Abstract
A screen filter device for removing solid particles from a liquid is disclosed. The device includes a spray or shower for cleaning the filter media. In operation, a first liquid containing particulate matter flows over the filter media having an opening formed therein. Spray nozzles are arranged with respect to the filter media to impinge cleansing liquid on the surface of the filter media over which the first liquid flows. The cleansing liquid carries particulate matter continuously and in a spiral fashion towards the opening within the filter media.
