Enhanced low C/N nitrogen removal in an innovative microbial fuel cell (MFC) with electroconductivity aerated membrane (EAM) as biocathode

This study presents an innovative electroconductivity aerated membrane (EAM) coupled with a microbial fuel cell (MFC) to enhance simultaneous nitrification and denitrification (SND) at low C/N ratios. The system achieved maximum power density of 4.20 W/m³ and demonstrated 19.80% improvement in total nitrogen removal under closed-circuit operation compared to open-circuit conditions. The coupled EAM-MFC system successfully integrated wastewater treatment with energy recovery while maintaining coulombic efficiencies of 40.67% (anode) and 42.84% (cathode), operating effectively at a low COD/N ratio of 2.8 g COD/g N.
