Abstract
Utilization of ultrasound is considered as an alternative technique for the separation of particles. The authors studied particle behavior in ultrasonic waves in water with frequencies of 23 kHz or 97 kHz. As a result, the particle aggregation types of bands, clump and points are observed, depending on the frequency, power of ultrasound and particle diameter. It was found that some of the aggregation locations for the clump and the point aggregations are reproducible, respectively.
