“…Due to its advantages in water treatment, such as a lack of secondary contaminants, high selectivity, high separation efficiency, and superior stability, membrane technology has received a lot of attention [ 7 , 8 , 9 , 10 ]. As shown in Figure 1 , membrane separation techniques include pressure-driven membrane processes (microfiltration, ultrafiltration, nanofiltration, reverse osmosis), low-temperature-driven membrane processes, and several other processes used in special fields (forward osmosis, membrane bioreactor, heavy metal ion adsorption, oil–water separation, and photocatalysis), and some of these technologies have recently been widely used for water separation and purification [ 11 , 12 , 13 , 14 , 15 , 16 ]. The selection of materials and preparation methods for these membranes determines the performance and economic advantages of the nanofiber-membrane-based water treatment process.…”

In the field of water purification, membrane separation technology plays a significant role. Electrospinning has emerged as a primary method to produce nanofiber membranes due to its straightforward, low cost, functional diversity, and process controllability. It is possible to flexibly control the structural characteristics of electrospun nanofiber membranes as well as carry out various membrane material combinations to make full use of their various properties, including high porosity, high selectivity, and microporous permeability to obtain high-performance water treatment membranes. These water separation membranes can satisfy the fast and efficient purification requirements in different water purification applications due to their high filtration efficiency. The current research on water treatment membranes is still focused on creating high-permeability membranes with outstanding selectivity, remarkable antifouling performance, superior physical and chemical performance, and long-term stability. This paper reviewed the preparation methods and properties of electrospun nanofiber membranes for water treatment in various fields, including microfiltration, ultrafiltration, nanofiltration, reverse osmosis, forward osmosis, and other special applications. Lastly, various antifouling technologies and research progress of water treatment membranes were discussed, and the future development direction of electrospun nanofiber membranes for water treatment was also presented.

“…The separation of EDCs using membrane technology is one of the promising economical techniques and suitable for e cient puri cation due to its facile synthesis, ease of operation, zero chemical supplements or phase changes, comparatively low energy requirement, and superior separation performance [9,10]. Recently, the UF membrane in particular has greater potential in the water treatment process and is regarded as an e cient barrier for suspended substances, colloids, microorganisms, and particles, and has been increasingly used for drinking water supply owing to lower energy requirements, low cost, e cient performance, and a reduced operating pressure [11]. Thus, the UF technique is a suitable option for drinking water puri cation.…”

Recently, frequent discharge of water-ladened emerging organic pollutants such as Bisphenol A has generated serious concern owing to its harmful effects on public safety and the ecological environment. Hematite nanoparticles (Fe 2 O 3 ) were synthesized via the sol-gel auto-combustion procedure and utilized as a nano ller to fabricate a PVDF-PEG/Fe 2 O 3 nanocomposite hollow bre membrane with enhanced antifouling properties. A series of membranes comprising various loadings (1.0-2.0 wt.%) of Fe 2 O 3 NPs were fabricated through the phase inversion technique and thoroughly analyzed. The developed Fe 2 O 3membrane bres were thoroughly characterized. The performance of the membrane bres was investigated through permeation ux, BPA rejection, as well as antifouling characteristics. Based on the results obtained, the resultant nanocomposite membrane bres exhibited superior performance in comparison with the pristine bre. Also, the nanocomposite membrane with 1.5 wt.%-Fe 2 O 3 NPs exhibited remarkable performance with − 43.7 mV, 56.3º, 191.85 L/m 2 -h, 86.7%, and 12% of negatively charged zeta potential, least contact angle, water permeation ux, BPA rejection, and minimum weight loss, respectively. Besides, the 1.5 wt-Fe 2 O 3 NPs nanocomposite membrane demonstrated superior antifouling performance after the third ltration, accomplishing a higher percent of FRR (77.35%) along with RFR of 21.29%, respectively. Hence, based on the performance of the fabricated hollow-bre membranes loaded with Fe 2 O 3 NPs, e cient antifouling membranes was achieved which can be suitably applied in the puri cation of industrial wastewater.
