Studies by the U.S. EPA and others show that density currents form in all activated sludge secondary clarifiers, regardless of size and shape, and have a significant, adverse effect on clarifier performance. The new Nefco Stamford Density Current Baffle System 2.0 is specifically designed to intercept and dissipate these currents and redirect their flow back into the main clarification volume of the tank, increasing hydraulic capacity and producing as much as a fifty percent reduction in total suspended solids. It has been called "...the most cost-effective improvement in clarifier performance available today." The new baffle design is the result of four years of CFD modeling.
