Methods and apparatuses for filtering water fluid by screening ionic minerals

A water-filtering apparatus, comprising:

• a water processing station configured and arranged to process water fluid having ionic minerals therein including sodium chloride, in 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;
• an anode reservoir station;
• a cathode reservoir station;
• a power source configured and arranged to apply respective electric voltages, while the water fluid is 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 and
• the 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
• a water collection station configured and arranged to receive the ion-filtered water from the work zone.
