摘要

Membrane technology is a promising solution for industrial wastewater treatment, though membrane fouling remains a major limitation. In this study, PVDF membranes were fabricated by incorporating 3-glycidoxypropyltrimethoxysilane (GPTMS)-modified cellulose (C-GPTMS) derived from oil palm empty fruit bunches (OPEFB) to enhance hydrophilicity and reduce fouling. C-GPTMS was synthesized via reflux and introduced into PVDF membranes via phase inversion. The resulting membranes exhibited increased water flux and significantly improved dye rejection up to 90% for methylene blue (MB) and 80% for reactive yellow (RY). Antifouling performance was also enhanced, with flux recovery ratios (FRR) reaching 99% for MB and 85% for RY. After five filtration cycles, the membranes retained over 80% of their initial flux, demonstrating excellent reusability for dye removal in wastewater treatment.
