The efficacy of sugarcane juice clarification was studied with a polysulphone hollow fibre ultrafiltration membrane module having molecular weight cut-off of 20,000. The fouling index, pH optimization and permeate sterility were evaluated at 1.2 kg/cm(2) transmembrane pressure using the same module. The turbidity value of ultrafiltered sugarcane juice was found to be 0.5 NTU as compared to 200-250 NTU in the raw sugarcane juice. The maximum flux with least fouling was observed when the UF was carried out with a juice prelimed to bring it to about pH of 7.5 and the permeate was found to be free from microbes.
