“…The mixed-matrix PSF membranes showed a higher % FRR than the pristine PSF membranes at 6.25 bars due to the presence of composite particles on the PSF matrix, as ZnO and GO enhance the antifouling activity of membranes [ 32 , 33 , 34 ]. Between the two mixed-matrix PSF membranes CP and MCP, MCP had an FRR of 0.78, which was higher than CP (0.57) at 6.25 bar due to the presence of iron oxide in the composite particles in addition to GO and ZnO; iron oxide enhanced the membrane’s hydrophilicity and antifouling activity [ 35 ]. The lower FRR of MCP, compared with CP, at a lower pressure value could be due to CP having a higher water flux than MCP at lower pressure levels.…”

Membrane fouling is a major drawback in the membrane filtration industry for water treatment. Mixed-matrix membranes (MMMs) are well known for their enhanced antifouling and antibacterial properties, which could offer potential benefits for membrane filtration processes in the water treatment field. In this work, three electrospun nanofibrous MMMs (P, CP, and MCP, which were, respectively, the pristine polysulfone membrane and mixed-matrix membranes (MMMs) consisting of GO–ZnO and GO–ZnO–iron oxides) were studied for antifouling and antibacterial properties with respect to the arsenic nanofiltration process. The effects of these composites on the antifouling behaviour of the membranes were studied by characterising the bovine serum albumin (BSA) protein adsorption on the membranes and subsequent analysis using microscopic (morphology via scanning electron microscopy) and Brunauer–Emmett–Teller (BET) analyses. The antibacterial properties of these membranes were also studied against Gram-positive Staphylococcus aureus (S. aureus) and Gram-negative Escherichia coli (E. coli). The composite nanoparticle-incorporated membranes showed improved antifouling properties in comparison with the pristine polysulfone (PSF) membrane. The excellent antimicrobial properties of these membranes make them appropriate candidates to contribute to or overcome biofouling issues in water or wastewater treatment applications.

“…Macrovoid formation was observed in cross‐sectional morphology of both SPEEK/TiZr and SPEEK/TiZn MMMs. This may be due to the addition of nano metal oxides, which has induced faster solvent and nonsolvent exchange rate (instantaneous demixing) during PES rigidification 31 . From the EDS mapping of the cross‐sectional micrographs, good dispersion of nanocomposites Ti‐Zr and Ti‐Zn is noticed in MMMs of TiZr (0.5 wt% TiZr/PES), TiZn (0.5 wt% TiZn/PES), SPEEK/TiZr, and SPEEK/TiZn.…”

In this study, an attempt was made to pretreat seawater using polyethersulfone (PES) mixed matrix membranes (MMMs) incorporated with titania-based binary metal oxides. Two different titania-based binary metal oxides were prepared, namely titania-zirconia (TiZr) and titania-zinc oxide (TiZn). The influence of hydrophilic and negatively charged sulfonated poly(ether ether ketone) (SPEEK) polymer as additive of PES MMMs was also studied. Morphological and elemental analysis revealed that both ZrO 2 and ZnO were well dispersed in the as-prepared binary metal oxide TiZr and TiZn, respectively.. Thermogravimetry analysis indicated the good compatibility of TiZr and TiZn with the SPEEK/PES polymer. The binary metal oxide incorporated SPEEK/ PES MMMs exhibited improved hydrophilic properties with a low water contact angle of 57 ± (0.6). SPEEK/PES MMMs incorporated with 0.5 wt% TiZr exhibited the highest permeability of 3.11 × 10 −7 ± (0.2) m/sÁkPa. Seawater pretreatment performance of membranes evaluated using natural organic matters containing high salinity feed water. TiZr and TiZn incorporated SPEEK/ PES MMMs exhibited 95% rejection for humic acid. SPEEK/PES MMMs loaded with 0.5 wt% TiZr also showed the highest water flux and 87% water recovery within 90 min of seawater filtration. Both PES/SPEEK/TiZr and PES/SPEEK/ TiZn MMMs exhibited superior antibacterial activity.

“…The cross-sectional morphology of the membrane with two opposing skin layers is significantly different from the typical asymmetric structure of dry−wet spun PSf-based membranes. 25,26 As shown in Figure 1a, the AC particles distributed in the porous matrix and no particle clusters were observed. To obtain DLHF membranes, another dope solution containing the optimized composition of PSf and PMMA was co-extruded on top of the first layer.…”

The development of wearable artificial kidney demands an efficient dialysate recovery, which relies upon the adsorption process. This study proposes a solution to solve the problem of competitive adsorption between the uremic toxins by employing two adsorptive components in a membrane separation process. Dual-layer hollow fiber (DLHF) membranes, which are composed of a polysulfone (PSf)/activated carbon (AC) inner layer and a PSf/poly(methyl methacrylate) (PMMA) outer layer, were prepared for co-adsorptive removal of creatinine and urea from aqueous solution. The DLHF membranes were characterized in terms of morphological, physicochemical, water transport, and creatinine adsorption properties. The membrane was then subjected to an ultrafiltration adsorption study for performance evaluation. The incorporation of AC in membrane, as confirmed by microscopic and surface analyses, has improved the pure water flux up to 25.2 L/(m 2 h). A membrane with optimum AC loading (9 wt %) demonstrated the highest maximum creatinine adsorption capacity (86.2 mg/g) based on the Langmuir adsorption isotherm model. In the ultrafiltration adsorption experiment, the membrane removed creatinine and urea with a combined average percent removal of 29.3%. Moreover, the membrane exhibited creatinine and urea uptake recoveries of 98.8 and 81.2%, respectively. The combined action of PMMA and AC in the PSf DLHF membrane has made the adsorption of multiple uremic toxins possible during dialysate recovery.
