To successfully apply sediment microbial fuel cells (SMFCs) in remediating aquacultural sediments and water bodies on a large scale, SMFC systems with different electrode materials (carbon fiber brush, graphite felt, and carbon fiber cloth) and structural forms were constructed, and the advantages and disadvantages of various electrodes were compared in terms of electricity generation, pollutant removal, and application cost. The results revealed that (1) introducing SMFCs accelerated the removal of pollutants from the overlying water, promoted the degradation of organic matter and the fixation of phosphorus in the sediments, and inhibited water eutrophication and algal blooms; (2) SMFC systems with carbon fiber brushes and graphite felt electrodes exhibited better electricity generation, but the smooth surface of the carbon fiber cloth was not conducive to microbial attachment, leading to a relatively low electrode power density; and (3) the low external resistance accelerated electron transfer and increased the pollutant removal rate.

Sediment microbial fuel cells (SMFCs) have served as an alternative technique to suppress phosphorus release from lake sediments to water bodies and thus mitigate eutrophication. However, the phosphorus regulation mechanism remains unclear. The purpose of this research was to understand the electrochemical influence of an SMFC on the phosphorus concentration in interstitial water. In this study, a lab-scale SMFC was applied to acetate-spiked sediments (ace+) and unspiked sediments (sed) with closed-circuit (CC)/open-circuit (OC) columns, and the circuitry was switched to investigate the relationship between electron transfer and phosphorus concentration. The dissolved total phosphorus (DTP) concentration in the sediment interstitial water in CC columns significantly decreased to below 0.1 mg/L, whereas the DTP in OC columns remained high for nine weeks. After switching the circuit, the DTP in OC→CC columns dropped but that in CC→OC columns increased within one week. At the end of the experimental period, the DTP concentrations in CC/sed, CC/ace+, OC/sed, and OC/ace+ columns were 0.10 ± 0.02, 0.03 ± 0.00, 0.82 ± 0.01, and 1.66 ± 0.12 mg/L, respectively. The respective estimated anode capacitances of those columns were 2.05 ± 0.49, 5.15 ± 0.14, 0.72 ± 0.19, and 0.71 ± 0.12 nF. We concluded that the phosphorus may have been electrochemically attracted and retained on the anode in the sediment because the adsorbed DTP contents and the increased anode capacitances were strongly correlated. Thus, SMFCs can be used for suppressing phosphorus release from eutrophic lake sediments.

The phosphorus reduction in water column was attempted by integrating sediment microbial fuel cells (SMFCs) with the submerged macrophyte Vallisneria spiralis. A comparative study was conducted to treat simulated water rich in phosphate with a control and three treatments: SMFC alone (SMFC), submerged macrophytes alone (macophyte), and combined macrophytes and fuel cells (M-SMFC). All treatments promoted phosphorus flux from the water column to sediments. Maximum phosphorus reduction was obtained in proportion to the highest stable phosphorus level in sediments in M-SMFC. For the initial phosphate concentrations of 0.2, 1, 2, and 4 mg/L, average phosphate values in the overlying water during four phases decreased by 33.3% (25.0%, 8.3%), 30.8% (5.1%, 17.9%), 36.5% (27.8%, 15.7%), and 36.2% (0.7%, 22.1%) for M-SMFC (macrophyte, SMFC), compared with the control. With macrophyte treatment, the obvious phosphorus release from sediments was observed during the declining period. However, such phenomenon was significantly inhibited with M-SMFC. The electrogenesis bacteria achieved stronger phosphorus adsorption and assimilation was significantly enriched on the closed-circuit anodes. The higher abundance of Geobacter and Pseudomonas in M-SMFC might in part explain the highest phosphorus reduction in the water column. M-SMFC treatment could be promising to control the phosphorus in eutrophic water bodies.

Sediment microbial fuel cells (SMFCs) have previously been successfully used to reduce phosphate release from the sediments of eutrophic lakes. In this study, we investigate the risk that SMFCs stimulate sediment decomposition with the unwanted side effect being the release of legacy pollutants stored in sediments. Electrode pairs (16 m 2 each) were installed in a eutrophic lake in Denmark and the electricity production was monitored over more than a year at three electrode fields. Equations were derived that allow calculation of the substrate turnover by the SMFCs from the working potential, the open circuit potential, and the external resistance of the SMFCs. The resulting turnover data suggest that the decomposition of the sediment is only slightly expedited by the SMFCs, and that the decomposition process is not significantly stimulated by the type of SMFCs installed in the lake. The measured maximum power density with stainless steel electrodes in the lake sediment was 0.9 mW/m 2 , which was sufficient to reduce P outflux from sediment. At this power density, the decomposition half-life of the lake sediment (top 5 cm) is calculated to be 277 years, which is only about 10% of natural lake sediment decomposition half-lives. Higher power densities are not necessary for P fixation but inadvertently increase the risk that legacy pollutants buried in the sediment are released.

