“…[100] The efforts to improve the TFC membranes often concern two aspects, namely, the substrate structure and the hydrophilicity [112,113]. Wei et al [90] prepared PA-TFC FO membranes with a tailored substrate structure by first producing PSf substrates with a finger-like pore structure by phase inversion, and then synthesizing polyamide active layers by interfacial polymerization.…”

Forward osmosis (FO) is an evolving membrane separation technology for water treatment and reclamation. However, FO water treatment technology is limited by factors such as concentration polarization, membrane fouling, and reverse solute flux. Therefore, it is of a great importance to prepare an efficient high-density porous membrane and to select an appropriate draw solute to reduce concentration polarization, membrane fouling, and reverse solute flux. This review aims to present a thorough evaluation of the advancement of different draw solutes and membranes with their effects on FO performance. NaCl is still widely used in a large number of studies, and several general draw solutes, such as organic-based and inorganic-based, are selected based on their osmotic pressure and water solubility. The selection criteria for reusable solutes, such as heat-recovered gaseous draw, magnetic field-recovered MNPs, and electrically or thermally-responsive hydrogel are primarily based on their industrial efficiency and energy requirements. CA membranes are resistant to chlorine degradation and are hydrophilic, while TFC/TFN exhibit a high inhibition of bio-adhesion and hydrolysis. AQPs are emerging membranes, due to proteins with complete retention capacity. Moreover, the development of the hybrid system combining FO with other energy or water treatment technologies is crucial to the sustainability of FO.

“…Membrane development should consider the intrinsic transport phenomena occurring during FO, which are concentration polarization and reverse solute diffusion. 193 Also, membrane fouling during the large-scale and long-term operation of FO, especially when using problematic feed solutions, is a huge issue that needs to be addressed. While FO is highly regarded as a low-fouling process due to the reversibility of the fouling layer formed onto the FO membrane compared to those in pressure-driven membrane processes, 194 fouling can still inevitably occur during the FO process and effectively decrease membrane performance and increase costs.…”

“…To date, there are several articles that have reviewed different aspects of FO, such as methods and process development [ 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ], applications [ 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 ], fouling behaviors [ 24 , 26 , 55 , 56 , 57 , 58 , 59 ], draw solution characteristics [ 17 , 18 , 19 , 20 , 21 , 60 , 61 ], and energy considerations [ 15 , 62 , 63 , 64 , 65 , 66 , 67 ]. There are, however, few studies that provide a focused overview of the different support layer design strategies [ 25 , 68 ] along with the diverse transport property evaluation methodologies [ 69 ] that are discussed in the literature. This review will critically analyze the various support layer fabrication techniques that are consequential in determining the performance of FO membranes, primarily via reduced

-values.…”

This article reviews the many innovative strategies that have been developed to specifically design the support layers of forward osmosis (FO) membranes. Forward osmosis (FO) is one of the most viable separation technologies to treat hypersaline wastewater, but its successful deployment requires the development of new membrane materials beyond existing desalination membranes. Specifically, designing the FO membrane support layers requires new engineering techniques to minimize the internal concentration polarization (ICP) effects encountered in cases of FO. In this paper, we have reviewed several such techniques developed by different research groups and summarized the membrane transport properties corresponding to each approach. An important transport parameter that helps to compare the various approaches is the so-called structural parameter (-value); a low -value typically corresponds to low ICP. Strategies such as electrospinning, solvent casting, and hollow fiber spinning, have been developed by prior researchers—all of them aimed at lowering this -value. We also reviewed the quantitative methods described in the literature, to evaluate the separation properties of FO membranes. Lastly, we have highlighted some key research gaps, and provided suggestions for potential strategies that researchers could adopt to enable easy comparison of FO membranes.
