“…The maximum power densities obtained in this study were comparable to the reported values in the literature for treatment of phenanthrene and benzene, as well as benzene‐ and ammonium‐contaminated groundwater in MFCs, that is, ~25–300 mW/m 3 (Adelaja et al, ; Wei et al, ). Groundwater is often contaminated by a variety of organic and inorganic contaminants, for example, 1,4‐dioxane is often found co‐contaminated with chlorinated hydrocarbons (e.g., TCE and TCA; Stefan & Bolton, ; Zhang, Gedalanga, & Mahendra, ).…”

“…Microbial fuel cell (MFC) is a special type of bioelectrochemical system with no supply of external voltage, but instead, generation of renewable energy from the water treatment process. Previously, different types of toxic and recalcitrant organic pollutants, such as benzene, phenol, naphthalene, phenanthrene, and furfural, have been effectively treated through oxidative processes in anode chambers of MFCs, and maximum power densities of 7–220 mW/m 2 have been achieved (Adelaja, Keshavarz, & Kyazze, ; Wang, Luo, Fallgren, Jin, & Ren, ; Zhou et al, ). Besides, MFCs have been utilized to treat groundwater polluted by both organic contaminants, such as benzene and phenolic compounds in anode chambers, as well as inorganic contaminants, such as nitrate, perchlorate, and Cr(VI) in cathode chambers (Butler, Clauwaert, Green, Verstraete, & Nerenberg, ; Hedbavna, Rolfe, Huang, & Thornton, ; Liu, Lai, Ye, & Lin, ; Pous, Puig, Coma, Balaguer, & Colprim, ).…”

A two-chambered microbial fuel cell (MFC) was used for the first time for the remediation of an emerging contaminant-1,4-dioxane in its anode chamber. Groundwater historically detected 1,4-dioxane contamination was sampled from a Superfund site.Comparative study was carried out between metabolic (i.e., 1,4-dioxane as sole carbon source) and cometabolic (i.e., 1,4-dioxane and methanol as carbon sources) anodic degradations. It was found that cometabolic degradation increased 1,4-dioxane removal by 10%-52% after 7 days and increased maximum power production of the MFC by 18% to 88.9 mW/m 3 . Oxalic acid was detected as a main metabolic degradation product. Beside oxalic acid, acetic acid and isopropanol were also detected as main products for cometabolic degradation. The presence of a biofilm for 1,4-dioxane anodic degradation was observed by a scanning electron microscopy. Phyla of Bacteroidetes, Firmicutes, and Proteobacteria, as well as a variety of species, were identified for the first time-especially Rikenella sp. and Solitalea canadensis, whose relative abundances were the highest of 18.8% and 24.0% for metabolic and cometabolic degradation, respectively. This study provided an innovative and sustainable approach for 1,4-dioxane anodic biodegradation, which would be potentially utilized for remediation of groundwater contaminated by 1,4-dioxane. © 2019 Water Environment Federation • Practitioner points• Groundwater contaminated with 1,4-dioxane was remediated in the anode chamber of a two-chambered microbial fuel cell. • Cometabolic pathway increased 1,4-dioxane removal and power production of the MFC compared to metabolic pathway. • The presence of a biofilm for 1,4-dioxane anodic degradation was observed, and oxalic acid was a main degradation product. • This study would be potentially utilized for 1,4-dioxane-contaminated groundwater remediation with simultaneous energy production. • External voltage supply for bioelectrochemical remediation of groundwater would potentially be reduced when treating chlorinated hydrocarbons co-occurred with 1,4-dioxane.

“…Recently, Kirmizakis et al 2019 In situ treatment of phenantrene and benzene contaminated groundwater with a MFC was reported by Adelaja et al (2017), where a tubular MFC was designed with carbon felt anode exposed to the contaminated groundwater and used for long term operation (about 155 days) ( Figure 2F). The system was able to remove up to 90% petroleum hydrocarbons at the anode and up to 79% bromate (BrO3 -) at the cathode (added as catholyte).…”

Groundwater contamination is an ever-growing environmental issue, that has attracted much and undiminished attention for the past half century. Groundwater contamination originates from anthropogenic (e.g. hydrocarbons), natural compounds (e.g. nitrate and arsenic), or both; to tackle these contaminants different technologies have been tested during the years. Recently, bioelectrochemical systems (BESs) have emerged as a potential treatment for groundwater contamination, with in situ applications reported, that showed promising results. Nitrate and hydrocarbons (toluene, phenanthrene, benzene, BTEX and light PAHs) have been successfully removed, due to the interaction of microbial metabolism with poised electrodes, other than physical migration due to the electric field generated in BES. The selection of proper BESs relies on several factors and problems such as complexity of the groundwater, scale-up and energy requirements that need to be taken into account. Modelling efforts could help predict case scenarios and choose an ideal design and approach to solve these issues. In this review, we critically analyze in situ BES applications for groundwater remediation, focusing in particular on the different setups proposed, and we identify and discuss the existing research gaps in the field.

“…MFCs could be employed in the treatment of these recalcitrant pollutants with concomitant bioelectricity generation (Morris and Jin, 2012). The treatment of a mixture of phenanthrene and benzene using two different tubular microbial fuel cells (MFCs) were designed for either in situ and ex situ applications in aqueous systems over long periods (up to 155 days) (Adelaja et al, 2017). Simultaneous removal of the petroleum hydrocarbons (>90 % in term of degradation efficiency) and bromate, used as catholyte (up to 79 %) with concomitant biogenic electricity generation (peak power density up to 6.75 mW m -2 ) were obtained at a hydraulic retention time (HRT) of 10 days for in situ studies.…”

Microbial fuel cells (MFCs) have been demonstrated as a challenging and promising technology towards management of various environmental problems. Bioremediation has been accepted widely as viable option utilizing the naturally inhabited microorganisms, but sometimes the severe low efficiency of the microorganisms and poor controllability limits its application. In this context, MFC technology can be used as a potential means to stimulate bioremediation for effective removal of various pollutants. The special features including energy saving, less sludge and energy production make MFCs as outstanding technology compared to conventional technologies. This article is mainly focused on application of MFCs towards removal of various environmental pollutants viz. antibiotics, synthetic dyes, phenolic compounds, nitrogen based compounds, ethyl acetate, toluene, polycyclic aromatic hydrocarbons, perchlorate, pesticide, sulphur, emerging contaminants, trace organic compounds etc. from aqueous environment. Although the current applications of MFC technology is still at laboratory level, it will definitely prove a great potential towards commercial applications in near future.
