the simultaneous effect of different fluxes and enzymes in a membrane system containing cherry juice: membrane fouling assessment

Nowadays, diminishing fouling issue through membrane systems are one the biggest challenges in the industry. in this study, the simultaneous effect of two fluxes 8.62 and 17.24 l m-2 h-1 and two enzymes pectinase and protease on the fouling subject in the designed membrane system were analyzed. the results depicted that when the flux values rose two-fold (from 8.62 to 17.24 l m-2 h-1) the ratios of cake hydraulic resistance (rc) to total hydraulic resistance (rt) were increased 31% and 10% for no-enzyme and with-enzyme streams, respectively. these rises were so severe in the ratios of pore-blockings (rc) to total resistances (rt) with almost 27% and 108% for 8.62 and 17.24 l m-2 h-1 fluxes, respectively. likewise, using enzymes caused a decrease in the rc/rt ratios for about 46% and 54%, respectively. however, applying these enzymes led to a 3.45-fold and 6.28-fold rise when the flux was raised from 8.62 and 17.24 l m-2 h-1.
