Abstract
A filter system for filtering solids includes a filtration tank for receiving a slurry containing the solids to be filtered. A filter assembly including a plurality of filter cells each having a filter medium at an exterior and a cavity at an interior is lowered into the filtration tank using a transport device carrying the filter assembly. A vacuum transfer system is connected to the filter assembly so as to transfer a vacuum to an interior of the filter cells. The vacuum transfer system is operable to perform the filtering and to retain the filtered solids while the transport device moves the filter assembly relative to the filtration tank.

A filter system for filtering solids, the filter system comprising:
- a filtration tank for receiving a slurry containing the solids to be filtered;
- a filter assembly including a plurality of filter cells each having a filter medium at an exterior and a cavity at an interior;
- a transport device carrying the filter assembly;
- and
- a vacuum transfer system connected to the filter assembly so as to transfer a vacuum to an interior of the filter cells,
- wherein the vacuum transfer system is operable to perform the filtering and to retain the filtered solids while the transport device moves the filter assembly relative to the filtration tank.
A process of filtering solids comprising:
- moving a filter assembly into a filtration tank for receiving a slurry containing the solids to be filtered, the filter assembly including a plurality of filter cells each having a filter medium at an exterior and a cavity at an interior;
- filtering the solids;
- and
- after filtering, moving the filter assembly out of the filtration tank,
- wherein a vacuum is applied to the interior of the filter cells during at least one of the filtering and the moving of the filter assembly.
A process for washing a filter cake comprising:
- moving a filter assembly into a first wash tank for receiving a wash liquor, the filter assembly including at least one filter cell having a filter medium at an exterior on which the filter cake is formed and a cavity at an interior;
- and
- washing the filter cake by applying a vacuum to the interior of the at least one filter cell so that the wash liquor moves through the filter cake at the exterior into the cavity.
