A density current baffle for use in a clarifier tank maintains a first baffle portion having a lower end, an upper end and an intermediate central portion. The lower end of the baffle portion is coupled to a side wall of the clarifier tank and the upper end of the baffle portion is disposed, at a predefined angle, away from the side wall of the clarifier tank such that the first baffle portion slopes upwardly and away from the side wall.

What is claimed is: 1. A density current baffle for use in a clarifier tank, said density baffle comprising: a first baffle portion having a lower end, an upper end and an intermediate central portion, said lower end of said baffle portion being coupled to a side wall of said clarifier tank, said upper end of said baffle portion being disposed, at a predefined angle, away from said side wall of said clarifier tank such that said first baffle portion slopes upwardly and away from said side wall, and wherein said upper end is configured to receive a mounting bracket, said mounting bracket having a first end coupled to said end flange and a second end coupled to said side wall of said tank wall, said mounting bracket being a downwardly sloping panel member which together with said first baffle portion form a substantially closed baffle, so that solid materials may be prevented from building up behind said upwardly sloping central baffle portion. 2. The density current baffle as claimed in claim 1, wherein said angle of attachment of said first baffle portion to said tank wall is substantially in the range of 35°to 60°. 3. The density current baffle as claimed in claim 1, wherein said angle of attachment of said first baffle portion to said tank wall is about 45 degrees. 4. The density current baffle as claimed in claim 1, wherein the clarifier tank has a water level, said baffle being located below the water level of the clarifier tank. 5. The density current baffle as claimed in claim 1, wherein the baffle further comprises an end attachment bracket intregally formed with the baffle as a one piece member. 6. The density current baffle as claimed in claim 5, wherein said baffle further comprises a rigidizing flange depending upward from said upper edge of baffle for providing enhanced rigidity to the baffle. 7. The density current baffle as claimed in claim 5, wherein the end attachment bracket further comprises a mounting flange securable to the tank wall and a mounting surface for receiving the first lateral side of the baffle of a next adjacent density current baffle. 8. The density current baffle as claimed in claim 1, wherein the peripheral wall of the clarifier tank has a radius of curvature, and wherein the lower end of the baffle has a radius of curvature which corresponds to the radius of curvature of the clarifier tank. 9. A density current baffle for use in a clarifier tank, said density baffle comprising: a first baffle portion having a lower end, an upper end and an intermediate central portion; an angled attachment bracket coupled to said first baffle portion for securing the baffle to the clarifier tank wall so that said upper end of said baffle portion is disposed, at a predefined angle, away from said side wall of said clarifier tank such that said intermediate central portion of said first baffle portion slopes upwardly and away from said side wall; and an upper plate having a lower edge connection for coupling said upper plate to said upper end of said first baffle portion and an upper wall flange for attachment of the upper plate to the side wall of said clarifier tank, said upper plate being disposed, at a predetermined angle, away from said side wall of said clarifier tank such that said upper plate slopes downwardly and away from said side wall. 10. The density current baffle as claimed in claim 9, wherein said attachment bracket is coupled to said baffle at a first end of said baffle. 11. The density current baffle as claimed in claim 9, wherein said attachment bracket is intregally molded with said baffle from a reinforced fiberglass composite. 12. A density current baffle for use in a clarifier tank, said density current baffle comprising: a first baffle portion having a lower end, an upper end and an intermediate central portion, said lower end of said baffle portion being coupled to a side wall of said clarifier tank, said upper end of said baffle portion being disposed, at a predefined angle, away from said side wall of said clarifier tank such that said first baffle portion slopes upwardly and away from said side wall; and an upper plate having a lower edge connection for coupling said upper plate to said upper end of said first baffle portion and an upper wall flange for attachment of the upper plate to the side wall of said clarifier tank, said upper plate being disposed, at a predetermined angle, away from said side wall of said clarifier tank such that said upper plate slopes downwardly and away from said side wall. 13. The density current baffle as claimed in claim 12, further comprising a relief vent mounted within said upper plate. 14. The density current baffle as claimed in claim 12, further comprising mounting legs for securing the lower end of said first baffle portion to said side wall so that said lower end of said first baffle portion is spaced apart from said tank wall so as to allow water to flow behind said baffle. 15. The density current baffle as claimed in claim 14, further comprising a plurality of relief vents mounted with said upper wall flange so as to allow water to flow behind said spaced apart first baffle portion and out of said plurality of relief vents in said upper plate. 16. The density current baffle as claimed in claim 12, wherein said upper end of said baffle portion is provided with an end flange for receiving a mounting bracket, said mounting bracket having a first end coupled to said end flange and a second end coupled to said side wall of said tank wall. 17. The density current baffle as claimed in claim 12, wherein said angle of attachment of said first baffle portion to said tank wall is substantially in the range of 35°to 60°.
