This paper introduces the results of experimental investigations on the influence of operating parameters, such as feed flow rate, temperature, pressure difference in the microfiltration through the ceramic Kerasep membrane. The results confirmed earlier work on the same laboratory device for microfiltration. and they are the main condition for determination of kinetics juice clarification. Apart from investigations on the influence of operating parameters, the influence of membrane moisture on microfiltration was observed.

Application of ultrafiltration to apple juice clarification

Faculty of Agriculture, Belgrade-Zemun (1,2,3,4)


Raw depectinized apple juice was clarified in a laboratory scale ultrafiltration (UF) system using ceramic tubular membranes (Tech-Sep Carbosep) with a molecular weight cut-off of 300,000, 50,000, and 30,000 daltons. The experiments have been carried out over a wide range of transmembrane pressures (100-400 kPa), temperatures (293-328 K), and feed flow rates (100-900 mL/min). Permeate flux significantly decreased with time until a steady state was established.
