ABSTRACT:
A filter for filtering water, e.g. seawater, for industrial use, in condensers for steam turbines, for example, comprising a spiral housing having a strainer or filter member and having an inlet inclined with respect to the housing and an outlet generally in alignment with the strainer or filter member which is preferably cylindrical. The inlet and spiral shaped housing combine to provide a sweeping water flow pattern along the periphery of the strainer or filter member. A partition is disposed parallel to the axis of the strainer or filter member between the strainer or filter member and the spiral housing, remote from the inlet relative to the flow of water around the strainer or filter member. Solids are collected in an area defined by the partition and parts of the strainer or filter member and spiral housing immediately upstream thereof. Solids may be continuously or intermittently discharged from the solids collecting area.
