  • Light weight medium for growing microorganisms
    Patent number: 6936446
    Abstract: A light weight medium for growing microorganisms includes a mass of polymeric foam, such as a polyurethane foam, having an outer region enclosing an inner region. A plurality of fragments of an inorganic material, such as sand, are at least partially embedded in the outer region. The light weight medium may be used to support growth of microorganisms in a wide variety of biological and/or biochemical processes, or may be used without microorganisms in chemically treating wastes.
    Type: Grant
    Filed: June 19, 2002
    Date of Patent: August 30, 2005
    Assignee: Eliminite, Inc.

  • Apparatus and method for modifying waste water
    Patent number: 5676828
    Abstract: An apparatus and method for modifying waste water to reduce nitrate content and biochemical oxygen demand is provided. The apparatus includes an ammonification and denitrification region having a substantially anaerobic environment, a nitrification region having a substantially aerobic environment, and an effluent drainage region. Effluent circulates through the ammonification and denitrification region and the nitrification region to convert organic nitrogen-containing compounds in waste water to nitrogen gas and carbon dioxide.
