A method of generating a base comprising the steps of:
(a) providing a cation source in a cation source reservoir (10),
(b) flowing an aqueous liquid stream through a first base generation chamber (19) separated from said cation source reservoir by a first barrier (14) substantially preventing liquid flow while providing a cation transport bridge,
(c) applying an electric potential between an anode (16) in electrical communication with said cation source reservoir and a cathode (18) in electrical communication with said first base generation chamber to electrolytically generate hydroxide ions in said first base generation chamber and to cause cations in said cation source reservoir to electromigrate toward said first barrier and to be transported across said first barrier toward said cathode to combine with said hydroxide ions generated at the cathode to form cation hydroxide, and
(d) removing the cation hydroxide in an aqueous liquid stream (21) as an effluent from said first base generation chamber. |
