A baffle system for a clarifier tank where the tank has a tank bottom, a periphery and a substantially vertical peripheral wall bounding the interior of the tank, said tank having an effluent channel. The baffle system includes a plurality of baffles mounted on the clarifier tank, each baffle having a baffle surface with a lower end and an upper end. The upper end of the baffle surface is coupled to a wall of the clarifier tank, the lower end of the baffle surface is disposed at a substantially 60° angle away from the side wall of the clarifier tank such that the baffle surface slopes downwardly and away from the side wall.

1. A baffle system in a clarifier tank having a tank bottom, a periphery and a substantially vertical peripheral wall bounding the interior of the tank, said tank having an effluent channel operating at an SOR (Surface Overflow Rate) with an associated density current of solids, said baffle system comprising: a plurality of baffles mounted on the clarifier tank, each baffle comprising:a baffle surface, said baffle surface having a lower end and an upper end, the upper end of said baffle surface being coupled to a wall of the clarifier tank, the lower end of said baffle surface being disposed, at a substantially 60° angle away from the side wall of the clarifier tank such that said baffle surface slopes downwardly and away from the side wall; andwhere the horizontal projection of said baffle into the center of the tank is determined using the following equation: HP=18″+a(D−30)D=diameter of the tank in feet;a=coefficient multiplier with the coefficient “a” is set to 0.3 inches per foot or greater, such that said plurality of baffles are arranged within said tank and dimensioned so as to deflect said density current of solids away from said peripheral wall and said effluent channel. 2. The baffle system of claim 1, wherein said baffle surfaces, further comprise mounting flanges for securing to said wall of said clarifier tank. 3. The baffle system of claim 2, wherein each of said baffle surfaces further comprise vent openings integrally molded within said mounting flange. 4. The baffle system of claim 1, wherein said horizontal projection is substantially 39 inches in a clarifier tank of 100 ft diameter. 5. The baffle system of claim 1, wherein said baffle surfaces each have a lower end flange. 6. The baffle system of claim 5, wherein said clarifier tank has a sludge blanket having a depth from the bottom of said tank bottom, and wherein said lower end flange of said baffle surfaces are positioned substantially 2 feet from the top of a sludge blanket of the tank. 7. The baffle system of claim 5, wherein said clarifier tank has a sludge blanket having a depth from the bottom of said tank bottom, and wherein said lower end flange of said baffle surfaces are positioned at a point midway between the average blanket height and the weir. 8. The baffle system of claim 1, wherein said upper end of said baffle surface is coupled to the peripheral wall of said clarifier tank. 9. The baffle system of claim 1, wherein said upper end of said surface is coupled to the wall of the effluent channel of said clarifier tank. 10. The baffle system as claimed in claim 1 wherein said SOR (Surface Overflow Rate) is measured in gallons per day per square foot of water surface area of said clarifier tank. 11. A baffle system in a clarifier tank having a tank bottom, a periphery and a substantially vertical peripheral wall bounding the interior of the tank, said tank having an effluent channel operating at an SOR (Surface Overflow Rate) with an associated density current of solids, said baffle system comprising: a plurality of baffles mounted on the clarifier tank, each baffle comprising:a baffle surface, said baffle surface having a lower end and an upper end, the upper end of said baffle surface being coupled to a wall of the clarifier tank, the lower end of said baffle surface being disposed, at a substantially 60° angle away from the side wall of the clarifier tank such that said baffle surface slopes downwardly and away from the side wall; andwhere the horizontal projection of said baffle into the center of the tank is determined using the following equation: HP=18″+a(D−30)D=diameter of the tank in feet;a=coefficient multiplier with the coefficient “a” is set to 0.3 inches per foot or greater, such that said plurality of baffles are mounted above an average sludge blanket height for said clarifier tank and dimensioned so as to deflect said density current of solids away from said peripheral wall and said effluent channel.
