Filtration rate and resistance are affected by the operations prior to filtration in fruit juice production lines. In this research, the effects of depectinization and clarification on filtration resistance and rate were evaluated. Filtration studies on raw juice, depectinized juice and depectinized plus clarified juice were compared. It was observed that pretreatments reduce the resistance considerably. In addition, the effects of the amount of precoating and the filter medium type on filtration rate were also studied. Decreasing the amount of precoating increased the filtration rate. Fabric filter medium had a lower resistance than commercial asbestos filter pads. © 1993.
