Abstract
The invention relates to a process for softening an aqueous sugar juice containing sugars and Ca.sup.2+ and/or Mg.sup.2+ ions, such as a sugar factory molasses by means of a cation exchange resin, in the form of Na.sup.+ and/or K.sup.+, and for regeneration of said resin, comprising: (a) a softening step wherein the said sugar juice is brought into contact with the said cation exchange resin, in the form Na.sup.+ and/or K.sup.+, to give, on the one hand, a softened sugar juice depleted in Ca.sup.2+ and/or Mg.sup.2+ ions and charged with Na.sup.+ and/or K.sup.+ ions and, on the other hand, a cation exchange resin charged with Ca.sup.2+ and/or Mg.sup.2+ ions, and (b) a step for the regeneration of said latter resin, characterised in that the regeneration step (b) comprises bringing the said resin into contact with a liquid effluent produced on separation by chromatography of the sugars from a softened aqueous sugar juice containing sugars and Na.sup.+ and/or K.sup.+ ions, said liquid effluent containing the majority of the Na.sup.+ and/or K.sup.+ ions initially present in the softened sugar juice.
