Concentration

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

Ultrafiltration has been investigated for the concentration of diluted biopolymer solutions. Trials were realized with membranes of different molecular weight cut off (MWCO) and configuration modules. Results indicates that hollow fiber module gives the best results with the membrane of 6 kilodalton

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

Ultrafiltration (UF) of gelatin liquor from marine source (tuna skins) has been performed on a tubular mineral membrane of cut-off 10,000 Da. An attempt was made to concentrate the fish gelatin as well as to purify it by means of the diafiltration technique (DF). Primary experiments were devoted to

Bovine blood is a potentially important source of raw material for the alimentary industry and many pharmacochemical industrial products. Different fractions obtained with the application of membrane separative techniques were studied, orientating our work to obtain bovine seroalbumin (BSA). Pretrea
