Bor-Jier Shiau has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • In-situ surfactant and chemical oxidant flushing for complete remediation of contaminants and methods of using same
    Patent number: 7021863
    Abstract: The present invention relates to removal of subsurface contaminants and methods of same. In more particular, but not by way of limitation, the present invention relates to an integrated method for remediating subsurface contaminants through the use of a low concentration surfactant solution (and methods of making and using novel surfactant solutions) followed by an abiotic polishing process to thereafter achieve a substantially reduced subsurface contaminant concentration that surfactant flushing alone cannot achieve.
    Type: Grant
    Filed: July 30, 2004
    Date of Patent: April 4, 2006
    Assignee: Surbec Environmental, L.L.C.
    Inventor: Bor-Jier Shiau
