A microbial fuel cell (MFC) is an advance device to contend with three-dimensional problems of fossil fuel-based energy production with high-cost and pollution-generating units. It is an emerging technology of wastewater treatment with energy production. It has the potential to utilize wastewater as feed substrate for microorganisms and to generate bio-electricity. MFCs can also applied in carbon capture, bioremediation, biosensing, bio-hydrogen production and desalination. In this review, the major focus is on treatment of wastewater integrated with bio-electricity production by MFC. Information about various designs of MFC, electrode materials, important process parameters (pH, temperature, etc.) and the most recent integrated technology of MFC with natural water bodies (hybrid MFCs) is also reviewed. This technology holds promise for a clean and green environment, and its successful applications provide a new outlook for engineers and scientists.

Burgeoning industrialization has escalated the energy demand and amplified the insistence on depleting petroleum-based reservoirs. Subsequently, this has imposed a study to pinpoint renewable alternative sources. Employing renewable resources promotes energy production coupled with environmental sustainability. Microbial fuel cells (MFCs) have an encouraging role in producing sustainable and viable electrical energy. It transforms chemical energy into electrical energy with the assistance of microorganisms acting as biocatalysts. It is an emerging technology that has the potential to treat wastewater with bioelectricity production simultaneously. However, scaling up this technology is a major challenge as a plethora of technical constraints limits its application in the real world. This review highlights MFC performance in terms of power generation by utilizing various wastewaters as substrate. Moreover, it sheds light on different MFC designs, mechanisms, and parameters affecting MFC performance along with their pros and cons to generate maximum power output. It concludes possible ways to combat its drawbacks and discusses its future prospects.

Microbial fuel cells (MFCs) are devices that exploit living microbes for electricity generation coupled to organics degradation. MFCs are expected to be applied to energy-saving wastewater treatment (WWT) as alternatives to activated-sludge reactors (ASRs). Although extensive laboratory studies have been performed to develop technologies for WWT-MFCs, limited information is available for comparative evaluation of MFCs and ASRs in terms of organics removal and waste-sludge production. In the present study, laboratory WWT experiments were performed using cassette-electrode MFCs and ASRs that were continuously supplied either with artificial domestic wastewater (ADW) containing starch and peptone or with artificial industrial wastewater (AIW) containing methanol as the major organic matter. We found that these two types of WWT reactors achieved similar organics-removal efficiencies, namely, over 93% based on chemical oxygen demands for the ADW treatment and over 97% for the AIW treatment. Sludge was routinely removed from these reactors and quantified, showing that amounts of waste sludge produced in MFCs were approximately one-third or less compared to those in ASRs. During WWT, MFCs continuously generated electricity with Coulombic efficiencies of 20% or more. In reference to ASRs, MFCs are demonstrated to be attractive WWT facilities in terms of stable organics removal and low waste-sludge production. Along with the unnecessity of electric power for aeration and the generation of power during WWT, the results obtained in the present study suggest that MFCs enable substantial energy saving during WWT.

Anode electrodes are at the focal point of developing microbial electrochemical cells (MECs) for hydrogen production. The extracellular electron transfer (EET) of microorganisms at the interface of anodes and biofilm is the driving force of MECs. This signifies, the role of designing high-performance anodes to maximize the rate of EET and hydrogen production. In this paper, a thorough discussion on the adopted strategies over the past 15 years on anodes to improve biohydrogen production and pollutant removal was presented. Importantly, these strategies categorized as the direct and indirect methods. For the first scenario, the surface of anodes was subjected to various modification methods such as utilizing biochars, nanomaterials, polymers etc. while in the second scenario, the performance of electrodes improved by implementing indirect strategies such as regulating electrodes ratio/spacing, acclimation, electrodes arrangement, magnetic field etc. just to name a few. It was realized that, employing functional materials are at the spotlight of improving anode electrodes while methods such as applying electrical shocks or magnetic field are in early stages. The pros and cons and synergistic impacts on concurrent utilization of methods were also analyzed. Finally, current bottlenecks and future directions for implementing fundamental studies to tackle existing challenges were suggested. • State-of-the-art strategies adopted to improve performance of anode electrodes • Examining the pros and cons of all strategies for various configurations of MEC • Synergies of utilizing combined methods on anode electrodes were elucidated. • Extracting internal/external optimized design parameters boosting biofilm and EET • Presenting the current bottlenecks, challenges and future research directions
