Hydrophobic membranes

Vacuum Membrane Distillation is studied for the concentration of fruit juices up to 50°Brix. The fluxes of water and of the relevant aroma compounds are experimentally examined for a typical must, as a function of temperature, sugar content and downstream pressure. The process leads to juice concent

This paper presents an experimental procedure to analyse the heat and mass transfer phenomena involved in osmotic membrane distillation and to measure the related parameters. Use is made of a module containing a few membrane sheets in co-current flow configuration. Whatever the inlet feed and extrac
