Theme: Self-sustaining integrated MFC-LVB-(R) and MFC-LVB(M) system for wastewater treatment and energy recovery: From theory to practical application
Microbial Fuel Cell (MFC) technology has emerged as a low-cost, space-saving, and sustainable technology capable of treating wastewater and generating bioelectricity. MFC reactor employs Anode Respiring Bacteria (ARB) to oxidize organic (COD) and inorganic (NH4+) pollutants anaerobically and transfer electrons to a solid-state anode through extracellular electron transfer (anodic respiration). The MFC technology applied for COD removal and harnessing bioelectricity could be associated with a Microbial Electrochemical Cell (MEC), which is an aeration-free technology for simultaneous anodic nitrification (anodic NH4+ oxidation) and denitrification. MFC can successfully remove COD (> 80%) and SS (> 90%) from domestic wastewater with a low sludge accumulation (sludge yield: 0.10 gVSS/g-sCOD removed) (Koffi and Okabe, 2020a). Furthermore, MFC equipped with a Low Voltage Booster system (LVB-M/R) (Koffi and Okabe, 2020a, 2020b) can harvest usable bioelectricity. Also, MFC electrically powers MEC for simultaneous bioelectrochemical anodic nitrification and cathodic denitrification (cost-effective nitrogen removal) (Koffi and Okabe, 2021).
The lab-scale Integrating MFC-LVB(M/R) technology is an innovative and sustainable approach to address domestic wastewater treatment issues, with less sludge accumulation as a bonus and usable bioelectricity generation. This proposed integrated MFC-LVB(M/R) for low-cost domestic wastewater treatment (COD and NH4+) and usable electrical energy recovery could address scalability and energy- self-sufficiency challenges.
