Claim:
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, 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 said wall of the clarifier tank such that said baffle surface slopes downwardly and away from said wall where 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” set to 0.3 inches per foot or greater.
