NOVELTY - Deionizing fluid carrying unwanted ions involves providing at least one sheet of graphene (212) with perforated apertures selected to allow the passage of fluid and to disallow the passage of one of the unwanted ions; forming the sheet of graphene in the cylindrical form into a housing; applying the pressurized fluid to a first surface of the perforated graphene in the cylindrical form, so that fluid flows to a second side of the perforated graphene sheet in cylindrical form in preference to ions; and collecting the fluid from the second side of the graphene sheet. USE - For deionizing fluid carrying unwanted ions selected from chlorine, sodium (claimed). ADVANTAGE - The method provides much improved filtering with much lower required energy per incremental salt removal step. DETAILED DESCRIPTION - Deionizing fluid carrying unwanted ions involves providing at least one sheet of graphene (212) with perforated apertures selected to allow the passage of fluid and to disallow the passage of at least one selected one of the unwanted ions; forming the sheet of graphene into a cylindrical form; inserting the cylindrical form into a housing; pressurizing the fluid carrying unwanted ions to generate pressurized fluid to flow through the housing; applying the pressurized fluid to a first surface of the perforated graphene in the cylindrical form, so that fluid flows to a second side of the perforated graphene sheet in cylindrical form in preference to ions; and collecting the fluid from the second side of the graphene sheet. INDEPENDENT CLAIMS are included for the following: (1) a fluid deionizer comprising a cylindrical form of at least one graphene sheet perforated with apertures dimensioned to allow the flow of fluid and to disallow the flow of ions of at least one particular type; a source of fluid laden with ions of the particular type; and a path for the flow of the fluid laden with ions of the particular type through the cylindrical form of at least one graphene sheet perforated with apertures; (2) separating components from a medium, involving providing a primary sheet of at least one layer of graphene with perforated apertures selected to allow the passage of a medium and to disallow the passage of selected components in the medium; providing the primary sheet of at least one layer of graphene in a primary chamber, where the primary chamber having a primary inlet, a primary outlet, and a primary lower flow path; and pressurizing the medium to flow in a path substantially parallel to the primary sheet of at least one layer of graphene from the primary inlet to the primary outlet, the medium flowing on to a first surface of the primary sheet of at least one layer of graphene so that a portion of the medium flows to a second side of the primary sheet of at least one layer of graphene through the perforated apertures while a remaining portion of the medium and the disallowed selected components in the medium flow out the primary outlet; (3) a separation apparatus comprising at least one chamber having an inlet, an outlet and a lower flow path; at least one sheet of graphene perforated with apertures dimensioned to allow passage of a medium and to disallow passage of selected components in the medium, where the graphene positioned in the chamber; and a pressurized source of the medium connected to the chamber having the inlet, where the pressurized source directing the medium along a path parallel to the sheet of graphene from the inlet to the outlet, the medium flowing on to a first surface of the sheet of graphene so that a portion of the medium flows to a second side of the graphene sheet through the plural perforated apertures while a remaining portion of the medium and the disallowed selected components in the medium flow out the outlet.
