ccd counter current decantation

Countercurrent exchange - Wikipedia

Counter Current Decantation (CCD) is used in some facilities to extract water, totally clear of Uranium. Exchange current decantation depicted in centrifugal extractors as 1st stage Zippe-type centrifuges use countercurrent multiplication between rising and falling convection currents to reduce the number of stages needed in a cascade.
