Abstract

Controlling the membrane structure and membrane performance is the most important goals in membrane technology application. Various parameters can be manipulated to carry out the tedious and sensitive process of membrane fabrication. This study aimed to investigate the effect of polymer concentration on the morphology and performance of asymmetric ultrafiltration (UF) membrane for Bovine Serum Albumin (BSA) separation. Flat sheet asymmetric UF membranes were fabricated via dry/wet phase inversion technique. These fabricated membranes were characterized in term of membrane morphology, membrane pore radius and membrane surface charge. The membrane performance was determined based on pure water flux, sodium chloride rejection and BSA permeation test. Promising results were obtained when BSA rejection was ranged from 94.3% to 100%. The optimum membrane this purpose of study was determined by PSF 17% (contained 17 wt% polymer concentration) which successfully exhibited 100% rejection together with high filtrate flux for about 30.57 L/m2.h at pressure 2 bars. Overall results verified that increased the polymer concentration would improve the membrane selectivity due to the smaller pore radius which able to maximize the BSA rejection. This research was also proved that polymer concentration would greatly affect the membrane performance and structural properties, consecutively enhancing the membranes ability for BSA separation.
