Abstract: Abstract We have developed a unique particle-separation technique based on size that uses kHz-band ultrasound irradiation in water. Dispersed-millimeter-size particles in dissolved-gases water form themselves into a spherically flocculated particle swarm (SFPS). With the changes… read more here.
