“…With clever design, the physical phenomenon of siphoning can be well applied to wastewater treatment technology. In bench-scale and pilot scale constructed wetland-microbial fuel cells, the researchers used the siphon principle to achieve aeration and agitation. , As shown in Table , compared with the results of other related studies, it is feasible to apply the siphon-driven aeration to OsMFC. In addition, the self-aerated OsMFC constructed in this study was relative feasible for wastewater treatment and electricity generation.…”

The osmotic microbial fuel cell (OsMFC) enables wastewater treatment, electricity generation and clean water generation at the same time. The cathode of OsMFC requires oxygen as a terminal electron acceptor for the redox reaction in the reactor to proceed smoothly. However, aeration, as one of the main energy consumptions during operation, can reduce the economic viability of the reactor. This study constructed an OsMFC system with siphon-driven aeration and investigated whether this intermittent aeration mode has negative effects on OsMFC. The COD removal rate of self-aerated OsMFC was 85.74 ± 2.42%, and the average water flux was 1.80 ± 0.10 L•m −2 •h −1 . Although in terms of COD removal rate, maximum output potential and water production, artificially aerated OsMFC had certain advantages. Self-aerated OsMFC had a lower reverse solute flux, less water loss and more durable electrical energy output. The performance of self-aerated OsMFC for proton and electron utilization was acceptable. In addition, the membrane impedance of self-aerated OsMFC was less than 5 Ω/cm 2 , which was half of the membrane resistance of the artificially aerated OsMFC. Most importantly, the laboratory operation of the self-aerated system can save 0.0329 $/L wastewater under the premise that the total amount of electricity produced is similar.

“…The highest COD removal efficiency was 92% in the 2nd FSR, and the organics were: (1) oxidized by EAB in anaerobic zone and assimilated by microbes in anaerobic zone; (2) degraded by MFC and metabolized by microorganisms in anoxic zone; (3) assimilated and mineralized in aerobic zone (Fig. S9) (Cheng et al 2021).…”

The electrode played an essential role in the operation of CW-MFC system due to its synergistic effect, and the development of electrode strategy has promoted the application of CW-MFC since 2012. In this paper, according to the material and the quantity, the electrode types in CW-MFC were distinctly divided into unified model, composited model, modified model, and multi-electrodes model combined with non-conductive or conductive particle. Different electrode strategies were provided to improve the performance of CW-MFC towards electricity generation, removal of pollutants, and control of greenhouse gas emission, and the coordination mechanism was further reviewed. Furthermore, the development process of the electrode strategy was summarized, and the low-cost, sustainable, and innovated electrode materials were emphatically recommended. For the scale-up application, multi-electrode model was systematically reviewed based on the optimizing of the material, shape, spacing distance, and connection type of electrode. This review may provide guidance to maximize the advantages of CW-MFC applications. Graphical Abstract
