“…The highest power density of the OsMFC was found to be 3.42 ± 0.18 W/m 3 , which was 18.7% higher than that of the stand-alone MFC (2.78 ± 0.82 W/m 3 ). Under varied operating circumstances, the findings of the experiment revealed that water-fluxfacilitated proton advection was more essential than NPC-flux-promoted countercurrent proton exchange in regulating the power production in an OsMFC [48].…”

Nowadays, the world is experiencing an energy crisis due to extensive globalization and industrialization. Most of the sources of renewable energy are getting depleted, and thus, there is an urge to locate alternative routes to produce energy efficiently. Microbial fuel cell (MFC) is a favorable technology that utilizes electroactive microorganisms acting as a biocatalyst at the anode compartment converting organic matter present in sewage water for bioelectricity production and simultaneously treating wastewater. However, there are certain limitations with a typical stand-alone MFC for efficient energy recovery and its practical implementation, including low power output and high cost associated with treatment. There are various modifications carried out on MFC for eliminating the limitations of a stand-alone MFC. Examples of such modification include integration of microbial fuel cell with capacitive deionization technology, forward osmosis technology, anaerobic digester, and constructed wetland technology. This review describes various integrated MFC systems along with their potential application on an industrial scale for wastewater treatment, biofuel generation, and energy production. As a result, such integration of MFCs with existing systems is urgently needed to address the cost, fouling, durability, and sustainability-related issues of MFCs while also improving the grade of treatment received by effluent.

“…Just as in the case of traditional methods, biochemical methods are mainly used to stabilize wastewater and convert nutrients into forms convenient for their further processing. Meanwhile, the use of osmotic [ 89 , 90 ], microfiltration and ultrafiltration polymeric and ceramic membranes [ 91 , 92 , 93 ], as well as reverse osmosis [ 94 ], nanofiltration [ 95 , 96 ], ion-exchange [ 86 ], or gas separation [ 97 ] membranes in MBRs and MMFCs allows selective and reagent-free recovery of target components even if their concentrations in liquid or gaseous phases are low. MMFCs combine two processes: the transformation of nutrients from complex organic substances into simple inorganic forms and the generation of electricity through the simultaneous implementation of redox reactions involving microorganisms.…”

“…As shown by Xue et al [ 90 ], the integration of FO into MFC allows a 19% increase in power density in osmotic microbiological cells (OMFC) due to the water-flux-facilitated proton transfer. The application of a magnetic field promotes the formation of a biofilm on the MFC anode and can increase the current density by 20–30% in the case of OMFC [ 112 ].…”

“…FO, MF, UF, gas separation and, especially, IEM in MBR, MMFC and other bioelectrochemical systems, as well as MCDI and ED modules, are subjected to intense chemical and biochemical fouling [ 90 , 211 , 212 ], which is well known and studied among “bottlenecks” of electromembrane systems and integrated with them processes. Indeed, the nutrient recovery is carried out from liquids that contain a large number of microorganisms or organic and inorganic substances that are a nutritional medium.…”

The review describes the place of membrane methods in solving the problem of the recovery and re-use of biogenic elements (nutrients), primarily trivalent nitrogen NIII and pentavalent phosphorus PV, to provide the sustainable development of mankind. Methods for the recovery of NH4+ − NH3 and phosphates from natural sources and waste products of humans and animals, as well as industrial streams, are classified. Particular attention is paid to the possibilities of using membrane processes for the transition to a circular economy in the field of nutrients. The possibilities of different methods, already developed or under development, are evaluated, primarily those that use ion-exchange membranes. Electromembrane methods take a special place including capacitive deionization and electrodialysis applied for recovery, separation, concentration, and reagent-free pH shift of solutions. This review is distinguished by the fact that it summarizes not only the successes, but also the “bottlenecks” of ion-exchange membrane-based processes. Modern views on the mechanisms of NH4+ − NH3 and phosphate transport in ion-exchange membranes in the presence and in the absence of an electric field are discussed. The innovations to enhance the performance of electromembrane separation processes for phosphate and ammonium recovery are considered.

Increasing populations and urbanization put a lot of pressure on freshwater supplies and use. The increased demand for drinking water can be met by using seawater as a source of freshwater. Desalination and wastewater treatment have been energy-and time-consuming processes in recent years. Microbial desalination cells (MDCs) have gained considerable attention as an emerging technology because of their ability to treat wastewater, desalinate seawater, and produce electricity and value-added products. The efficiency and performance of this technology are affected by numerous factors. In this study, the effect of membranes on the efficiency and performance of this technology is examined. Anionic and cationic, carbon nanotube (CNT), bipolar and osmotic membranes were investigated. Anionic and cationic membranes, as well as their modifications, significantly influence microbial desalination cells.CNT-based membranes have shown significant improvements in water permeability, desalination capacity, strength, anti-fouling, and energy efficiency compared to other membranes. Bipolar membranes prevent the pH of the anode chamber from decreasing, which is essential for MDC operation. The use of FO membranes in microbial desalination cells still faces challenges; for instance, fouling is more likely in FO membranes than ion-exchange membranes, resulting in higher internal resistance and decreased water flux. MDC technology will require research into membrane fouling, electron transfer kinetics, material feasibility, microbial growth, and catalyst durability to be scaled and sustainable. As part of the feasibility study, the performance and stability of the reactor must also be examined.
