A process for dewatering sludge in which filtration through a filter cloth is assisted by the application of a vacuum.

CONT

Vacuum filtration is used to dewater a slurry under applied vacuum by means of a porous medium which retains the solid but allows the liquid to pass. ... In vacuum filter operation ... a rotary drum passes through a slurry tank in which solids are retained on the drum surface under applied vacuum. As the drum passes through the slurry, a cake is built up and water is removed by filtration through the deposited solids and the filter medium.
