▎ 摘 要
NOVELTY - Method (M1) for deionizing fluid carrying unwanted ions, involves (a) providing at least one sheet of graphene with plural perforated apertures, (b) forming at least one sheet of graphene into a cylindrical form, (c) inserting cylindrical form into a housing, (d) pressurizing fluid carrying unwanted ions, (e) applying pressurized fluid to a first surface of at least one perforated graphene in cylindrical form, to second side of at least one perforated graphene sheet in cylindrical form in preference to ions, and (f) collecting fluid from second side of at least one graphene sheet. USE - The method (M1) is useful for deionizing fluid carrying unwanted ions. The method (M2) is useful for separating components from a medium (all claimed). ADVANTAGE - The method enables to deionize fluid carrying unwanted ions in a energy saving manner, as the pressurized flow of the medium in a direction is parallel with the membrane, and requires much lower required energy per incremental salt removal step. DETAILED DESCRIPTION - Method (M1) for deionizing fluid carrying unwanted ions, involves (a) providing at least one sheet of graphene with several perforated apertures chosen to allow the passage of fluid and to disallow the passage of at least one of unwanted ions, (b) forming at least one sheet of graphene into a cylindrical form, (c) inserting cylindrical form into a housing, (d) pressurizing fluid carrying unwanted ions to generate pressurized fluid to flow through housing, (e) applying pressurized fluid to a first surface of at least one perforated graphene in cylindrical form, to second side of at least one perforated graphene sheet in cylindrical form in preference to ions, and (f) collecting fluid from second side of at least one graphene sheet. INDEPENDENT CLAIMS are included for the following: (1) fluid deionizer; (2) method (M2) for separating components from a medium; and (3) separation apparatus.
