摘要

Polyethersulfone (PES) with polyvinyl chloride (PVC) and polyvinylpyrrolidone were prepared by blending through a non-induced phase inversion method. PES/PVC ultrafiltration membranes with different proportions of polymers were prepared and characterized. The study aims to explore the PES composite membranes for application in industrial wastewater treatment. The morphology was confirmed for prepared membranes with scanning electron microscopy (SEM), and the membrane’s hydrophilic properties were observed using the porosity measurement, contact angle, and swelling ratio of the prepared membranes. The thermal stability of the prepared membranes was confirmed by DSC and TGA. Dead-end filtration experiments were used to optimize the prepared polymer blend membranes. From the results, it was found that the mechanical strength was enhanced by the addition of PVC. The prepared membranes have been successfully explored in the membrane bioreactor (MBR) containing industrial wastewater for chemical oxygen demand (COD) and complete removal of total suspended solids (TSS).
