Abstract

Fabrication of an efficient microfiltration polymeric membrane with low fouling characteristics and high permeation flux is an essential task for conducting membrane-related research and its development toward its industrial applications. Surface skin layer which decreases the membrane permeation and accelerates the MEMBRANE FOULING in purification and separation of protein solution is usually observed for all membranes fabricated via thermally induced phase separation (TIPS) method. In this work, the impact of coagulation bath temperature on the skinlayer thickness and performance of fabricated membranes was investigated. Collagenprotein purification tests were carried out to investigate the impact of skin layer on the performance and fouling mechanisms of the membranes. The obtained results showed that when coagulation bath temperature increases, the thickness of skin layer decreases.In membranes with lower surface porosity, the decline in protein permeation is mainly due to the standard blocking fouling mechanism which is a kind of the irreversible fouling phenomenon. In membranes with higher surface porosity, however, decline inprotein permeation is mainly due to the intermediate blocking fouling mechanism which is a kind of reversible fouling phenomenon. The obtained results from permeation flux and spectrophotometric analyses of the inlet feed and retentate streams within 800 min showed that the collagen recovery ratio for modified membrane was 5.6% and that of an unmodified membrane was less than 1%. It is worth to mention that for membrane with lower surface porosity the collagen filtration process was stopped within 400 mindue to the MEMBRANE FOULING. For membrane with higher surface porosity, however there was no halting in filtration process within 800 min.
