"Microbial Fuel Cell Fed by Barnett Shale Produced Water: Power Production by Hypersaline Autochthonous Bacteria and Coupling to a Desalination (Capacitive Deionization) Unit." <i>Biochemical Engineering Journal,</i> 117, no. A (2017) Elsevier: 87-91. http://dx.doi.org/10.1016/j.bej.2016.09.013.https://hdl.handle.net/1911/93969Hydraulic fracturing for oil and gas production can generate large volumes of highly saline produced waters that pose a significant disposal challenge and a potential opportunity for reuse. Here, we report on a microbial fuel cell (MFC) fed with produced water (Barnett Shale), which produced power (47 mW/m2) and accomplished a COD removal efficiency of 68% (influent COD 10,520 ± 1340 mg/L). Bacterial population analysis showed two autochthonous halophilic species colonizing the anode, H. praevalens and M. hydrocarbonoclasticus. In addition, we demonstrated that hypersaline MFCs (100 g/L NaCl) can produce electricity to power a capacitive deionization (CDI) device for desalination, with a salt adsorption capacity of up to 40 mg of salt per g of carbon electrode. This is the first report of a MFC operating with hypersaline produced water, and illustrates the potential to couple MFCs with CDI to enable desalination and reuse of hypersaline wastewaters.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
