Publication number: 20120103876Abstract: The present invention is directed to a method and a vehicle designed for cleaning beaches that have been contaminated with substances such as tar balls. The device utilizes an inclined screen assembly on a vehicle and a pivoted hopper supported below the lower end of the inclined screen. As the trailer is on or moved along the beach, contaminated sand is placed on an upper portion of the screen. Sand falls through the screen back down to the beach surface but larger contaminants such as tar balls roll or slide down the screen into a collection hopper. The inclination of the screen assembly may be adjustable.Type: ApplicationFiled: October 27, 2010Publication date: May 3, 2012Applicant: RB ENVIRONMENTAL, L.L.C.Inventor: John C. Allaire

Patent number: 7708496Abstract: The present invention relates to the removal of subsurface contaminants and methods of using 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. The present invention is focused on remediation of high viscosity hydrocarbons, such as heating oils or coal tars, with a combination of pre-injection of bio-co-solvent and surfactant (and polymer) flush approach.Type: GrantFiled: October 31, 2007Date of Patent: May 4, 2010Assignee: Surbec-Art Environmental, L.L.C.Inventor: Bor-Jier Shiau
