Abstract
Various aspects of the present disclosure are directed toward apparatus and methods method for filtering water fluid by screening ionic minerals including sodium chloride from the water fluid. In one embodiment, the water fluid is passed into a work zone defined at least in part by oppositely-arranged first and second porous structures, each of which have a plurality of gated channels. The water fluid is processed in the work zone by applying respective electric voltages to electrically bias the first porous structure and the second porous structure. The respective electric voltages deplete sodium chloride ions in the water fluid in the work zone due to ion-flux continuity. In response to processing of the water fluid, ion-filtered water is collected from the work zone.
