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...

A novel configuration of pervaporation and vapor permeation processes is introduced. In the suggested process the driving force for permeation is enabled by the absorption of the permeate vapors using a suitable solvent with a low vapor pressure. Thus, the refrigeration needed for condensing the permeate under vacuum can be overcome and cost savings can be achieved. Moreover, very low vacuum pr...

Ultrafiltration is mainly used to concentrate macromolecules and removing salts and smaller molecules through the membrane. Sharp separation is rarely seen which is partly due to the coupling of solute and water transport and the concentration polarization at the membrane surface. In case of real fractionation of macromolecules a decoupling of the solute transport from the water transfer togeth...

The purpose of this work was to analyse the potentialities of an integrated membrane system for the recovery, purification and concentration of polyphenols from olive mill wastewater (OMW). The proposed system included some well-known membrane operations such as microfiltration (MF) and nanofiltration (NF), as well as others not yet investigated for this specific application, such as osmotic di...
