METHODS AND APPARATUSES FOR FILTERING WATER FLUID BY SCREENING IONIC MINERALS

摘要

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.

1. A method for filtering water fluid by screening ionic minerals including sodium chloride from the water fluid, the method comprising:
passing the water fluid into a work zone defined at least in part by oppositely-arranged first and second porous structures, the first porous structure having a plurality of gated channels corresponding to an anode reservoir and the second porous structure having a plurality of gated channels corresponding to a cathode reservoir; processing the water fluid in the work zone by,
applying respective electric voltages to electrically bias,
the first porous structure and the corresponding anode reservoir with a first bias-polarity type andthe second porous structure and the corresponding cathode reservoir with a second bias-polarity type that is opposite the first bias-polarity type,the respective electric voltages being set to establish a sufficient voltage difference therebetween to deplete sodium chloride ions in the water fluid in the work zone due to ion-flux continuity, whereby sodium chloride anions are passed from the work zone through the plurality of gated channels of the first porous structure to the anode reservoir, and sodium chloride cations are passed from the work zone through the plurality of gated channels of the second porous structure to the cathode reservoir; and collecting, in response to the step of processing, ion-filtered water from the work zone.
