effect of processing parameters on the microfiltration fouling during the clarification of pomegranate juice
the pomegranate juice with high nutritional value has turbid appearance that makes it difficult to preserve and concentrate. microfiltration is useful process which can clarify it. one of the most important problems in this process is fouling phenomenon which affected by several parameters. the effects of fluid velocity, transmembrane pressure, membrane type and its pore size on membrane foulin...
متن کاملIntelligent Modeling of Permeate Flux during Membrane Clarification of Pomegranate Juice
Background and Objectives: One of the problems in juice membrane clarification is the accumulation and deposition of rejected compounds on membrane surfaces or inside its pores which results in a membrane fouling. Materials and Methods: Several parameters can have influence on fouling in one hand and prediction of juice permeates flux during the membrane processing is of importance in indust...
متن کاملDifference between efficiency of ultrasound treatments above and below the membrane surface in membrane clarification of pomegranate juice
Microfiltration can clarify pomegranate juice; however, fouling is a limiting phenomenon in the process. In current work ultrasound was applied above and below the membrane surface to reduce fouling after removing temperature effect. A hydrophilic mixed cellulose ester membrane with pore size of 0.45 μm was used in lab scale flat sheet module. Membrane module was placed above and below the ultr...

متن کاملSimulation of the Effect of Centrifugation on Membrane Efficiency by Using Computational Fluid Dynamics During the Clarification of Pomegranate Juice
Background and Objectives: Pomegranate juice is prone to turbidity, which makes it hard to preserve and concentrate. Microfiltration is one of the membrane processes that can be used to reduce its turbidity, but, it is prone to membrane fouling. Pretreatment is considered the most effective way to reduce membrane fouling. Materials and Methods: This study simulated the effect of centrifugation...
