BACKGROUND Greywater and blackwater treatment is necessary to make sanitation and water reuse possible, and microbial fuel cells (MFCs) have emerged as a promising technology for achieving this objective. Ion exchange membranes play a key role in double chamber microbial fuel cell performance, but there are differences of opinion as to which membrane type is better. RESULTS This project was set up to study the effect of three ion exchange membranes (Nafion® 117, Ultrex™ CMI‐7000 and Ultrex™ AMI‐7001) in MFCs using greywater as catholyte in stacks of three microbial fuel cells each. The results demonstrate that the stacks with cationic membranes (Nafion® 117 and Ultrex™ CMI‐7000) generated higher power (201.50 ± 21.62 and 178.74 ± 56.89 mW m−3, respectively) than those with the anionic membrane stack Ultrex™ AMI‐7001 (71.57 ± 3.46 mW m−3). For the greywater catholyte, a 31% of chemical oxygen demand removal was achieved and proved to be an option as a catholyte in microbial fuel cells for countries that carry out wastewater separation. CONCLUSIONS The results obtained in this study demonstrated that an anion exchange membrane is not a better option for double chamber MFCs. © 2019 Society of Chemical Industry

“…White patches were observed to be formed on the surface of the cathodes of MFC-3 and MFC-4 after 7th or 8th cycle, indicating inorganic fouling in the membrane (picture shown in graphical abstract). This fouling can cause physical blockage to cation transfer, which can in turn cause decrease in power production [20]. Fouling is the formation of an impenetrable film on reactive surface due to accumulation of bacteria, biofoulants and cations, resulting in increased internal resistance of the MFCs (Table 2).…”

“…The use of NDCP with ASA (MFC-2) was able to maintain similar charge transfer resistance (1.86 X) as compared to MFC-4 (1.57 X). Charge transfer resistance is inversely proportional to reaction rate [20], thus a higher R ct value indicates a lower cathodic ORR. This clearly indicates good catalytic behaviour of NDCP when used as cathode material and it is also responsible for better ORR rates for the reason mentioned above.…”

Long term stable performance of a microbial fuel cell (MFC) is difficult to achieve because of scale formation on cathode. Nitrogen doped carbon powder (NDCP) was used as cathode along with amino-trimethylene-phosphate (ATMP) as an anti-scaling agent in a MFC. Maximum power density of 66 mW/m 2 obtained in the MFC using NDCP as cathode, was 2.2 times higher than that obtained with simple carbon powder. High electroactive surface area and meso-porous structure of the NDCP improved electrochemical performance of the MFC having NDCP cathode. After 40 days of operation, the maximum power density decreased by only 12.5% in the MFC using NDCP and having ATMP in its cathode as compared to a 55.6% decrease in the MFC using only carbon powder in cathode due to fouling. Ultrathin shell structure of NDCP catalyst molecules, as evident from transmission electron microscopy (TEM) images, ensured high catalyst performance providing good electron transfer for enhancing oxygen reduction reaction (ORR). Less deposition of calcite molecules on cathode surface, illustrated via X-ray diffraction (XRD) after 40 days of operation, clearly reveals high anti-fouling property of ATMP as a cathode material. ATMP being a commercial antiscaling agent has inherent chelation properties to stop chemical fouling and thus helped in demonstrating stable long term performance of cathode in the MFCs. NDCP along with ATMP could be used for fabrication of a cost effective fouling resistant cathode for long term use by increasing ORR in MFCs to achieve stable power generation by minimizing scale formation on cathode and effective wastewater treatment simultaneously.

“…They are not the only microorganism able to colonize an electrode, but they outcompete bacteria from other environments like wastewater [25,39,40]. The reason for that is related to the unique physiology of Geobacter to couple its oxidative metabolism with the direct electron transfer to extracellular electron acceptors [41].…”

Abstract:Microbial electrochemical technologies (METs) constitute the core of a number of emerging technologies with a high potential for treating urban wastewater due to a fascinating reaction mechanism-the electron transfer between bacteria and electrodes to transform metabolism into electrical current. In the current work, we focus on the model electroactive microorganism Geobacter sulfurreducens to explore both the design of new start-up procedures and electrochemical operations. Our chemostat-grown plug and play cells, were able to reduce the start-up period by 20-fold while enhancing chemical oxygen demand (COD) removal by more than 6-fold during this period. Moreover, a filter-press based bioreactor was successfully tested for both acetate-supplemented synthetic wastewater and real urban wastewater. This proof-of-concept pre-pilot treatment included a microbial electrolysis cell (MEC) followed in time by a microbial fuel cell (MFC) to finally generate electrical current of ca. 20 A¨m´2 with a power of 10 W¨m´2 while removing 42 g COD day´1¨m´2.The effective removal of acetate suggests a potential use of this modular technology for treating acetogenic wastewater where Geobacter sulfurreducens outcompetes other organisms.
