Abstract
An apparatus for reducing the total dissolved solids of a solution includes a unit having at least two chambers; a respective semi-permeable membrane arrangement disposed between each of the at least two chambers; a device for introducing respective solutions into, and withdrawing solutions from, the chambers; and at least one paddle disposed in each of said chambers. The paddles are configured to sweep opposite sides of each of the semi-permeable membrane arrangements. A device provides relative movement between the paddles and the semi-permeable arrangements.
