Comparison of L-lysine Ultrafiltration Kinetics between Hollow-fiber Membrane and Plate Membrane

The ultrafiltration kinetics of L-lysine is studied in the hollow-fiber membrane and the plate membrane respectively. As a result, the filtration fluxes of hollow-fiber membrane are far larger than those of plate membrane. Compared with that of the plate membrane, the ultrafiltration kinetics of the hollow-fiber membrane is more in accord with concentration polarization-gel layer model into which the ultrafiltration kinetics of L-lysine is fitted.
