“…Influent chemical oxygen demand (COD) concentration and hydraulic retention time (HRT) are the pivotal parameters that can overall affect the bioelectricity production and COD removal. Previous studies analyzed the effects of influent concentration and HRT to optimize power generation in MFCs. Similarly, effects of these parameters were investigated, with varied degrees of power performance in CW‐MFCs .…”

Novel earthen pot–plant microbial fuel cells (PMFCs) are constructed as a wastewater filtering and microelectrical power system. Its performance is investigated at different influent chemical oxygen demand (COD) strengths of 50 mg L−1 (P‐COD50), 250 mg L−1 (P‐COD250), and 500 mg L−1 (P‐COD500). Two reference reactors, one unplanted with 250 mg L−1 (UP‐COD250) and another planted with tap water devoid of external supply of organic (P‐COD0), are constructed to show the effects of plants in treatment ability and electricity generation. Maximum average current density is achieved in P‐COD250, that is, 242 ± 10.5 mA m−2 followed by UP‐COD250, P‐COD50, P‐COD500, and P‐COD0. Polarization curves also depicts a similar order for power density. Variations of power output in low and high concentrated units are accompanied with lower substrates for bacteria in the former while the latter is due to osmotic shock of plants at higher COD concentration. At the same influent concentration, planted reactors enhances current density by 12.5%. Organic removal ability is promising in all the reactors, reaching almost 99%. However, plants enhanced, on average, 3% in COD removal. High COD removal is achieved with higher retention time. Planted reactors shows more significant increments in current during daytime after feeding than unplanted reactors, suggesting the role of root exudates via photosynthates in current generation. These results can help in further optimizing of PMFCs in terms of configuration and substrates.

Microbial fuel cell (MFC) is an emerging technology which has been immensely investigated for wastewater treatment along with electricity generation. In the present study, the treatment efficiency of MFC was investigated for hydrocarbon containing wastewater by optimizing various parameters of MFC. Mediator‐less MFC (1·2 l) was constructed, and its performance was compared with mediated MFC with Escherichia coli as a biocatalyst. MFC with electrode having biofilm proved to be better compared with MFC inoculated with suspended cells. Analysis of increasing surface area of electrode by increasing their numbers indicated increase in COD reduction from 55 to 75%. Catholyte volume was optimized to be 750 ml. Sodium benzoate (0·721 g l–1) and actual common effluent treatment plant (CETP) wastewater as anolyte produced 0·8 and 0·6 V voltage and 89 and 50% COD reduction, respectively, when a novel consortium of four bacterial strains were used. Twenty MFC systems with the developed consortium when electrically connected in series‐parallel connection were able to generate 2·3 V and 0·5 mA current. This is the first report demonstrating the application of CETP wastewater in the MFC system, which shows potential of the system towards degradation of complex organic components present in industrial wastewater.

“…The Pd of 16.75W m -3 was the highest in the pH 7 with CE of 45.1%, which is the preferred pH for maximum microbial activity. In the effluent, a significant reduction in COD of 91% and turbidity of 78% were obtained [126].…”

Today, the world is facing climate change challenges with environmental protection being a top priority. Optimizing energy consumption due to its high cost and environment protection is a basic human demand. For industries, reduction in production costs is determinative to success. In this regard, Microbial fuel cell (MFC) is a unique promising technology with wastewater treatment and bioelectricity generation. The MFCs will help reduce energy consumption, curb the wastewater pollution, and standardize it for releasing into the environment. The food industry by producing high volumes of biomass with high organic pollution load are highly prone to use in MFCs as a substrate. Various food industry effluents have been tested, in real or synthetic form in the MFCs. Due to the improvements in the process and progress in novel configurations, better results have been increasingly obtained. Now, the MFC can be used in the industries individually or by integration with other technologies. In this review, the latest results from the use of food industry wastewater in MFCs along with effective process conditions are evaluated.
