In this paper, the effect of operation parameters of microfiltration (MF) and ultrafiltration (UF) processes on the performance of purification and de-colorization of raw juice have been studied. Experiments were carried out using the pilot plant MF/UF membrane system equipped to a tubular module with a ceramic membrane and spiral module with a polymeric membrane, respectively. The results showed that the clarified juice quality obtained from MF/UF method was improved greatly as compared to conventional limed-carbonated clarified juice in color, turbidity and hardness in the rate of 49.12%, 78.26% and 6.65%, respectively.
