Evaluation of a Nanohybrid Membrane (PSF/ZnO) Efficiency in Natural Organic Matter Removal From Water

Background: Natural organic matter (NOM) in drinking water sources has always been regarded as a precursor for the formation of trihalomethanes (THMs), haloacetic acids (HAAs), and carcinogenic properties. This study aimed to fabricate characterize nanohybrid ultrafiltration membrane (PSF/ZnO) evaluate its efficiency NOM removal from water. Methods: Nanohybrid membranes with ratios 0, 1, 2, 3 4% w/w ZnO nanoparticles (NPs) were fabricated using phase inversion method characterized by contact angle, AFM, FTIR, SEM analyses. In this study, effects initial humic acid (HA) concentration, operating pressure, pH, filtration time examined on HA pure flux through membrane. Results: The results showed that addition NPs PSF reduced angle PSF/ZnO membrane’s surface. According FE-SEM images, increasing concentration changed porous structure spongy, teardrop shape finger-like channel structure. FTIR analysis revealed an increase hydrophilicity due presence hydroxyl functional groups ZnO. AFM images indicated surface roughness nanoparticle-containing membranes. It was found (0-4% w/w) increased (43.63-83.4%). Conclusion: demonstrated use passing
