Abstract

A system for removing a dissolved substance from a solution comprises a channel (10) defining a flow path of the solution, a first set of electrodes (20) proximate an inner surface of the flow path, and a second set of electrodes (22) proximate an inner surface of the flow path. A solution including a plurality of positive ions and a plurality of negative ions is introduced into the channel (10). A first varying electric field is applied to the channel (10) via the first set of electrodes (20) and a second varying electric field is applied to the channel (10) via the second set of electrodes (22). The first and second fields cause at least one region of concentration of positive ions and at least one region of concentration of negative ions, the first and second regions being located such that at least a portion of the negative ions combine with at least a portion of the positive ions to create a crystal structure.
