Publication number: 20130134098Abstract: Methods for treating water to remove radium include contacting the water with a magnetic adsorbent comprising manganese oxide(s), and applying a magnetic field to separate the magnetic adsorbent from the water, whereby radium is removed from the water. The methods may additionally include regenerating the magnetic adsorbent, and contacting the water with regenerated magnetic adsorbent. Alternately, calcium and/or strontium may be precipitated as carbonate salts from lime-treated water containing radium and barium without precipitating a significant fraction of the barium or radium; and removing radium from calcium- and strontium-free water by precipitating the barium and radium as carbonate salts. The barium- and radium carbonate precipitate may be redissolved in hydrochloric acid and disposed of by deep-well injection.Type: ApplicationFiled: November 30, 2011Publication date: May 30, 2013Applicant: GENERAL ELECTRIC COMPANYInventors: William Leonard Kostedt, IV, James Manio Silva, Hope Matis, Vicki Herzl Watkins, Harish Radhakrishna Acharya

Patent number: 8333887Abstract: 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.Type: GrantFiled: October 23, 2008Date of Patent: December 18, 2012Assignee: General Electric CompanyInventor: James Manio Silva
