“…In addition to using a single draw solution, a study has examined the performance of multicomponent draw solutions in FO. 78 The water flux of multicomponent inorganic draw solution (0.25 M NaCl + 0.5 M Na 2 SO 4 + 1 M MgCl + 0.25 M KCl) was similar to that of NaCl at the concentration of 1.5 M (16.91 LMH and 17.66 LMH), but sRSF was significantly decreased (0.86 g/L and 1.53 g/L). Currently, no studies have investigated the performance of multicomponent inorganic draw solutes in OsMFCs, so more studies can be conducted accordingly.…”

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.

“…The cleaning process can be either physical/chemical-based. As per experimental results reported in a previous study, , the membrane could be cleaned effectively by flushing and osmotic backwashing. However, in the case of irreversible fouling due to organic biofouling, membrane cleaning by chemicals is also found to be very effective.…”

In this study, a one-dimensional mathematical model was developed for the concentration of tea extract using a forward osmosis (FO) process. The membrane transport parameters were estimated by minimizing the error between the model output and the experimental results. The model equations were solved to predict the FO performance within allowable error limits. Further, a series of process flow sheet simulation studies were performed to investigate the effect of different operating conditions on the overall FO performance. Based on the simulation results, a multicriteria optimization was developed to attain the maximum permeate and minimum specific reverse solute flux (SRSF). Using the best-performing process flow sheet model, the feasibility of seawater and high-concentration reject brine as a draw solution was also investigated for the concentration of tea extract. The high-concentration reject brine (105.17 g L–1) can result in rapid dewatering with minimal SRSF (0.14 g L–1) along with simultaneous seawater dilution (81.38 g L–1).
