Membranebased separation processes are new technology combining membrane with conventional separation. The hollowfiber module has been widely used, since it has a larger ~ratio of surface area to volume,larger flux, and flow rate without limit. This article summarizes the present status of research on mass transfer characteristics, influence factors and mathematical model for the membranebased separation processes and discusses the research in the future.
