  • Water desalination process using ion selective membranes
    Patent number: 6998053
    Abstract: The invention is directed to an improved desalination process to produce potable water. The process represents an improvement of hybrid of membrane and desalination technologies. The improvement of the invention comprises the operation of an ion selective membrane at a variable pressure as a function of the cost of electricity to form a softened salt water that is blended in variable proportions, to increase the top operating temperature of the desalination system and increase recovery of potable water, with untreated salt water.
