Centrisys/CNP, a leader in decanter centrifuge technology and systems for nutrient recovery and sludge optimization, has announced their exclusive distributorship for the Passavant hydrograv adapt System in North America (U.S. patent pending).
Unlike fixed inlet structures for secondary clarifiers, the Passavant hydrograv adapt System consistently and continuously adjusts to current loading in a clarifier. If the loads are low, the hydrograv adapt automatically shifts the inlet elevation and opening height to a low position, introducing the mixed liquor below the sludge blanket. As the loads increase, the hydrograv adapt system shifts itself to a higher elevation and opening height, ensuring ideal hydraulic conditions for the operation of the secondary clarifiers and avoiding sludge overflow.
