The potential of microfiltration and ultrafiltration process in purification of raw sugar beet juice

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.
