Particle manipulation by ultrasonic waves

The goal of this project the goal is move particles to a specific position within a liquid using high frequency acoustic waves. This is done by applying a standing pressure wave on particles in a flow. Due to the difference in compressibility, particles tend to align on the nodes and by moving the nodes of the standing waves, the particles can be moved towards the side of the flow channel. Since this technique can be used for a wide variety of particles, applications range from (microbiological) analysis of drinking water to filtering of contaminated water in petrochemical industries.
