  • Compositions to remove radioactive isotopes and heavy metals from wastewater
    Patent number: 6855665
    Abstract: The present invention provides compositions and a method to remove a plurality of radioactive isotopes and/or heavy metals simultaneously from water or wastewater. The compositions comprise lattice clays; flocculants; a neutron absorbent; catalysts; and a setter. The selected compositions is entered into a vessel and agitated with the water to produce a sludge containing the contaminants.

  • Compositions to remove heavy metals and radioactive isotopes from wastewater
    Patent number: 5880060
    Abstract: Treatment compositions and a method are provided for the removal of a plurality of heavy metals and radioactive isotopes from wastewater. The treatment compositions comprise an alkali; adsorbents, such as montmorillonite and illite clays; catalysts, such as polyelectrolytes and sodium carbonate; one or more flocculants, such as a metal salt and calcium hydroxide; zirconium as a chelating and complexing agent; and boron as a neutron absorbent. The selected composition is introduced into and mixed with the wastewater, which is then filtered to produce a sludge containing the contaminants.
