Ultrafiltration of sugarcane juice with spiral wound modules: on-site pilot trials

摘要

This work investigate the performance of spiral wound membrane modules for the ultrafiltration (UF) of sugarcane juice. In on-site trials carriout in an Indian sugar mill, different modules with varying channel sizes employing 20 kDa polyethersulphone and polysulphone membranes were evaluated. Two juice streams viz. raw juice and clarified juice were selected in the sugar manufacturing process and the effect of such operating parameters as transmembrane pressures, operating time and feed temperature on the permeate flux and quality were examined.
