Abstract
Novel Polyetherimide (PEI) composite membrane has been investigated to improve the mechanical and antifouling properties. In this study, the preparation and properties of polyetherimide ultrafiltration polymer membranes with pectin as blending additive and tungsten oxide as anti-bacterial agent was studied. The membrane characteristic and performance were investigated by membrane morphology, hydrophilicity, atomic force microscopy, water uptake, zeta potential, pure water flux and antifouling behaviour using model pollutants such as bovine serum albumin, humic acid and real textile wastewater (MBR permeate). It was clearly seen that the biofouling properties were greatly enhanced due to the addition of metal oxide.
