Abstract
A water-deionizing system comprising a reservoir for receiving a quantity of water to be deionized, a first ion-exchanger unit capable of removing anions from said water, and a second ion-exchanger unit capable of removing cations from said water. The first and second ion-exchanger units are connected to said reservoir to form separate flow paths or circuits for circulating water from the reservoir through the units separately in parallel. The system permits efficient production of a relatively large amount of water in a batchwise operation and also facilitates the regeneration of saturated ion-exchangers.
