ABSTRACT

Predicting equations for the permeate flux of membrane ultrafiltration in a tubular module with a steel rod inserted concentrically were derived from momentum and mass balances with the application of the resistance-in-series model, coupled with the considerations of declinations of flow rate and transmembrane pressure along the membrane tube. Experimental work for the ultrafiltration of dextran T500 aqueous solution was carried out in such a modified tubular ceramic membrane module made of ZrO₂/CO₂. Correlation predictions are confirmed with the experimental results, especially for the practically operating range of transmembrane pressure.
