A convergent nozzle is in a flow path from a liquid inlet of the ejector and a liquid outlet of the ejector. A convergent end of the convergent nozzle has a smaller cross-sectional area than an inlet of the convergent nozzle. The convergent nozzle is sized to increase a velocity of the liquid to supersonic velocities and decrease a pressure of the liquid. A low pressure housing includes a low pressure inlet into an interior of the low pressure housing. A convergent-divergent nozzle includes a mixed liquid inlet in fluid communication to receive fluid from the convergent nozzle and the low pressure housing.

Disclosed herein are systems and methods for desalination of salt water based on an engineered acoustic field that causes constructive and destructive interference at precomputed spatial positions. The engineered acoustic field can cause high-pressure and low-pressure regions where desalination membranes are located. The induced pressure from the acoustic field can force pure water through the membranes leaving ionic and dissolved molecular species behind.
