  • Zero-valent metal emulsion for reductive dehalogenation of DNAPLs
    Patent number: 7037946
    Abstract: A zero-valent metal emulsion is used to dehalogenate solvents, such as pooled dense non-aqueous phase liquids (DNAPLs), including trichloroethylene (TCE). The zero-valent metal emulsion contains zero-valent metal particles, a surfactant, oil and water. The preferred zero-valent metal particles are nanoscale and microscale zero-valent iron particles.
    Type: Grant
    Filed: October 31, 2003
    Date of Patent: May 2, 2006
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
    Inventors: Debra R. Reinhart, Christian Clausen, Cherie L. Geiger, Jacqueline Quinn, Kathleen Brooks

  • Use of ultrasound to improve the effectiveness of a permeable treatment wall
    Patent number: 6013232
    Abstract: A method for increasing the effectiveness of a permeable treatment wall is described. The method includes the introduction of ultrasonic radiation in or near the wall. A permeable treatment wall is also described which has an ultrasonic radiation generating transducer in or near the wall. Permeable treatment walls are described as having either a well vertically extending into the wall, or a rod vertically extending into the treatment wall. Additionally, a method for adapting a permeable treatment wall to allow for the introduction of ultrasonic radiation in or near the wall is described.

  • Apparatus for measuring gas emission rate from soil
    Patent number: 5355739
    Abstract: Gas flux rate from a surface is measured using an elongated tubular housing having a lower open end and an upper open end with a support positioned within the housing a predetermined distance from the lower open end. A gas sampling wand extends into the housing from the upper open end and is supported on the support. The wand has a lower open end at the support generally co-planar with the lower open end of the housing. An air baffle is coupled to the upper open end of the housing for reducing velocity and pressure fluctuations of atmospheric air entering the housing from the upper end. A detector is coupled to the wand for measuring the concentration of selected gases within the housing. A funnel-shaped hood circumscribes the lower open end of the wand and increases the sample collection area of the wand. An air pump is coupled to the wand for drawing air and gases into the wand from the area adjacent the lower open end of the housing.
