“…Gonzalez et al (2017) evaluated sediments from Yucatan where the OM that was found was around 6.74 to 13.13%, removing a maximum of 18% OM, which indicates that BMFC favor sedimentary bioremediation [45]. Zhou et al (2015) removed 9%, which was attributed to the design and configuration of the BMFC [46]. In this study, an increase in the removal of OM in the sediment was observed due to the presence of an anodic material with a large surface area for microorganisms, that is, activated carbon and also due to the fact that the BMFC had aerated cathodes, which favored the oxidation and reduction process [47].…”

Benthic microbial fuel cells (BMFC) are devices that remove organic matter (OM) and generate energy from sediments rich in organic nutrients. They are composed of electrodes with adequate different distances and floating air cathodes in an aqueous medium with saturated oxygen. In this study we proposed to design, build, analyze and evaluate a set of BMFCs with floating air cathodes to test the optimal distance between the electrodes, using sediment from the Bay of Campeche as a substrate. For the analysis of OM removal, COD tests, volatile solids (VS), E 4 /E 6 study and FTIR analysis were performed. Power generation was evaluated through polarization curves, cyclic voltammetry and electrochemical impedance spectroscopy (EIS). We achieved a current density and power density at 10 cm depth of 929.7 ± 9.5 mA/m 2 and 109.6 ± 7.5 mW/m 2 respectively, with 54% removal of OM from the sediment, obtaining formation of aliphatic structures. BMFCs are proposed as adequate systems for bioremediation and power generation. The system at 10 cm depth and 100 cm distance between sediment and the floating air cathode had a good performance and therefore the potential for possible scaling.

“…The prototype of this SMFC is the same as for the aerobic SMFC with the only difference being that there is no external oxygen supply . The entire system is tightly closed, which prevents the introduction of oxygen into the system and maintains an anaerobic environment for the fermentation activities of anaerobic bacteria.…”

Summary Sediment microbial fuel cells (SMFCs) are different from microbial fuel cells because they are completely anoxic and lack a membrane. SMFCs are a novel technology for the simultaneous production of renewable energy and bioremediation of heavy metals. Recently, SMFCs have attracted the attention of many researchers because of their moderate functioning parameters and ability to use a range of biodegradable substrates like glucose, glutamic acid, river water, cysteine, acetate, and starch. The inocula used in SMFCs include river sediment, marine sediment, and wastewater. For power generation, many exoelectrogens in SMFCs have the ability to transfer electrons from electrodes by using natural electron shuttles. Exoelectrogens use four primary pathways to transfer electrons to the electrodes, including short‐range electron transfer through redox‐active proteins, soluble electron shuttling molecules, long‐range electron transport by conductive pili, and direct interspecies electron transfer. The most dominant mechanism is long‐range electron transfer via conductive pili because pili have metal‐like conductivity. The powering by microbes is an emerging technique for the remediation of heavy metals from sediments. The pathways for transferring electrons in electrotrophs operate in the opposite direction from those in exoelectrogens. To further upgrade SMFC technology, this review targets the prototype, operating factors, working mechanisms, applications, and future perspectives of SMFCs. Copyright © 2017 John Wiley & Sons, Ltd.

“…The total removal rate represented the removal rate between the influent and BCF effluent. The levels of COD and NH 3 -N were analysed according to standard methods (Zhou et al, 2015a). NO 3 --N and NO 2 --N levels were determined using ion chromatography (ICS-900, Thermo, USA).…”

Nitrogen from secondary effluents has endangered the aquatic environment and human health. A new experimental setup combining a corncob carbon source and bamboo charcoal filter (BCF) was used to effectively purify artificial sewage treatment plant tail water that had high nitrate and nitrogen content, and a low carbon to nitrogen (C/N) ratio. The nitrogen concentration in the reactor's effluent was below the limit of 15 mg/L when the influent COD concentration was 20 mg/L-60 mg/L, the influent NO 3-N concentration was 15 mg/L-30 mg/L, and the hydraulic retention time (HRT) was 1 h-4 h. The reactor's maximum volumetric load of total nitrogen was 0.585 kg/(m 3 •d). The COD and NO 3-N balances of the reactor indicated that 4.77 g corncob was required to remove 1 g NO 3-N and 2 g corncob was required to release 1g COD.
