Patent ID: 7416662

Claim:
In a water treatment system to gravitationally separate solids suspended in a liquid contained in said water treatment system, the water treatment system having a containment vessel bottom and a substantially vertical wall bounding the liquid, the improvement comprising density baffle comprising: a first corrugated panel member having an upper edge, a lower edge, a first lateral side, and a second lateral side, with a corrugated pattern running laterally across said first corrugated panel member from said first lateral side to said second lateral side; and a support flange integrally connected to said upper edge of said first corrugated panel member, and wherein said support flange is affixed to a substantially vertical wall of a water treatment system such that said first corrugated panel member slopes downward at an angle away from said substantially vertical wall toward an interior of a containment vessel and a containment vessel bottom of said water treatment system terminating at said lower edge and disposed in space relation to said containment vessel bottom, and wherein said first lateral side of said first corrugated panel member terminates at a first location along said corrugated pattern and said second lateral side of said first corrugated panel member terminates at a second location along said corrugated pattern such that a second lateral side of a second corrugated panel member of similar design is overlapped in a nested manner with said first lateral side of said first corrugated panel member and is directly affixed thereto without use of an additional support bracket, and such that a first lateral side of a third corrugated panel member of similar design is overlapped in a nested manner with said second lateral side of said first corrugated panel member and is directly affixed thereto without use of an additional joining structure.
