ABSTRACT:
A filter of the type including a filter drum mounted within a settling tank containing a liquid to be filtered, with filtering flow drawn through a filter media on the outer surface of the drum, in which a fluid connection to the liquid circulation system is established by interfitting of tube sections as the filter drum is lowered into the tank at installation. Guiding members are included to properly position the drum as it is lowered to insure the tube sections move together as the filter drum is lowered. A valving arrangement is disclosed in one embodiment for isolating the particular drum filter from the circulation system upon removal. In another embodiment, an arrangement is utilized for producing intermittent rotation of the drum by engagement with the flights of a drag-out conveyor.
