“…FO is an emerging process that uses FO membrane to separate water from feed solution (e.g., higher water chemical potential) to draw solution (e.g., lower water chemical potential) by natural gradient osmosis [ 310 ]. As a result, diluted draw solution and concentrated feed solution will be obtained.…”

The aggravation of environmental problems such as water scarcity and air pollution has called upon the need for a sustainable solution globally. Membrane technology, owing to its simplicity, sustainability, and cost-effectiveness, has emerged as one of the favorable technologies for water and air purification. Among all of the membrane configurations, hollow fiber membranes hold promise due to their outstanding packing density and ease of module assembly. Herein, this review systematically outlines the fundamentals of hollow fiber membranes, which comprise the structural analyses and phase inversion mechanism. Furthermore, illustrations of the latest advances in the fabrication of organic, inorganic, and composite hollow fiber membranes are presented. Key findings on the utilization of hollow fiber membranes in microfiltration (MF), nanofiltration (NF), reverse osmosis (RO), forward osmosis (FO), pervaporation, gas and vapor separation, membrane distillation, and membrane contactor are also reported. Moreover, the applications in nuclear waste treatment and biomedical fields such as hemodialysis and drug delivery are emphasized. Subsequently, the emerging R&D areas, precisely on green fabrication and modification techniques as well as sustainable materials for hollow fiber membranes, are highlighted. Last but not least, this review offers invigorating perspectives on the future directions for the design of next-generation hollow fiber membranes for various applications. As such, the comprehensive and critical insights gained in this review are anticipated to provide a new research doorway to stimulate the future development and optimization of hollow fiber membranes.

Polysaccharides of Dendrobium officinale (DOP) need to be dehydrated and concentrated after extraction for further application. They are usually concentrated by thermal evaporation which consumes great energy. However, high viscosity of DOP makes the concentration more difficult even using non-thermal membrane technologies such as nanofiltration (NF) or reverse osmosis (RO). In this study, effects of process conditions, such as membrane orientations, draw solutions and their concentrations, and flowrate on forward osmosis (FO) concentration of viscous DOP were studied. Active layer to feed solution mode, cross flowrate at 240 mL min −1 , and draw solution of 3 M NaCl have been found as the optimal conditions. Foulants on the membrane surface with loose structure could be easily cleaned and removed by hydraulic flushing. DOP concentrated by FO achieved almost 1.3 times at the same time compared with that in NF and RO. DOP could be further concentrated for 1.5 folds at longtime without significant decrease in water flux. In addition, slight reverse solutes in FO process could reduce the viscosity of high viscous DOP, which was good for concentration. Accordingly, FO is a potential technology for concentration of high viscous polysaccharides such as DOP.

“…The forward osmosis (FO) membrane process is an advanced technology for seawater desalination and wastewater reuse. , Unlike the pressure-driven film processes, FO is an osmotic pressure-driven process operated with no or a low hydraulic pressure. − By using the salinity gradients, it can generate clean water from polluted raw water to alleviate the freshwater shortage. Compared with the pressure-driven membrane processes, FO has a higher water-recovery efficiency, a lower membrane fouling tendency, and a higher energy-utilizing efficiency. , Besides seawater desalination and wastewater recovery, FO also has a great potential of application in food processing, pharmaceutical intermediate enrichment, and osmotic energy generation. − However, in current use, the permeability, solute repellency, and persistent chlorine resistance of FO membranes still need to be improved for the water-cleaning process. , Generally, the structure and components of FO membrane are very important for governing their performance.…”

Low permeability and chlorine resistance of normal thin-film composite (TFC) membranes restrict their practical applications in many fields. This study reports the preparation of a high chlorine-resistant TFC membrane for forward osmosis (FO) by incorporating corn stalk-derived N-doped carbon quantum dots (N-CQDs) into the selective polyamide (PA) layer to construct a polydopamine (PDA) sub-layer (PTFCCQD). Membrane modification is characterized by surface morphology, hydrophilicity, Zeta potential, and roughness. Results show that TFCCQD (without PDA pretreatment) and PTFCCQD membranes possess greater negative surface charges and thinner layer-thickness (less than 68 nm). With N-CQDs and PDA pretreatment, the surface roughness of the PTFCCQD membrane decreases significantly with the co-existence of microsized balls and flocs with a dense porous structure. With the variation of concentration and type of draw solution, the PTFCCQD membrane exhibits an excellent permeability with low J (reverse salt flux)/J (water flux) values (0.1-0.25) due to the enhancement of surface hydrophilicity and the shortening of permeable paths. With 16,000 ppm·h chlorination, reverse salt flux of the PTFCCQD membrane (8.4 g m–2 h–1) is far lower than those of TFCCQD (136.2 g m–2 h–1), PTFC (127.6 g m–2 h–1), and TFC (132 g m–2 h–1) membranes in FO processes. The decline of salt rejection of the PTFCCQD membrane is only 8.2%, and the normalized salt rejection maintains 0.918 in the RO system (16,000 ppm·h chlorination). Super salt rejection is ascribed to the existence of abundant NH bonds (N-CQDs), which are preferentially chlorinated by free chlorine to reduce the corrosion of the PA layer. The structure of the PA layer is stable during chlorination also due to the existence of various active groups grafted on the surface. This study may pave a new direction for the preparation of durable biomass-derivative (N-CQD)-modified membranes to satisfy much more possible applications.
