Abstract: A method of washing particles in an acoustic chamber includes (a) flowing a suspension of particles in a suspension medium through a standing wave generated in a standing wave volume of the acoustic chamber to accumulate within the acoustic chamber at least some of the particles as raw particle concentrate; and (b) flowing a wash medium through the acoustic chamber to wash within the acoustic chamber at least some of the particles of the raw particle concentrate, and retaining within the acoustic chamber at least some washed particles.
