Interchangeable screen panels for a traveling water screen

摘要

A traveling water screen is provided with a support frame having a transverse tray for accommodating a conventional screen panel of a specific configuration or alternatively a modified screen panel having an integral pan for positioning over the transverse tray to provide special handling of seasonally varying screened material. A non-abrupt smooth transition at a transition margin between the screen material and the integral pan allows aquatic life forms to flow from the screen into the integral pan when the screen is backwashed without the aquatic material getting lodged between a screen retaining means and the screen.
