An apparatus and method are disclosed for filtering or separating particles. The apparatus has 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. A saturated fluidized bed of first particles forms within the fluid chamber and obstructs flow of second particles through the chamber. Additive substances alter sedimentation velocity of the first particles to modify the filtration characteristics of the saturated fluidized bed.

[ What is claimed is:] [1.] A method of separating first particles from second particles, the method comprising the steps of:rotating a centrifuge rotor about an axis of rotation, the rotor having an associated fluid chamber rotatable therewith, the fluid chamber having an inlet and an outlet;controlling rotation of the rotor;altering sedimentation velocity of the first particles;passing a quantity of the first particles into the inlet of the rotating fluid chamber;forming, with the first particles, a saturated fluidized bed within the fluid chamber; andflowing into the fluid chamber inlet liquid having at least a quantity of the second particles dispersed therein while simultaneously maintaining the bed within the fluid chamber, so that the bed substantially prevents flow of the second particles from the fluid chamber inlet to the fluid chamber outlet while substantially permitting flow of the liquid and a portion of the first particles to the outlet.
