High flux polysulfone braided hollow fiber membrane for wastewater treatment role of zinc oxide as hydrophilic enhancer

Incorporation of zinc oxide (ZnO) nanoparticles has played an important role on the improvement unique membrane characterization and performance, most notably hydrophilic modification for higher pure water permeability. Additionally, permeability can be improved via introduction braid support by reducing thickness separation layer. Moreover, braided hollow fiber (BHFM) is able to perform under pressure conditions compared membranes. In this paper, hybrid polysulfone (PSf)/ZnO BHFMs were fabricated phase inversion method. Hydrophilic 10 ± 1.8 nm polycrystalline ZnO synthesized sol-gel method incorporated BHFM improve hydrophilicity increase flux with constant rejection high effect loading properties performance thoroughly studied. The 0.0, 0.5, 1.0 1.5 wt% concentration defined as BHFM1, BHFM2, BHFM3 BHFM4 respectively. Scanning electron microscopy (SEM), contact angle, mechanical strength, bovine serum albumin (BSA) fouling best performed conducted achieve target paper. these ZnO/PSf neat PSf (HFM) previous studies. findings from research work shows that desired wastewater treatment application. in have 108.79° 71.02°, thus increased 36.20 919.12 L/m2 h at bar 193.48 1909.11 L/m2h 4.0 when BHFM1.
