METHOD AND APPARATUS FOR DESALTING WHEY
Document Type and Number:
Japanese Patent JPS542371
Kind Code:
A
Abstract:
A method for desalination of whey which is conducted through an anion exchanger and a cation exchanger. The whey is first conducted through a weakly basic anion exchanger in hydrogen carbonate form and then through a weakly acidic cation exchanger in ammonium form. The ion exchangers are regenerated by treatment with an ammonium hydrogen carbonate solution, whereupon the ammonium and hydrogen carbonate ions present in the whey are removed by evaporation.
