“…The implementation of MFCs in HF wetlands (so-called MFC treatment wetlands) is very recent and most knowledge is from laboratoryscale studies focused mainly on the quantification of the amount of energy that can be harvested (Doherty et al, 2015). However, some studies report that implementation of MFCs in treatment wetlands may provide a higher degree of treatment and might also be suitable for monitoring treatment performance (Fang et al, 2013) or monitoring clogging in HF wetlands (Corbella et al, 2016a).…”

“…Figure 8.6 shows current available strategies for treatment wetlands operated as vertical flow MFC (adapted from Doherty et al, 2015) and Figure 8.6 (bottom), shows treatment wetlands operated under HF MFCs. Studies dealing with these aspects have only recently been published (Yadav et al, 2012;Fang et al, 2013;Liu et al, 2013;Zhao et al, 2013). The most common material for electrodes are graphite-based materials (either in the form of rods, granules or plates).…”

Three-dimensional biofilm electrode reactors (3D-BERs) were constructed to degrade the azo dye Reactive Brilliant Red (RBR) X-3B. The 3D-BERs with different influent concentrations and external voltages were individually studied to investigate their influence on the removal of X-3B. Experimental results showed that 3D-BERs have good X-3B removal efficiency; even when the influent concentration was 800 mg/L, removal efficiency of 73.4% was still achieved. In addition, the X-3B removal efficiency stabilized shortly after the influent concentration increased. In 3D-BERs, the average X-3B removal efficiency increased from 52.8% to 85.4% when the external voltage rose from 0 to 2 V. We further identified the intermediate products via UV-Vis and gas chromatography-mass spectrometry (GC-MS) analyses, and discussed the potential mechanism of degradation. After the conjugate structure of X-3B was destroyed, all of the substances generated mainly consisted of lower-molecular-weight organics.

h i g h l i g h t sA modular biocathode materials design was developed and optimized in BES. Dechlorination was improved using this composite metal and carbon-based material. SSB/GG/CB was optimum for dechlorination, followed by SSB/CB and SSB/GG. EIS analysis showed that the composite materials could improve the charge transfer. This modular design could be scalable with successive modules for BES scale-up. t r a c tThis study developed and optimized a modular biocathode materials design in bioelectrochemical system (BES) using composite metal and carbon-based materials. The 4-chlorophenol (4-CP) dechlorination could be improved with such composite materials. Results showed that stainless steel basket (SSB) filled with graphite granules (GG) and carbon brush (CB) (SSB/GG/CB) was optimum for dechlorination, followed by SSB/CB and SSB/GG, with rate constant k of 0.0418 ± 0.0002, 0.0374 ± 0.0004, and 0.0239 ± 0.0002 h À1 , respectively. Electrochemical impedance spectroscopy (EIS) demonstrated that the composite materials with metal can benefit the electron transfer and decrease the charge transfer resistance to be 80.4 X in BES-SSB/GG/CB, much lower than that in BES-SSB (1674.3 X), BES-GG (387.3 X), and BES-CB (193.8 X). This modular cathode design would be scalable with successive modules for BES scaleup, and may offer useful information to guide the selection and design of BES materials towards dechlorination improvement in wastewater treatment.
