Abstract
A method of saltwater desalination and fresh water recovery comprises spraying a mixture of saltwater droplets substantially in the range of 7 to 30 microns in diameter and compressed air with a mass flow ratio of about one part compressed air to 10 parts saltwater droplets, without heating the droplets, into a chamber at a velocity of at least 200 meters per second to progressively vaporize the saltwater droplets for effectuating precipitation of dissolved impurities and salts from the vaporizing saltwater droplets and accumulation of a fresh water droplet suspension within the chamber and evacuating the accumulated fresh water droplet suspension out of the chamber at a rate controlled by a blower to maintain the fresh water droplets in suspension and washing fresh water droplets from the evacuated freshwater droplets suspension and collecting the fresh water.
