ABSTRACT:
A plurality of vortex cells are established in a tank of sea water. Each vortex cell is an individual unit with little mixing with adjacent cells. Cationic and anionic resins are introduced into an initial vortex cell. The resins are diffused through serially adjacent vortex cells and withdrawn from a final vortex cell. Sea water is added to the final vortex cell and purified water is withdrawn from the initial vortex cell, thus counter-flowing the resins and sea water. Water is transferred between cells by pumping. The exhausted resins are rejuvenated using a similar system. The materials removed during the rejuvenation are valuable by-products.
