“…It was reported that MFCs could act as a down-stream process to treat the excess sludge from a conventional aerobic MBR (Su et al, 2013). Compared to a conventional MBR, the combine system reduced the sludge yield by 5.1% and showed fouling mitigation through reducing the loose-bound extracellular polymeric substances by 22%, a major contributor to membrane fouling.…”

Bioelectrochemical systems (BES) represent an energy-efficient approach for wastewater treatment, but the effluent still requires further treatment for direct discharge or reuse. Integrating membrane filtration in BES can achieve high-quality effluents with additional benefits. Three types of filtration membranes, dynamic membrane, ultrafiltration membrane and forward osmosis membrane that are grouped based on pore size, have been studied for integration in BES. The integration can be accomplished either in an internal or an external configuration. In an internal configuration, membranes can act as a separator between the electrodes, or be immersed in the anode/cathode chamber as a filtration component. The external configuration allows BES and membrane module to be operated independently. Given much progress and interest in the integration of membrane filtration into BES, this paper has reviewed the past studies, described various integration methods, discussed the advantages and limitations of each integration, and presented challenges for future development.

“…Novel membrane types that are designed to pose minimum fouling propensity is also effective Kharraz et al, 2015;Marbelia et al, 2016). Performance of MBR can also be further enhanced through process integration, such as with microbial fuel cell Ren et al, 2014;Su et al, 2013) or with photobioreactor (Gao et al, 2016;Marbelia et al, 2014). MBR technology also requires an upgrade in order to treat emerging contaminants such as pharmaceutical compounds (Melvin & Leusch, 2016;Prasertkulsak et al, 2016).…”

Membrane bioreactors (MBRs) have recently become widely accepted as an advanced technology for treatment of domestic and industrial wastewaters. The objective of this review is to provide overview on MBR technology for wastewater treatment application. It includes discussions on the fundamental, core problems (membrane fouling), recent effective development approach (dynamic filtration systems) and future research direction of MBRs. Since MBRs integrate a conventional activated sludge process with membrane filtration, and both fundamental aspects are discussed first. Later, a comprehensive discussion about membrane fouling, the main problems in MBR, is provided, including fouling control strategies. The discussion on the MBR membranes and relation between membrane properties and MBR performance is also provided. This review also includes one of the most promising MBR technologies that specifically design to manage membrane fouling: dynamic filtration systems. Lastly, insight into an approach to address MBRs challenges and recent research and developments are provided.

“…In order to fully integrate both MFC-MBR system, Su et al [82] fed activated sludge from MBR to MFC for bioelectricity generation while the non-consumed sludge in MFC was recycled back to MBR to reduce sludge production as illustrated in Figure 13. Excellent COD and ammonia removal (more than 90 %) was successfully achieved with sludge reduction was 5.1 % higher than that of the conventional MBR.…”

“…This novel self-sustained EMBR configuration allows maximum sludge reduction and energy recovery. self-sustained EMBR [82] In most of the previous research, IEM was used to separate anodic chamber and cathodic chamber. Nevertheless, the use of IEM increases the overall internal resistance and the overall cost of the system [75].…”

Membrane fouling is the major challenges that hinders the widespread application of membrane bioreactor (MBR). Recently, application of electricity in electrically-enhanced MBR (EMBR) to suppress membrane fouling has gained much attention among research communities. This paper presents an overview of developments on EMBR for fouling suppression in wastewater treatment. The flow of electricity has stimulated several electrokinetic processes including electrophoresis/electrochemical process, and electrocoagulation which are the major fouling suppression mechanisms employed in EMBR. In electrophoresis, the membrane fouling is suppressed by the increased electrorepulsive force between negatively-charged foulants and cathode membrane under the influence of an electric field. Besides, electric field also induces simultaneous electrochemical oxidation and reduction which generate chemicals to degrade pollutant in wastewater. On top of that, use of active anode is reminiscent of electrocoagulation which produces cation coagulants in EMBR that capable to neutralize charge of the foulants and promotes flocs formation. This increases flocs size and sedimentation rate thereafter reduces adhesion of foulants on the membrane surface. Lastly, bioelectricity generation of microbial fuel cell (MFC) integrated with MBR to attain self-sustained EMBR has been studied. Self-sustained EMBR combines the advantages of MFC and MBR in treating wastewater and energy recovery simultaneously. Overall, it is evidenced that MBR and electrokinetic processes have a synergetic enhancement effect in EMBR system.
