Decalcification method of an aqueous solution, in particular whey or a permeate ultrafiltration whey.

摘要

Procedure descaling of an aqueous solution comprising multivalent cations Cae + and Mg2 + and anions able to form complexes with at least part of the polyvalent cations, characterized in that it comprises the operations: (a) replacement of a part at less than said anions to form complexes capable of not able to form such complexes aqueous solution by monovalent anions such as Cl-, and (b) of replacement of at least a part of said multivalent cations of the aqueous solution for a monovalent such as Na + and / or K +, wherein the step (b) conducted simultaneously with step (a) or performed on the aqueous solution to undergone operation (a) metal cations.
