“…Regardless of the waste removal, operating at optimum OLR or sludge loading rate (SLR) is critical for an effective performance of MFCs, since both power density and current efficiency depend on the substrate conversion rate directly related to OLR [63,71,[94][95][96][97][98][99][100][101][102][103]. Thus, the energy generation is generally boosted by increasing the OLR up to a maximum, from which higher loading rates decrease the power output of the MFC.…”

A microbial fuel cell (MFC) is a type of bio-electrochemical system with novel features, such as electricity generation, wastewater treatment, and biosensor applications. In recent years, progressive trends in MFC research on its chemical, electrochemical, and microbiological aspects has resulted in its noticeable applications in the field of sensing. This review was consequently aimed to provide an overview of the most interesting new applications of MFCs in sensors, such as providing the required electrical current and power for remote sensors (energy supply device for sensors) and detection of pollutants, biochemical oxygen demand (BOD), and specific DNA strands by MFCs without an external analytical device (self-powered biosensors). Moreover, in this review, procedures of MFC operation as a power supply for pH, temperature, and organic loading rate (OLR) sensors, and also self-powered biosensors of toxicity, pollutants, and BOD have been discussed.

“…This evaluation gives the range of voltages that is achieved with MFCs theoretically. [11][12][13] As shown in Figure 2B, the difference in the voltage readings shows that OCV studies are useful to understand the potential each wastewater contains owing to its organic load content (Table S1), and when an external resistor is used, owing to the direct relation between voltage and resistance from Ohm's law, the value decreases. An important thing to remember here is that effective COD removal is only possible when system generates current, ie, using a resistor to connect the anode and the cathode, 14 further, this reduces the time of operation as well, thereby achieving high COD removal rates.…”

Summary In this study, sewage was simultaneously treated and used to produce electricity using a two‐chambered microbial fuel cell (MFC) with carbon cloth electrodes having platinum coating on the cathode. Porous carbon electrodes are found to be the more suitable for MFCs as the power generation value is high when compared with nonporous surfaces and has a significant impact on the development of stable biofilms on the anode. Wastewater having an initial chemical oxygen demand (COD) of 830 ± 20 mg/L had a removal efficiency from the MFC of around 78%. The initial pH of sewage in the range of 7.69 ± 0.2 saw a shift towards neutral (around 7.4) and biochemical oxygen demand ranging from 300 ± 20 mg/L in the system decreased up to 175 ± 15 mg/L. The cell open circuit voltage peaked at 800 mV. Current and power density was calculated using an external resistance (of 250 Ω) followed by normalizing to the anode surface area. This bioelectricity generation is attributed to the decomposition of the organic matter and is reported to peak at 0.54 mA/m2 and 204 ± 0.38 mW/m2, respectively. Power generation has faster COD removal rates with external resistors compared with open circuit analysis, and MFCs can be effective to support the wastewater treatment infrastructure while at the same time generate electrical power as a value added product.

Microbial fuel‐cell performance depends primarily on five factors: the nature of the electrodes, pH, concentration, temperature, and period of operation. The present work describes work on optimization that has resulted in improved system performance of processes for energy recovery from wastewater by addressing these five parameters. This optimization is related to Monod kinetics, which forms the basis for microbial growth and substrate depletion rate. A difference in energy recovery from wastewater sources has been reported for studies with pure microbial culture and with undefined mixed microbes. Energy utilization research with microbial reactors has grown significantly with varying electrogenic reactor configurations, reductions in material costs, and a global need for power with reduced net CO2 emissions. The potential for future developments of these electrogenic reactor systems is also discussed, including how these systems can be integrated with existing wastewater treatment sources such as anaerobic digesters, and the positive impact they can have on energy security, which is linked with economic stability. Treatment of industrial and domestic wastewater using the microbial reserves can contribute significantly to advancing wastewater treatment infrastructure through effective COD (Chemical Oxygen Demand) removal, and in the process generate value‐added product in the form of bioelectricity. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd
