PERFORATED GRAPHENE DEIONIZATION OR DESALINATION

摘要

A fluid deionizer includes at least one graphene sheet perforated with apertures dimensioned to allow a flow of fluid and to disallow at least one particular type of ion contained in the flow of fluid. A purge valve is placed in an open position so as to collect the at least one particular type of ion disallowed by the graphene sheet so as to clean off the at least one graphene sheet. Another embodiment provides a deionizer with graphene sheets in cylindrical form. A separation apparatus is also provided in a cross-flow arrangement where a pressurized source directs a medium along a path substantially parallel to at least one sheet of graphene from an inlet to an outlet. The medium flows through the plural perforated apertures while a remaining portion of the medium and the disallowed components in the medium flow out the outlet.

主权项

1. A method for deionizing fluid carrying unwanted ions, said method comprising:
providing at least one sheet of graphene with plural perforated apertures selected to allow the passage of fluid and to disallow the passage of at least one selected one of said unwanted ions; forming said at least one sheet of graphene into a cylindrical form; inserting said cylindrical form into a housing; pressurizing said fluid carrying unwanted ions to thereby generate pressurized fluid to flow through said housing; applying said pressurized fluid to a first surface of said at least one perforated graphene in said cylindrical form, so that fluid flows to a second side of said at least one perforated graphene sheet in cylindrical form in preference to ions; and collecting said fluid from said second side of said at least one graphene sheet.
