ABSTRACT:
A selectively removable gravitational and vacuum sludge filtration apparatus and method that provides for retrofit into a container and separation of the sludge solids from the sludge liquids therein. A pair of spaced vertically oriented filter assemblies each define a filtrate cavity therein and are connected by separator plates. The filter assemblies permit the flow of sludge liquids into the filtrate cavity, but not sludge solids. A separator divides each filtrate cavity into two cavity sections, a first filtrate cavity and a second filtrate cavity. Filtrate drains into first and second filtrate cavities by either vacuum or gravitational drainage, depending on the level of sludge within the container. Vacuum drainage occur in first or second filtrate cavity if either cavity is situated below the level of the sludge within the container. A first and second filtrate evacuation means provide for the evacuation of filtrate from the first and second filtrate cavities by the use of a vacuum pump. A set of fasteners hold the filter assemblies in the container and bias the filter assemblies against the container bottom. The fasteners may be released to provide for removal of the sludge filtration system from the container. Functionally applying this sludge filtration system provides a method of retrofitting a container with a sludge filtration system and removing filtrate from a sludge in the container.
