Abstract
Abstract The method and system for removing ions from an ionized liquid includes electrically charging the ions, establishing a given flow direction, and applying a magnetic field to the electrically-charged ions causing movement of the ions in the direction of fluid flow. Liquid having higher ion concentration is discharged at a location remote in the direction of flow, and liquid having lower ion concentration is withdrawn near the location of the applied magnetic field.
