Abstract: A sludge filtration system for separating the sludge liquids from the sludge solids. A container provides a basin for receiving and holding the sludge. Within the container, a first filter assembly, positioned proximal the container bottom, defines a first filtrate cavity. The first filter assembly is maintained below the sludge level so that a pump, in flow communication with the first filtrate cavity, provides for vacuum evacuation of the first filtrate cavity. Placing a valve in the first filtrate discharge conduit facilitates selective vacuum evacuation or gravitational evacuation of the first filtrate cavity. A second filter assembly extends about the inside perimeter of the container cavity proximal the container side walls. In addition, the second filter assembly extends from proximal the container bottom to the container top end. The second filter assembly defines a second filtrate cavity. A second filtrate discharge conduit provides for gravitational evacuation of the second filtrate cavity. Providing a valve in the second filtrate discharge conduit and providing a second pump in flow communication therewith facilitates selective vacuum evacuation or gravitational evacuation of the second filtrate cavity. Functionally applying the aforementioned apparatus having a sludge therein provides a method of dewatering sludge.
