“…coking wastewater) if the MFC is applied alone due to low Coulombic efficiency. 61,65 The complexity of some actual wastewaters led to alternative metabolisms such as methanogenesis and consequently dramatically reduced the Coulombic efficiency. Additionally, MFCs still faced challenges in the biodegradability of some recalcitrant substances in industrial wastewaters.…”

“…Thus, MFCs coupled with other processes such as an anaerobic-aerobic sequential reactor and a MFC coupled system, and MFC coupled with electro-oxidation process can further improve efficiency of recalcitrant wastes treatment. 65,66 Apart from the sole substrates of recalcitrant substances in bioanodic MFCs, co-metabolism using multiple and co-present substrates is one alternative for recalcitrant wastes treatment.…”

Recalcitrant wastes including dyes, pesticides, explosives, heavy metals, polyalcohols, furan derivatives and phenolic substances, are of special concern owing to their recalcitrance and persistence in the environment. Bioelectrochemical systems (BESs) including microbial fuel cells (MFCs) and microbial electrolysis cells (MECs), integrate three important wastewater treatment options, namely, biological treatment, electrolytic dissociation and electrochemical oxidation/reduction, and are regarded as a new sustainable and effective strategy for treatment of these wastes. The simultaneous and cooperative roles of these multiple units running in parallel in BESs contribute to the efficiency of recalcitrant waste treatment, while substrate metabolism is considered to be a key step triggering different unit operations. An up-to-date review is provided on recent research and development in BESs-based recalcitrant wastes treatment. MFCs and MECs, as two types of BESs, are summarized in terms of treatment efficiency, recalcitrant substance metabolic pathway and microorganism diversity after a brief introduction to the electrochemical process for recalcitrant waste treatment. The scientific and technical challenges that have yet to be faced in the future are also discussed.

“…The wastewater from coal coking was studied in an Microbial Fuel Cell‐ Electro Oxidation (MFC‐EO) system for organic matter removal efficiency and bioelectricity. Such wastewater contains aromatic nitro compounds, phenols, thiocyanates, and ammonia . The study used carbon‐cloth electrodes with air contact on the cathode side; the study claims the role of aromatics in the wastewater to have positive impact on power production, with COD removal efficiency of around 82% and nitrogen removal of 68%, with no significant voltage and current generation.…”

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

“…[2][3][4][5][45][46] While MFCs integrated with conventional electro-oxidation and membrane bioreactors have been developed, [4,52] the self-driven MFC-MEC system is being representatively proceeded for either hydrogen production or complete recovery of cobalt from solid wastes of LiCoO2. [15][16]18,53] Compared with previous self-driven MFC-MEC system for Cr(VI), Cu(II) and Cd(II) recovery, [19] It should be pointed out that mixed metal concentrations higher than either 5 mg L -1 Cr(VI), 1 mg L -1 Cu(II) and 5 mg L -1 Cd(II), or 1 mg L -1 Cr(VI), 5 mg L -1 Cu(II) and 5 mg L -1 Cd(II) would be incompletely removed and these metal species cannot be thoroughly separated from each other using the present self-driven MFC-MEC system.…”

A self-driven microbial fuel cell (MFC) - microbial electrolysis cell (MEC) system, where electricity generated from MFCs is in situ utilized for powering MECs, has been previously reported for recovering Cr(VI), Cu(II) and Cd(II) with individual metals fed in different units of the system in batch operation. Here it was advanced with treating synthetic mixed metals' solution at appropriately adjusting composites in fed-batch and continuous flow operations for complete separation of Cr(VI), Cu(II) and Cd(II) from each other. Under an optimal condition of hydraulic residence time of 4 h, matching of two serially connected MFCs with one MEC, and fed with a composite of either 5 mg L Cr(VI), 1 mg L Cu(II) and 5 mg L Cd(II), or 1 mg L Cr(VI), 5 mg L Cu(II) and 5 mg L Cd(II), the self-driven MFC-MEC system can completely and sequentially recover Cu(II), Cr(VI) and Cd(II) from mixed metals. This study provides a true sustainable and zero-energy-consumed approach of using bioelectrochemical systems for completely recovering and separating Cr(VI), Cu(II) and Cd(II) from each other or from wastes or contaminated sites.
