Ultrasonic resonators are successfully used for the separation of suspended particles or biocells,
e.g. as cell filters in biotechnology. The scope of this paper is to investigate the separation
efficiency over time using yeast suspensions and its dependencies on true electrical power
input, liquid medium throughput and initial cell concentration. Data of systematic measurements
at different values of these process parameters will be shown and an attempt to model the
development of the number of cells passing the filter over time will be presented.
