摘要
Ultrafiltration of calf serum and bovine serum albumin (BSA) in the pregel region has been studied in Cuprophan hollow-fiber filters of various lengths and number of fibers, and at several axial flow velocities. Graphs of ultrafiltration velocities versus transmembrane pressure show a surprising independence from fiber length and axial flow velocity. Results are correlated by osmotic-pressure data and an available boundary layer theory derived originally for uniform-wall-flux processes in the far-downstream (asymptotic) region.
