Abstract: Energy-efficient separation of particulates from fluids is based on determining particulate mass removal as a function of applied energy. Energy-efficient ultrasonic field powers and exposure durations are applied to a particulate containing fluid, and particles removed. In some cases, ultrasonic exposures are selected that provide the maximum particulate removal per applied energy.

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.
