Patent ID: 8328025

Claim:
A baffle system in a clarifier tank having a tank bottom and a periphery and a substantially vertical peripheral wall bounding the interior of the tank, said baffle system comprising: a plurality of upper baffle surfaces, each mounted on the peripheral wall of the clarifier tank, said upper baffle surfaces each having a lower end and an upper end, the upper end of said upper baffle surfaces being coupled to the side wall of the clarifier tank wall, the lower end of said upper baffle surfaces being disposed at a substantially 60° angle away from the side wall of the clarifier tank such that said upper baffle surfaces each slope downwardly and away from the side wall forming a substantially continuous arrangement around the peripheral wall of the clarifier tank; a plurality of lower baffle surfaces, each of which substantially correspond to a corresponding one of said plurality of upper baffle surfaces, said lower baffles surfaces each having a lower end and an upper end, the upper end of said lower baffle surfaces being coupled to the lower ends of substantially corresponding upper baffle surfaces, and with said lower ends of said lower baffle surfaces being disposed at a 60° angle to the side wall of the clarifier tank, such that said lower baffle surfaces slope upwardly and away from the side wall said combination of said upper baffle surfaces and said coupled lower baffle surfaces forming a substantially continuous dosed density current baffle around the peripheral wall of the clarifier tank.
