“…The excellent mechanical strength and other advantages (as shown in Table 1) of PSf membrane suggest this is a good candidate for wastewater treatment systems, textile dyeing, and desalination. PSf membranes require surface modification in order to enhance hydrophilicity and water permeation [24]. The incorporation of hydrophilic nanoparticles in the PSf membrane can improve antifouling properties and increase the flux rate.…”

“…The incorporation of hydrophilic nanoparticles in the PSf membrane can improve antifouling properties and increase the flux rate. Peechmani et al [24] fabricated hybrid PSf/zinc oxide (ZnO) BHFMs to increase flux and improve hydrophilicity. The BHFMs were prepared with different concentrations of ZnO nanoparticles.…”

“…A braid hollow fiber membrane (BHFM) is fabricated by coating a thin film on the surface of tubular braid (i.e., reinforced fiber). The presence of braid support increases the flux of ultrafiltration/microfiltration due to the thinner thickness of the selective layer, thanks to tolerating relatively higher pressure compared with the typical HFM [4,[21][22][23][24]. The first studies in reinforced HFMs are related to the patents.…”

“…The braid support absorbs the molecules of water due to the porous structure. The thin separation layer of the BHFM also contributed to the water flux enhancement because of lower thickness compared to self-support HFMs [24]. Chen et al [28] reported that the flux of braid PMIA-BHFMs was higher than the PMIA-HFMs.…”

“…BHFMs are fabricated by two spinning methods: electrospinning method and nonsolvent-induced phase inversion (NIPS) based on the dry-wet spinning. Based on the literature, membranes prepared by the NIPS method based on the dry-wet spinning process are more common and have higher water flux due to thin separation layers [24]. As shown in Figure 1, the tube braid (like the bore fluid injection in the fabrication of common HFMs) is inserted through the middle of the spinneret.…”

Hollow fiber membranes (HFMs) possess desired properties such as high surface area, desirable filtration efficiency, high packing density relative to other configurations. Nevertheless, they are often possible to break or damage during the high-pressure cleaning and aeration process. Recently, using the braid reinforcing as support is recommended to improve the mechanical strength of HFMs. The braid hollow fiber membrane (BHFM) is capable apply under higher pressure conditions. This review investigates the fabrication parameters and the methods for the improvement of BHFM performance.

Tight ultrafiltration (UF) has increasingly been developed to overcome the low selectivity of conventional UF membranes towards soluble contaminants. In this work, a tight structure of polysulfone-based (PSf) UF membrane was prepared by blending PSf with polyethylene glycol (PEG400), ZnO nanoparticle (ZnO-Np), and acetone (Ac) in dimethylacetamide (DMAc). The influences of Ac/DMAc ratio (1: 15 to 1:25) and PEG400 concentration (0-25 wt%) on the binodal curve of the polymer solution, characteristics, and performances of the UF membrane were studied. The membrane performances were investigated by observing the permeate flux and dye rejection during real textile wastewater treatment. The binodal curves are close to the polymer line, which means that rapid demixing occurred after the casted solution was immersed in the coagulation bath. Based on FTIR analysis, PEG400 and ZnO-Np were partially entrapped in the UF membrane structure. Over 90% of color removal at a permeate flux of 72 L.m À2 .h À1 could be achieved when the Ac/DMAC ratio was 1:12. The tight-UF membrane removed TDS and Naphthol AS by 74.5% and 92.8%, respectively. Since the experimental result showed a high contaminants removal, the tight-UF could be used as clean technology to produce clean water for water reuse purposes at low energy requirements.

In this study, the nanoparticles (NPs) of ZnO and Co2+ ions doped ZnO (doped ZnO) were incorporated into a matrix of polysulfone (PSf) membranes to enhance their surface properties prepared using a simple wet phase inversion technique. The hybrid PSf membranes were fabricated with 0.5 wt. % of ZnO and doped ZnO NPs. These membranes were characterized using XRD, TGA, FESEM-EDX, and salt rejection performance. The hydrophilicity of PSf membranes was improved by adding of ZnO and doped ZnO NPs which showed a decrease in contact angle values from 82° to 62° with an increased flux with water. Among the prepared membranes, doped ZnO NPs showed the highest salt rejection for both sodium chloride (NaCl) and sodium sulfate (Na2SO4) compared to pure PSf and PSf with ZnO NPs which confirm the improvement contact angle and water permeability. Overall, the results of this study showed that embedding a small amount of Co2+ ions doped ZnO NPs with PSf has significant potential to be applied in industrial-scale membrane applications.
