ABSTRACT:
An apparatus and method are disclosed for filtering or separating particles. The apparatus has a motor coupled to a centrifuge rotor rotatable about an axis of rotation. A fluid chamber rotates with the rotor. A substance is supplied to the inlet of the chamber. At least one of the motor and the substance supply are controlled to maintain a saturated fluidized bed of first particles within the fluid chamber while causing second particles to be retained in the chamber.
