ALUATION OF DIRECT CONTACT MEMBRANE DISTILLATION FOR CONCENTRATION OF ORANGE JUICE

In this work Membrane Distillation is applied to concentrate orange Juice. Clarified orange juice (11.5o Brix) obtained from fresh fruits was subjected to membrane distillation. The experiments were performed on a flat sheet module using orange juice as feeds. The concentration was carried out in a direct contact membrane distillation using hydrophobic PTFE membrane of pore size 0.2 μm and porosity 70%. The influences of the feed temperature, feed concentration, flow rate, operating time on the transmembrane flux were studied.
