Using foil membranes for demineralization of whey by electrodialysis

AbstractThe aim of the experiments was to verify the possibility of using film ion-exchange membranes for demineralization of whey by electrodialysis (ED). Foil and standard ion-exchange membranes behaved similarly in process of ED of whey, capacity of ED with foil membranes was only slightly higher by 3–5%. Advantage of foil membrane usage lies mainly in their lower production costs.
