Actiflo® recirculation

Rise Rate Rise rate of water is the flow rate (total hydraulic load) divided by the surface area of the clarifier. Most clarifiers operate between 0.75 gpm/ft and 1.25 gpm/ft, with the exceptions of inclined-plate settlers, which operate at higher rise rates, as high as 2.0 gpm/ft and the Actiflo recirculation clarifier which operates at a rise rate of at least 16 gpm/ft (Actiflo is a registered trademark of Veolia Water North America, Chicago, IL).
