A method for purifying water, comprising separating a supply stream into a permeate stream and a reject stream, removing non-monovalent salt impurities from the reject stream to produce a treated stream; providing the treated stream to a concentrating compartment of an electrodeionization unit; and, producing an EDI product stream of purified water. The common electrode encircles the pixel area for shielding the electric field from the black matrix, thereby preventing a stray electric field from entering the pixel area and degrading the image quality. The second ink jet comprises at least one crosslinkable polymer or is otherwise energy curable. The facilitated transport membrane for olefinparaffin separation of the present invention comprises a polymer, a silver salt, and a phthalate compound represented by the following formula 1wherein R denotes an alkyl group of 2 to 8 carbon atoms or a phenyl group. A controller is operative to receive the flow signal and control the valves such that selected inputs of specific liquid fuels are dispensed to at least one of the fuel hoses.
