ABSTRACT:
The process valorizes food by-products by a reverse osmosis. The pH is temporarily lowered by the injection of carbon dioxide in the medium containing the food by-product before its pre-concentration by reverse osmosis, preferably in the medium to be treated under low or moderate pressure, at a point at which the velocity of circulation of the liquid medium increases. System for introducing carbon dioxide between the low-moderate pressure pump 4 and the high pressure pump 8 at the entrance of the conical device 7. Application in the pre-concentration by reverse osmosis of food by-products, and in particular the lactoserum.
