Zusammenfassung:An intake screen assembly having a domed or dome-like upper screen structure mounted above a central intake structure. The domed or dome-like upper screen structure is constructed such that an interior portion closely conforms to a key flow velocity isosurface without requiring additional internal flow controls or flow modifying structures to achieve desired flow velocities at any point on a screen surface. The central intake structure can define an upper flange surface to which the domed or dome-like upper screen structure is operably coupled. The domed or dome-like upper screen structure can be mounted to a perimeter of the central intake structure at a point spaced away from an intake opening. The domed or dome-like upper screen structure can include a plurality of arcuate or flat filter screen panels. An air burst system can be attached to the central intake structure to backwash the domed or dome-like upper screen structure.
