Maturity stage TRL 9 / CRI 3-4 - Commercial Scale Up / Multiple commercial Applications

Traditionally clarifiers are equipped with a Clifford (cylindrical skirt). The currents are directed towards the bottom and have a circular shape in which sludge is captured as a cloud. So that, sludge is spread and it is difficult to gather it and recycle to the aerated tank. Speed-O-Clar is a custom-made HDPE retrofit device improving primary or secondary clarifier performance. A cone shaped piece of equipment, installed at the inlet of circular clarifiers, directs influent onto a baffled plate, changing the direction of flow within the clarifier. This creates a centripetal flow at the bottom which make them more efficient and enhance the limit flow rate.
