ABSTRACT:
The present invention provides a filter apparatus having a filter vessel into which liquid to be filtered is inlet near the bottom of the vessel. The liquid rises in the vessel and is forced through a filter screen running the height of the vessel. After flowing through the filter screen, the filtered liquid enters an annular enclosure outside the filter screen. The filtered liquid rises in the enclosure to the height of a discharge outlet near the top of the enclosure wall. This assures the even depositing of solids filtered from the liquid along the entire height of the filter screen.
