  • Method of denitrifying wastewater
    Patent number: 8101081
    Abstract: Disclosed is a method of denitrifying a solution including introducing into the solution an amount of a carbon source within a duration and at a frequency so that indigenous heterotrophic bacteria deplete dissolved oxygen in the solution and obtain oxygen from nitrate in the solution. Related apparatuses and compounds also are disclosed.
    Type: Grant
    Filed: March 24, 2008
    Date of Patent: January 24, 2012
    Assignee: Hoot Aerobic Systems, Inc.

  • Apparatus for denitrifying wastewater
    Patent number: 8066880
    Abstract: Disclosed is an apparatus for denitrifying a solution that includes a denitrification tank configured to receive a portion of the solution for a period of time. Controlling an amount, duration and frequency of introduction of polyethylene glycol into the solution promotes indigenous heterotrophic bacteria depleting dissolved oxygen in the solution and obtaining oxygen from nitrate in the solution.

  • Compound for denitrifying wastewater
    Publication number: 20100163484
    Abstract: Disclosed is a method of denitrifying a solution including introducing into the solution an amount of a carbon source within a duration and at a frequency so that indigenous heterotrophic bacteria deplete dissolved oxygen in the solution and decompose oxygen from nitrate in the solution to obtain its combined oxygen. Related apparatuses and compounds also are disclosed.

  • Method for purifying perchloroethylene containing dichlorobutadiene
    Patent number: 5731482
    Abstract: Perchloroethylene containing contaminating amounts of dichlorobutadiene is treated with bromine, e.g., elemental bromine, in the presence of a free-radical initiator, thereby to produce perchloroethylene substantially-free of dichlorobutadiene and without significant loss of perchloroethylene. A bromine scavenger, e.g., trichloroethylene, can be added to the treated perchloroethylene to react with excess bromine that may be present in the perchloroethylene.
