Abstract

The present invention deals with separation of particles in a fluid comprising particulate matter, and especially the invention relates to a method and an apparatus for separating particles, and more specifically for separating particles in a blood solution by means of an acoustic filter using ultrasound. Embodiments of the method and system for separation of a blood solution uses a stationary ultrasonic standing wave pattern (505) for collecting particles of a first particle type in the nodes of the standing wave pattern (505); and generating a flow of liquid through the standing wave pattern (505) carrying away particles of a second particle type.
