“…A recent study investigated the effect of magnetic field direction and strength on the performance of OsMFCs. 79 Under the condition of lower intensity magnetic field, the power generation and water extraction performance of the system are improved. However, there was no significant change in RSF compared with the control group.…”

The osmotic microbial fuel cell (OsMFC) is formed by combining forward osmosis (FO) and microbial fuel cells (MFC). Its excellent performance undoubtedly provided a new research direction for the application of FO and MFCs. However, the reverse solute flux (RSF) in FO also follows. RSF will cause a series of negative effects such as loss of draw solutions, decrease of water flux, and electricity generation. Therefore, inhibition of RSF is very necessary for the practical application of OsMFCs. Currently, there are much research and related reviews on RSF inhibition in FO but few studies on OsMFCs. To provide some new ideas for the inhibition of RSF in OsMFCs, we focused on three aspects: operating conditions, draw solutions, and FO membranes. Existing studies have demonstrated that some strategies are effective in OsMFC, including inhibitory effect of current generation, conventional inorganic draw solutions, membrane materials and orientation, and modified membranes. But there are many more strategies available. Using FO as a reference, strategies such as pressure-assisted osmosis and temperature control may be feasible and need to be investigated further. In the future, the inhibition or utilization of RSF can further improve the reactor performance and promote the early practical application of OsMFCs.

“…To address this issue, a comparative investigation was recently performed on the influence of a solenoid magnetic field (SOMF) direction on the performance of an osmotic microbial fuel cell (OMBFC). [171] This latter is a special kind of MBFC with an innovative technology that can replace conventional ion (anion or cation) exchange membrane with forward osmosis (FO) membrane in bio-electrochemical systems. The comparison experiment on the positive effect of low-frequency SOMF was carried out by changing the water flow and SOMF lines relative to the flow direction (Figure 13b).…”

“…In this case, the performance of OMBFC was higher when the direction was antiparallel than in parallel. [171] In addition, water flux in the FO process facilitates ion transport and lower membrane resistance and consequently OMBFC can produced more electricity than conventional MBFCs. [171]…”

Magnetically stimulated bio‐and electrochemical systems have gained increasing importance in recent years due to their enhanced sensitivity and selectivity, improved spatial control, and ability to operate in complex environments, offering significant advantages over conventional systems. Essentially, this review provides a comprehensive and informative survey about the state‐of‐art as well as the recent efforts and applications made in the past decade, with a focus on new functional magnetic materials and nano‐architectonic interfaces that have led to promising advances in biosensors, biofuel cells, and their integration into devices. Future directions and perspectives are also discussed.

“…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.…”

Recovery of Nutrients from Residual Streams Using Ion-Exchange Membranes: Current State, Bottlenecks, Fundamentals and Innovations

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.