Two wetland plant-sediment microbial fuel cell systems (PSM1 and PSM2) and one wetland sediment microbial fuel cell system (SM) were constructed to investigate their electricity production performance and the simultaneous migration and transformation of arsenic and heavy metals in sediment and overlying water, arsenic and heavy metals uptake by plants. The bioelectricity generation was monitored for 175 days, and sediment samples were collected at three time points (64, 125 and 200 days) for the analysis. The results showed that plants improved the efficiency of the electricity production by the fuel cell system. The average output voltage was: PSM1 (0.32 V) > PSM2 (0.28 V) > SM (0.24 V)(P ≤ 0.05).The electricity production of the electrodes and the introduction of plants affected the mobility and transformation of As, Zn and Cd in the sediment, which contributed to their stability in the sediment and reduced the release of these metals into the overlying water column. The bioelectricity production process affected the bioavailability of arsenic and heavy metals in the sediment and attenuated metal uptake by plants, which indicated the potential for remediation of arsenic and heavy metals pollution in sediment.

Microbial fuel cells (MFCs) are considered as 1 of the main sources of renewable energy. Besides, as a novel kind of these systems, sediment microbial fuel cells (SMFCs) turned many eyes into their effective application in power generation. Applying SMFCs in areas where nutrient-rich precipitates are used to grow microorganisms has been studied for several times over the last few years. One way to produce renewable and nondestructive energy is the usage of energy found in biomass resources which is proved by MFC technology and all types of it such as SMFCs. In this research, conductive metal brushes with high effective surface were evaluated as cathode electrode in the system. Also, we have investigated the effect of different kinds of sediments in power generation of SMFC. At the beginning, 4 different ecosystems (sea and 3 different areas of the river at a distance of 200, 300, and 400 m far from the sea) were evaluated to assess their potential for electricity generation. In comparison to other ecosystems, river sediment generates the highest power density of about 121 μW/cm2. As well, the influence of catholyte conductivity increment was analyzed with economic salt (NaCl). By this, it was concluded that the output power increases while catholyte conductivity increase. To determine the depth of the cathode between the sediment and water surface, the electrode was placed in 3 different distances of about 0.5, 3, and 6 cm. The results demonstrated that the electrode with less distance from the sediment surface could produce more power and current density.

Sediment microbial fuel cells (SMFCs) are being constructed and operated to produce renewable power for remote monitoring. They are highly advantageous than typical MFCs. In this study, 2 kinds of sludge (activated sludge and anaerobic sludge) were used in SMFCs for investigating their performance characteristics such as the power density production and chemical oxygen demand (COD) removal. The performance of the SMFC with anaerobic sludge was found to be better than that of activated sludge. Experimental results revealed that the maximum power density and COD removal were reported in anaerobic sludge SMFC (10.36 mW/m2, 62%) and the activated sludge SMFC produced 3.97 mW/m2, with a COD removal of 58.2%. The dissolved oxygen values for activated and anaerobic sludge were 3.45 and 0.75 ppm respectively. Control SMFC was run without sediment, and its performance was inferior compared to the SCMFCs with sludge. Generally, the anaerobic SMFC had 2.52 times better power density production than the activated SMFC and control. Moreover, the COD removal was 19% higher than the control. Results concluded that the selection of sludge plays an important role in the SMFC performance. The findings of this study will be useful for the practical applications of SMFCs in real wastewater treatment plants and energy production in the future.

In this study, a multi-anode sediment microbial fuel cell (SMFC) was used to investigate the electricity generation capacity of mixed-culture algae biomass. A multi-anode reactor configuration was used, which had tin-coated copper mesh (TCCM) anode and platinum-coated titanium mesh cathode. The SMFC produced a high-power density of 2965 mW/m2, which is the highest power density reported in SMFC studies so far. The microscopic observations and gene profiling analysis confirmed that the biocompatibility of TCCM favors the bacterial adhesion and enrichment of electroactive bacterial groups (Gammaproteobacteria, Deltaproteobacteria, and Alphaproteobacteria). Our findings indicated that algae biomass could be used as an appropriate feedstock in SMFC to significantly improve electricity generation.
