ABSTRACT:
Method and apparatus by which contaminants are removed from a liquid flowing through a filter vessel having an inlet for providing a contaminated liquid flow into one end thereof and an outlet through which filtered liquid can exit the vessel. A filter screen supports a relatively large quantity of particulate filter media within the filter vessel on the filter screen for normal filter operation and captures contaminants by flowing contaminated liquid through the inlet while filtered liquid exits through the filter screen and outlet, leaving the contaminants on the filter media. The system automatically occasionally cleans the media in a unique cleaning cycle, that includes one or a plurality of closed loop flow paths that fluidizes the media within one filter vessel and cleans the media externally of the filter vessel by flowing the fluidized filter media along the closed loop flow path. The closed loops each include a fluidizing nozzle in the filter vessel and a scrubber vessel externally thereof to fluidize the media while concurrently flowing the fluidized media along the closed loop where it is scrubbed and returned to the filter vessel as cleaned media while dirty scrub water is discharged from the scrub vessel and leaves the system.
