System, method, and control for graphenoid desalination

摘要

A method is disclosed for deionizing water and purging ions. A first graphene sheet and a second graphene sheet are positioned between a water flow path input and output. A first electrical charge is applied to the first graphene sheet and a second electrical charge to the second graphene sheet, which causes the first graphene sheet to repel ions of the first electrical charge from transiting apertures in the first graphene sheet, influences ions of the second electrical charge from transiting the apertures in the first graphene sheet, and causes the second graphene sheet to repel ions of the second electrical charge from transiting the second apertures. Water is introduced into the water flow path input, through the first graphene sheet, and then through the second graphene sheet, resulting in deionized water at the output. A sensor monitors the capacitance of the graphene sheets to determine when purging is needed.

1. A method for deionizing water carrying ions, said method comprising the steps of:
providing a first graphene sheet with first apertures dimensioned to allow flow of water molecules; providing a second graphene sheet with second apertures dimensioned to allow flow of water molecules; positioning the first graphene sheet downstream to a water flow path input and positioning the second graphene sheet between the first graphene sheet and a water flow path output; applying a first electrical charge to the first graphene sheet and a second electrical charge to the second graphene sheet, thereby causing the first graphene sheet to repel first ions of the first electrical charge from transiting the first apertures, the repelled first ions influencing second ions of the second electrical charge to not transit the first apertures, and causing the second graphene sheet to repel second ions from transiting the second apertures, the repelled second ions influencing the first ions to not transit the second apertures; causing water to enter the water flow path input, through said first graphene sheet and then through said second graphene sheet, thereby resulting in the first ions and the second ions accumulating between the water flow path input and the first graphene sheet, second ions accumulating between the first graphene sheet and the second graphene sheet, and deionized water at the water flow path output; monitoring an ion density of the first graphene sheet and the second graphene sheet; and when the ion density exceeds a threshold level, purging the first ions and the second ions.
