ABSTRACT:
Treatment of water solutions by means of ion exchange; the exchange mass through which the liquid under treatment flows is conducted from a bottom funnel of the treatment container to a regenerating-and-wash-column and then back to the liquid treatment container. After leaving the liquid treatment container and before entering the regenerating-and-wash-column the ion exchange masses are back-rinsed in a back-rinse container; the ion exchange mass is transported from the regenerating-and-wash-column by means of an immersion tube at the top of the regenerating-and-wash-column, the depth of immersion of the immersion tube being adjustable according to the volume in the bottom funnel of the treatment container; consequently the ion exchange mass in the head of the regenerating-and-wash-column which has been transported from the treatment container corresponds to the volume transported from the bottom funnel thereof.
