A method and apparatus for remediating wastewater 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.
