“…The development of excellent membranes with simpler and more economical production processes has more practical significance. Some membrane modification technologies focus on the optimization of the FO membrane permeability coefficient, , but the increase of water flux is often accompanied by the increase of RSF based on the trade-off relation between water permeability and water/salt selectivity. , Therefore, the next research direction should focus on how to promote the promotion and application of high-quality membranes instead of blindly developing different novel FO membranes.…”

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.

“…; despite little covering TFC. [71,72] For instance, the use of a small amount of polyvinylpyrrolidone (PVP) in casting solution and change of coagulation bath temperature from 0 °C to 25 °C facilitated macrovoid formation and in turn water flux. In contrast, higher PVP concentration (6 wt% in casting solution) or coagulation temperature (50 °C) lowered water flux, due to reduction in macrovoids or membrane hydrophilicity.…”

Semipermeable membranes are the core elements for membrane water desalination technologies such as commercial reverse osmosis (RO) process and emerging forward osmosis (FO) process. Structural and chemical properties of the semipermeable membranes determine water flux, salt rejection, fouling resistance, and chemical stability, which greatly impact energy consumption and costs in osmosis separation processes. In recent years, significant progress has been made in the development of high-performance polymer and polymer composite membranes for desalination applications. This paper reviews recent advances in different polymer-based RO and FO desalination membranes in terms of materials and strategies developed for improving properties and performances.
