“…BES emerges as an attractive treatment concept for energy-efficient wastewater treatment with direct electricity production from wastewater through microbial oxidation of organic contaminants (Wang and Ren 2013). A typical BES contains anode and cathode electrodes, and can be used to generate electricity, produce hydrogen, desalinate saline water, or accomplish other functions.…”

“…To produce higher-value products such as pure organic compounds, electrons are used by microorganisms in the cathode to achieve microbial electrosysthesis (Rabaey and Rozendal 2010). More details about BES, including the substrates, materials, microbiology, and different system can be found in various 21 review papers , Logan et al 2006, Rabaey and Verstraete 2005, Schröder et al 2015, Wang and Ren 2013.…”

“…Ion exchange membranes such as cation exchange membrane (CEM) or anion exchange membrane (AEM) is used as the separator between the anode and the cathode, and there have also been membrane-less BES is a microbial fuel cell (MFC), which can generate electricity directly from wastewater . MFCs can be modified to accomplish various functions such as hydrogen production, desalination, and heavy metal removal (Figure 1.2A) Rabaey 2012, Wang andRen 2013). In a microbial electrolysis cell (MEC), hydrogen gas or other value-added chemicals can be produced with a small amount of external power input (Figure 1.2B) (Cheng et al 2009, Logan et al 2008a.…”

(academic)Recovering valuable resources from wastewater will transform wastewater management from a treatment focused to sustainability focused strategy, and creates the need for new technology development. An innovative treatment concept -osmotic bioelectrochemical system (OsBES), which is based on cooperation between bioelectrochemical systems (BES) and forward osmosis (FO), has been introduced and studied in the past few years. An OsBES can accomplish simultaneous treatment of wastewater and recovery of resources such as nutrient, energy, and water (NEW). The cooperation can be accomplished in either an integrated (osmotic microbial fuel cells, OsMFC) or coupled (microbial electrolysis cell-forward osmosis system, MEC-FO) configuration.In OsMFC, higher current generation than regular microbial fuel cell (MFC) was observed, resulting from the lower resistance of FO membrane. The electricity generation in OsMFC could greatly inhibit the reverse salt flux. Besides, ammonium removal was successfully demonstrated in OsMFC, making OsMFCs a promising technology for "NEW recovery" (NEW: nutrient, energy and water). For the coupled OsBES, an MEC-FO system was developed. The MEC produced an ammonium bicarbonate draw solute via recovering ammonia from synthetic organic solution, which was then applied in the FO for extracting water from the MEC anode effluent. The system has been advanced with treating landfill leachate. A mathematical model developed for ammonia removal/recovery in BES quantitatively confirmed that the NH4 + ions serve as effective proton shuttles across cation exchange membrane (CEM). Resource Recovery by Osmotic Bioelectrochemical Systems towards Sustainable Wastewater TreatmentMohan Qin Abstract (general audience)Nowadays, wastewater is no longer considered as waste. Instead, it is a pool for different kinds of resources, such as nutrient, energy, and water (NEW). Various technologies were developed to achieve NEW recovery from wastewater. A novel concept, osmotic bioelectrochemical system (OsBES) has been introduced and studied in the past few years. OsBES is based on two technologies: bioelectrochemical systems (BES) and forward osmosis (FO); and the corporation between these two technologies could accomplish simultaneous wastewater treatment and resource recovery. We investigated two kinds of OsBES: one is osmotic microbial fuel cells (OsMFC), and the other is microbial electrolysis cell-forward osmosis system (MEC-FO). For OsMFC, a mathematical model was built to understand the internal resistance, which will affect the current generation according to Om's law (I=U/R). The salt transport across the cation exchange membrane (CEM) is related to the current generation. The ion transport, especially ammonium/ammonia transport, across CEM membrane in BES was modelled, which will help the BES design and operation for ammonia recovery systems. The system performance for wastewater treatment and resource recovery in MEC-FO was fully investigated with both synthetic wastewater and landfill leach...

“…MDCs are derived from MFCs by placing AEM and CEM between anode and cathode, creating a middle chamber for water desalination [80] (Figure 3). To maintain electroneutrality, the electric potential gradient generated by exoelectrogenic bacteria drives cations and anions in the saline solution to migrate through CEM and AEM into the cathode chamber and anode chamber, respectively [81], thereby achieving desalination.…”

Bioelectrochemical systems (BES) are a newly emerged technology for energy-efficient water and wastewater treatment. Much effort as well as significant progress has been made in advancing this technology towards practical applications treating various types of waste. However, BES application for agriculture has not been well explored. Herein, studies of BES related to agriculture are reviewed and the potential applications of BES for promoting sustainable agriculture are discussed. BES may be applied to treat the waste/wastewater from agricultural production, minimizing contaminants, producing bioenergy, and recovering useful nutrients. BES can also be used to supply irrigation water via desalinating brackish water or producing reclaimed water from wastewater. The energy generated in BES can be used as a power source for wireless sensors monitoring the key parameters for agricultural activities. The importance of BES to sustainable agriculture should be recognized, and future development of this technology should identify proper application niches with technological advancement.

“…Electrochemically active microorganisms (i.e., exoelectrogens) consume organics in wastewater and respire by releasing electrons extracellularly, and the anode electrode serves as the main electron acceptor (Lovley, 2012). The fact that oxidation and reduction reactions are separate and controllable makes BES a versatile research platform for various functions, such as the removal of nutrients, organic pollutants and heavy metals (Kelly and He, 2014;Wang and Ren, 2013;Zeng et al, 2015;Zhang and Angelidaki, 2014). However, the fate of ARBs and ARGs in BES has not yet been reported to our knowledge.…”
