The present invention is directed to a plate settler cover that prevents algae growth, prevents contamination from organic material, and provides structural support for a user who is standing or walking on the plate settler system. The plate settler covers can either float directly on standing water present in the system or may be structurally supported such that the plate cover is positioned above the surface of the water.

A roof panel of a sealed floating roof for a storage tank includes a first frame segment and a second frame segment. Each of the first and second frame segments includes a first depression configured to abut an adjacent top depression of a respective frame segment of a respective adjacent roof panel to form a walled trough to guide an automatic welder along a weld joint during a welding process. The roof panel also includes a panel component. The panel component includes a top sheet and a pan-shaped bottom sheet coupled to the top sheet. The pan-shaped bottom sheet is coupled to a respective upper lip of each of the first and second frame segments.
