Abstract: A system and method for dewatering sludge, slurry, sediment, or like material includes a dewatering device having a permeable, collapsible enclosure positioned within an impermeable, collapsible enclosure. The enclosures can be substantially tubular and formed from sheets with sealed edges. A fill pump connectable to an inlet on the device pumps the material into the permeable enclosure and inflates the enclosures. Liquid from the material is allowed to flow into an at least partial space between the enclosures and can be drained from an outlet on the device communicating with the space. Preferably, a separation layer in the form of a mesh is at least partially inserted in the space between the enclosures. A vacuum pump connectable to the outlet collapses the impermeable enclosure about the permeable enclosure and draws liquid from the space between the enclosures.
