Abstract
PURPOSE:To remove Mg and Ca from saline water, in high efficiency, by passing a saline water obtained by dissolving raw salt and adjusted to specific conditions, through a packed layer composed of a chelate-forming water-insoluble resin having N-CH2COOH group and capable of forming intramolecular complex with Mg and Ca. CONSTITUTION:A column is packed with a chelate-forming water-insoluble resin capable of forming intramolecular complex with Mg and Ca, having N- CH2COOH group, and selected from styrene-butadiene copolymer, epichlorohydrin polymer, N-phenyl-glycine-glycidyl methacrylate copolymer, and styrene- divinylbenzene copolymer. The saline water obtained by dissolving raw salt and adjusted to 3-10pH is passed through the column at a space velocity of <=20hr<-1>.
