ABSTRACT:
A filtering device for filtering a liquid includes a vessel having an inlet and outlet communicating with a chamber found within the vessel. A flexible, liquid permeable filtering bag is suspended within the chamber and receives liquid from the inlet, which is filtered by passing through the walls of the bag. The bag is supported away from the wall of the vessel by a liner which extends circumferentially around the bag and is provided with apertures for communicating liquid through the liner. Radially outwardly extending projections extend from the solid portion of the liner which define the apertures and engage the wall of the chamber to maintain the circumferentially extending portion of the liner to a predetermined distance from the wall of the vessel. Accordingly, passages around and over the projections are defined to thereby permit liquid fluid to communicate between the vessel and the liner to the outlet.
