“…Regarding pH, it can be seen that it increases slightly during the operation time, from 7.0 up to almost 8.5, which is slightly higher than the value obtained using other synthetic fuels, as acetate. 30,31 This value has to be explained in terms of the nature of the compounds contained in the algal biomass. However, no differences were found between the different stacked-MFCs, indicating that number of cells contained in the stack does not have a substantial influence on this parameter.…”

“…Owing to the slow growth and high sensitivity of methanogens to various inhibitory compounds, the organic acids (acetic and propionic acids) produced through fermentation easily accumulate under a high organic load during the anaerobic digestion (Franke‐Whittle, Walter, Ebner, & Insam, 2014). In contrast, in polarized systems, organic matter can be rapidly depleted by exoelectrogens using an anode as an electron acceptor (Asensio, Fernandez‐Marchante, Lobato, Caňizares, & Rodrigo, 2016; Cerrillo, Viñas, & Bonmati, 2016). This is consistent with the higher removals of acetic acid and propionic acid in the polarized system than in the open‐circuit system investigated in this study (Figure 2).…”

In a bioelectrochemical system (BES), microbial community of anode biofilm is crucial to BES performance. In this study, the stratified pattern of community structure and activity of an anode‐respiring biofilm in a BES fueled with brewery wastewater was investigated over time. The anode biofilm exhibited a superior performance in the removal of ethanol to that of an open‐circuit system. The electrical current density reached a high level of 0.55mA/cm2 with a Coulombic efficiency of 71.4%, but decreased to 0.18mA/cm2 in the late stage of operation. A mature biofilm developed a more active outer layer covering a less active inner core, although the activities of the outer and inner layers of biofilm were similar in the early stage. More Geobacter spp., typical exoelectrogens, were enriched in the outer layer than in the inner layer of biofilm in the early stage, while more Geobacter spp. were distributed in the inner layer than in the outer layer in the late stage. The inactive and Geobacter‐occupied inner layer of biofilm might be responsible for the decreased electricity generation from wastewater in the late stage of operation. This study provides better understanding of the effect of anode biofilm structure on BES performance.

“…At the cathode, electrons and protons combine to form water according to the schematic representation showed in Figure 1. Electricity can be produced from a single substrate (e.g., acetate, lactate or glucose), but what is truly innovative is that electricity can also be generated from complex substrates such as domestic sewage and industrial wastewater [2,3]. When these complex substrates are used to feed MFCs, this technology offers the two-fold benefit of energy production and wastewater treatment.…”

Treatment of Mineral Oil Refinery Wastewater in Microbial Fuel Cells Using Ionic Liquid Based Separators

Microbial fuel cells (MFCs) are an environmentally friendly technology that can recover electricity directly from several wastes at ambient temperatures. This work explores the use of mineral oil refinery wastewater as feedstock in single-chamber air-cathode MFC devices. A polymer inclusion membrane based on the ionic liquid methyltrioctylammonium chloride, [MTOA + ][Cl − ], at a concentration of 70% w/w, was used as separator, showing a good efficiency in power production and chemical oxygen demand (COD) removal. The power and the chemical oxygen demand removal reached values of 45 mW/m 3 and over 80%, respectively. The evolution of other parameters of the wastewater including nitrites, phosphates and sulphates were also studied. Kjeldahl nitrogen and sulphates were significantly reduced during MFC operation. The results show that mineral oil refinery wastewater can be used as feedstock in air breathing cathode-microbial fuel cells based on polymer ionic liquid inclusion membranes. This configuration could represent a good alternative for wastewater depuration while producing energy during the process.
