Abstract : An apparatus and process for desalination of seawater using a hydrophobic vapor permeable membrane. Heated seawater is passed across one surface of a membrane at rates which cause the flow to be turbid such that its turbidity is characterized by Reynolds numbers in excess of 1000. Fresh water is passed across the other surface of the membrane to act as a condenser and collector of vapor which passes through the membrane.
