  • Ultra low power acoustic separation
    Patent number: 11395982
    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.
