Thoughts on the use of reverse osmosis for concentrating milk- and whey products, and the use of ultrafiltration to extract proteins from whey

Holland, S.

Meieriposten 75(26): 65-70


This discussion was presented at a Norsk Meieriteknisk Forening conference held on 8-9 April 1986. It gives a comparison of energy costs, for concentration of milk prior to drying, between reverse osmosis (RO), mechanical vapour recompression (MVR) and thermal vapour recompression (TVR) evaporation. RO is more economical than MVR or TVR for use in concentrating whey, milk of borderline quality for return to farms for animal feed, or increasing TS of milk for cheese or yoghurt making.
