Abstract

The inoculum biomass was collected from a pilot-scale (3 m³ process tank) nitritation-anaerobic ammonium oxidation (ANAMMOX) (deammonification moving bed biofilm (DeaMBBR)) reactor demonstrating the highest total nitrogen removal rate (TNRR) of 0.33 kg N m⁻³ day⁻¹. This biomass was used for inoculating the anodic chamber of a microbial fuel cell (MFC) to investigate the capacity of DeaMBBR biomass to act as an exo-electrogenic consortia. Performance of MFCs inoculated with ANAMMOX-specific consortia collected from DeaMBBR (MFC-ANA) and another MFC-CON inoculated with a septic tank mixed anaerobic consortium as a control was investigated for electrochemical performance and wastewater treatment efficiency. These MFCs were operated for the total duration of 419 days during which regular feed was given and performance was monitored for first 30 cycles and last 30 cycles, with each cycle of 3 day duration. The MFC-ANA continuously generated bio-energy with higher volumetric power density (9.5 W m⁻³ and 6.0 W m⁻³) in comparison to MFC-CON (4.9 and 2.9 W m⁻³) during the first 30 and last 30 cycles of operational period, respectively. MFC-ANA also achieved 84 ± 2% and 80 ± 2% of COD removal efficiency and 89 ± 4% and 73 ± 2% of total nitrogen removal efficiency during first 30 and last 30 cycles of operational period, respectively. The improvement of nitrogen removal and power production in case of MFC-ANA over MFC-CON could be attributed to the ANAMMOX-denitrifiers populations and Trichococcus (14.92%) as denitrifying exo-electrogenic microbes (4.46%), respectively.
