摘要: Method and apparatus for separating particles (1) which are dispersed in a dispersion medium, whereby an ultrasonic standing wave (3) is generated by means of composite resonator vessel (8) containing (2), the frequency said preferably being neighborhood characteristic (fo). In order to achieve, better separation it provided that amplitudes (V) sound particle velocity appear field chosen slightly smaller than upper threshold amplitude (Vmax), pressure forces on (1), result from acoustic stream medium caused applied sound, equivalent longitudinal holding areas antinodes (11) nodes (12), furthermore driven as precisely possible tuned one resonant frequencies (fn).
