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.

Particle filter method

Particle filter apparatus

A fluid chamber and method are disclosed for filtering or separating particles. The fluid chamber includes a wall extending between an inlet and outlet 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.

Method for separating particles

Apparatus for separating particles

A fluid flow control apparatus including a fluid flow portion configured to receive a flexible fluid container and an actuating portion which provides a variable force to the fluid flow portion thereby causing the fluid flow portion to pressurize the flexible fluid filled container.
