  • Systems and methods for flow-through treatment of contaminated fluids
    Patent number: 7727306
    Abstract: A system for use in the treatment of contaminated fluid is provided. The system includes a source from which contaminated fluid may be introduced into the system, and a reservoir for an adsorbent material designed to remove contaminants from the fluid. The system also includes a reactor within which the adsorbent material and the contaminated fluid may be accommodated for treatment. A separation device may further be included for removing spent adsorbent materials from the system. A method for treating contaminated fluid is also provided.
    Type: Grant

  • Systems and methods for removal of heavy metal contaminants from fluids
    Publication number: 20090032472
    Abstract: A system for use in the removal of heavy metal contaminants from fluid is provided. The system includes a source from which contaminated fluid may be introduced into the system, a first station for removal by physical separation of a targeted heavy metal contaminant from the flow of fluid, including elemental species of the targeted heavy metal contaminant, and a second station positioned downstream of the first station and in fluid communication therewith for adsorptive separation of the targeted heavy metal contaminant from the fluid flow, including additional amount of the elemental species along with the other species of the targeted heavy metal contaminant. A method for removing heavy metal contaminants from fluid is also provided.
