摘要: A method and apparatus for desalinization of salt water to render it potable, wherein the salt water at ambient temperatures is forced through multi-stages at high centrifugal velocities, generating heat to vaporize the water to water vapor, and separating and suspending the salt and other minerals in the water vapor. The centrifugal force separates the salt and other minerals for discharge separately from the water vapor or steam so that the water vapor may be condensed to essentially mineral-free potable water.
