Pilot-scale Microbial Fuel Cells (MFCs): A meta-analysis study to inform full-scale design principles for optimum wastewater treatment

Hexavalent chromium waste removal via bioelectrochemical systems – a life cycle assessment perspective

“…1. Since most existing MFCs are currently at the laboratory 4,24 or pilot scale 28,29 was assumed to be located near a tannery site and the process starts with the receipt of chromium laden wastewater for the catholyte stream and urban wastewater for the anolyte stream.…”

“…1. Since most existing MFCs are currently at the laboratory 4,24 or pilot scale 28,29 conventional wastewater treatment that incorporates a dual chamber MFC reactor and subsequent auxiliaries was employed. The treatment plant was assumed to be located near a tannery site and the process starts with the receipt of chromium laden wastewater for the catholyte stream and urban wastewater for the anolyte stream.…”

Industrial bioelectrochemistry for waste valorization: State of the art and challenges

“…By searching in the Scopus database 'microbial fuel cell' AND 'scale-up', 92 articles were found whereas 28 articles were found by searching using 'microbial electrolysis cell' AND 'scale-up' as keywords. Bird et al (2022) defined some criteria for identifying when an MFC study can be considered to achieve the pilot-scale level, which can be extrapolated to the different BES technologies. The criteria consider reactor sizes higher than 10 L, the conduction of the reactor both inside and outside of the laboratory, the operation in either batch or continuous mode, operation times longer than one month and the treatment of any waste stream.…”

Valorization of lignin to obtain platform chemicals via bio‐electrochemical systems: batch and fed‐batch mode analysis

“…shortfalls) in microbial electrolysis cells (MECs) are entirely dependent on current because scaling up MECs will inherently require working with significantly larger electrical currents. 28 The supervision of this characteristic has little bearing on the creation of effective, scalable MPPC designs because the primary goal of microbial peroxide-producing cells is H 2 O 2 production for pollutant degradation and valorization purposes rather than current generation. The MPPC produces H 2 O 2 via the 2 e-pathway, which can be aided by enhancing electrode kinetics.…”
