level. The objective of this experiment is to study the characteristic of four different types of membrane. The membranes used in this experiment are polyamide film ( AFC 99 ) as membrane one ‚ polyamide film ( AFC 40 ) as membrane two ‚ cellulose acetate (CA 202 ) as the third membrane and PVDF (FP 100 ) that act as the fourth membrane. In order to identify the characteristic of all four membranes‚ experimental procedures should be done. The variable for this experiment is the membrane maximum inlet
