    Abstract: An acoustophoresis device which includes a substantially vertical flow path of the fluid mixture in order to improve separation of particles / secondary fluid from a primary fluid is disclosed. The vertical flow path reduces velocity non-uniformities in the acoustic chamber resulting from gravity forces. The device includes an acoustic chamber in which multidimensional acoustic standing waves are generated. The fluid can be introduced into the acoustic chamber using a dump diffuser in which a plurality of inlets enter near the bottom of the acoustic chamber such that flow symmetry reduces both, gravity driven flow non-uniformities, and any flow interference effects between inlet mixture flow into the acoustic chamber and the continuous gravity driven particle cluster drop out.

    Abstract: A system for enhancing the separation of particles or fluids from water is disclosed. A settling tank or skim tank is provided with an open submersible acoustophoretic separator. In a skim tank, the separator captures and holds oil droplets or particles, permitting them to coalesce until they are large enough and have sufficient buoyant force to float to the top of the tank. In a settling or sediment tank, separator captures and holds particles until they are large enough that the force of gravity causes them to settle out of the water. The acoustophoretic device thus speeds up separation of the particles or droplets from the water.

    Abstract: A system having improved trapping force for acoustophoresis is described where the trapping force is improved by manipulation of the frequency of the ultrasonic transducer. The transducer includes a ceramic crystal. The crystal may be directly exposed to fluid flow. The crystal may be air backed, resulting in a higher Q factor.

    Abstract: An acoustic wave with an acoustic field with a large number of multi-directional gradients can provide an edge effect that be used to form an interface region relative to the acoustic wave. The interface region can block material with certain characteristics related to the nature of the interface region. Other material that is less influenced by the acoustic properties of the interface region can pass through the acoustic wave. This technique permits separation of materials using the edge effect and interface region.
