Claim:
An integrated perforated flocculating baffle system in a clarifier tank for gravitationally separating suspended matter from liquid, the clarifier tank having a bottom and at least one side wall bounding the liquid contained in the clarifier tank, said baffle system comprising: a plurality of interconnected baffles mounted within the clarifier tank dividing the clarifier tank into a flocculating and energy dissipation compartment and a settling compartment, wherein each said baffle comprises a solid section which is linear in a vertical cross section extending downwardly from a support within the clarifier tank and a plurality of sections which are linear in a vertical cross section and each have at least one opening alternating with a plurality of solid sections which are curved in a vertical cross section below said linear solid section; said baffles being secured together along their lengths in such a manner as to form a gap between adjacent baffles while forming a substantially rigid wall of baffles.
