Zusammenfassung: | Managing fouling from organic and biological materials has consistently posed a significant challenge in water and wastewater treatment via membrane technology. This research aimed to develop a new membrane with hydrophilic characteristics and assess its resistance to fouling. Hollow fiber membranes were created from PVDF polymer, enhanced with zeolite-Fe2O3 nanoparticle additives, using glutaraldehyde-H2SO4 cross-linking to incorporate hydrophilic elements. These modified membranes demonstrated notable surface porosity and improved hydrophilicity, with a reduced water droplet contact angle of 40° ± 0.6. The increased porosity led to a pure water flux of 141 L/m2h, a recovery rate (FRR) of 97 %, and rejection rates above 93 %.
