Abstract

La présente invention concerne la purification des solutions salines. Ce procédé consiste à déminéraliser une solution saline contenant des ions bicarbonate ou bisulfite en utilisant des résines échangeuses d'ions amphotères régénérables par la chaleur, la régénération desdites résines s'effectuant en utilisant, comme agent de régénération, une solution qui est plus acide que la solution saline. L'invention est par conséquent utile pour déminéraliser les solutions salines.
