“…The increase in the mass transfer coefficient reduces the influence of ICP, which is conducive to the extraction of clean water. , The increase of forward osmotic flux of water molecules also inhibited RSF [Figure (b)]. If the temperature on the draw solution side is low, the viscosity of the draw solution and the diffusion resistance is high, the reverse diffusion of solutes in the draw solution slows down, and RSF is inhibited . Therefore, there is a certain temperature difference between the feed and draw solution (the temperature of the feed solution is higher than that of the draw solution), which does not affect the extraction of clean water and can inhibit RSF.…”

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.
