Abstract
Methods and systems are provided for the efficient purification of aqueous liquids comprising an ionic solute. The liquids are purified by a plurality supercapacitor desalination units working in tandem; a first unit operating in 'charge' mode, deionizing the feed solution and producing a purified product liquid, while a second supercapacitor desalination unit is operated in 'discharge' mode, releasing ions into a circulating stream and producing a concentrate. The output of the first desalination unit is removed as a purified product stream. The output of the second desalination unit is a concentrate, which is directed to a common precipitation unit where a portion of the ionic solute is precipitated and separated from the remaining liquid phase, which may be recirculated to the second desalination unit. The use of two supercapacitor desalination units operating out of phase allows the common precipitation unit to be operated continuously under steady state conditions.
