<p>An apparatus and method are disclosed for filtering or separating particles. The apparatus has a centrifuge rotor (12) rotatable about an axis of rotation. A fluid chamber (22) rotates with the rotor. A substance is supplied to the inlet (28) of the chamber. A saturated fluidized bed of first particles forms within the fluid chamber and obstructs flow of second particles through the chamber. In an embodiment of the invention, additives substances alter sedimentation velocity of the first particles to modify the filtration characteristics of the saturated fluidized bed. The fluid chamber includes a wall extending between an inlet (28) and outlet (32) to form a fluid chamber interior. The interior converges from a position of maximum cross-sectional area toward the inlet. A groove or a step may be formed on an inner surface of the fluid chamber wall to improve particle separation within the fluid chamber.</p> |
