Fouling resistant ultrafiltration membranes based on the blends of PES/PVA/SiO2 from rice husk were prepared by using phase inversion process. The influences of PVA and SiO2 on the preparation of phase inverted PES ultrafiltration membrane were explored in terms of morphology study, equilibrium water content, hydrophilicity, and thermal stability. After the introduction of PVA and SiO2 to the ternary (polymer-solvent-non-solvent) system, the formations of finger-like structures and macro-voids were reduced significantly. An improvement in porosity, average pore size, and hydrophilic nature of the PES membranes were detected after the introduction of PVA and SiO2 into the polymer matrix. The interaction between SiO2 and PES was confirmed and the degradation temperature of the PES membrane was significantly improved. Bovine serum albumin (BSA) protein removal efficiency, anti-fouling performance, and recycling potential of the UF membranes were investigated. The PES/PVA/SiO2 membrane has displayed high BSA removal efficiency and flux recovery ratios with enhanced anti-fouling performances for the three fouling/rinsing cycles. © 2025 Author(s).
