Optimum Design for Ultrafiltrator of Hollow Fiber Membrane

摘要

Ultrafiltration is one of the separating technology by membrane which has been used and studied widely. When hollow fiber membrane is ultrafiltrating, driving force and filtrate rate decrease with the length of hollow fiber because of flow resitance, but the flow resistance is related to inernal diameter of hollow fiber. In this paper, we have established the mathematical model of ultrafiltration and obtained the optimum relationship between the internal diameter and length in order to acheive maxiumum filtrate amount in a unit of volume and pressure difference.
