purpose of this study was to investigate the enhanced biogas production and biodegradation of phenanthrene in sludge treated anaerobic digestion (AD) reactors fitted with a bioelectrode system (AD-MEC reactors). Different cathodes were considered for installation in the AD-MEC reactor. The result showed that the maximum methane yield (113.45 L/kg TS) and the highest phenanthrene degradation rate (52.3%) were obtained in a reactor with a...
