Abstract
The invention disclosed is a desalination apparatus for removing salt from seawater. The apparatus operates on the principle of reverse-osmosis whereby a feed solution containing seawater is separated into a product solution of decreased salt concentration and an exhaust solution of increased concentration. An evacuated enclosure is included to reduce windage losses and power consumption.
