✦ Synopsis

Predicting equations for the permeate flux of membrane ultrafiltration in a tubular module were derived from momentum balance with the considerations of declining flow rate and transmembrane pressure along the membrane tube. Correlation predictions are confirmed with the experimental results. The effects of solute concentration, transmembrane pressure, tube radius and tube length on the flux and pressure declines along the membrane tube were thoroughly discussed.

It was reported in previous works that the performance of ultrafiltration in tubular membranes could be improved by concentrically inserting a steel rod, and further improved by wrapping a wired spiral of uniform angles on the entire rod, to increase fluid velocity and thus, to decrease the concentr
