The present invention provides a device and a method for separating particles from fluids using ultrasound, laminar flow, and stationary wave effects comprising a micro-technology channel system with an integrated branching point or branching fork, and a single ultrasound source. One of the characteristics of the invention is that the single ultrasound source, which generates the standing waves, excites the complete structure including the channel system. No special reflectors or the like are needed. Extremely thin dividers can separate the flow, thereby enhancing the effectiveness of the device. The device could be manufactured in silicon and the ultrasound energy could preferably be delivered by a piezoelectric element.
A device for separating suspended particles from a fluid, comprising a channel unit arranged in a plate having first and second opposing great surfaces, said channel unit including a base stem channel having substantially parallel or near parallel base stem walls perpendicular to said surfaces, said base stem channel having an inlet and, opposite said inlet, a branching point connected to two or more different outlets;
A method for separating particles from fluids using ultrasound, laminar flow, and stationary wave effects comprising the steps of:
