In this research, at first hollow fiber membranes with different structures and polymer kinds will be prepared. Several kinds of polymers will be used for membrane preparation, and for each kind of the polymer, membranes with different structure will be prepared by changing the hollow fiber membrane spinning conditions. Prepared membrane will be characterized with special focus on the fouling behavior. Considering the trend of the results for different prepared membranes with different structures and polymer kinds, potentially can clarify the effect of membrane structure on the fouling tendency.
