Abstract: Two experimental methods have been developed to characterize the pressure-driven flow of a liquid through the walls of single hollow-fiber membranes. In one method, the permeation rate is measured directly by following the air-water interface in a pressurized pipet connected to a hollow fiber which is sealed at one end. With the second method, the permeation rate is determined by tracking the decent of an air bubble inside a pressurized hollow fiber sealed at one end. Results obtained by the two experimental m…
