  • Method and apparatus for remediating wastewater holding areas and the like
    Publication number: 20050016931
    Abstract: A method and apparatus for remediating waster water holding areas and the like includes a closed, foraminous dewatering membrane that is positioned adjacent to the wastewater holding area. Sludge and adjacent water on the bottom of the wastewater holding area are pumped in the form of a sludge slurry into the interior of the dewatering membrane. The water is removed from the sludge slurry by allowing gravitational forces to flow water through the dewatering membrane. The dewatering membrane is then opened, and the dewatered sludge is removed for depositing at an appropriate site.
