Abstract
A low energy desalination system with a venturi device includes a saline water feed, a pump, and a venturi device. The pump provides saline water to the nozzle of the venturi device. The fluid flowing through the nozzle speeds up at the throat or constricted region of the device. This results in a reduction in pressure at the throat of the device. The reduced pressure at the throat of the device makes the fluid susceptible to evaporation which causes a certain amount of water to evaporate from the saline water. Freshwater vapor from the fluid flows through a freshwater vapor outlet at the throat of the venturi device to a freshwater tank and the concentrated brine remaining in the venturi device flows toward the diffuser of the venturi device and then to a brine tank.
