    NEFCO Stamford Baffle 2.0 - Density Current Baffler System

    Density currents form in all activated sludge clarifiers. The dense influent cascades downward and becomes a current moving in a horizontal plane just above the sludge blanket, attracting lighter solids and short-circuiting the main clarification volume of the tank. The density currents carry the solids to the tank wall and deposit them into the effluent channel, increasing effluent suspended solids and reducing the clarifier’s hydraulic...

    NEFCO - Dual Surface Baffle System

    NEFCO’s Dual Surface Density Current Baffle was developed through the company’s CFD Baffle Study. This baffle is designed for larger clarifiers operating at very high flow, and has the potential to reduce effluent solids by as much as 80%. As a part of its CFD Baffle Design Study, NEFCO engineers began to explore alternative baffle configurations that might further improve baffle performance. These new configurations were inspired by the...
