ABSTRACT:
A method of and apparatus is disclosed for water desalination including steps of transferring water vapor from salt-water in a vaporization zone7, via a water vapor transfer zone12, to a condensation zone11, and condensing the water vapor into fresh-water. The water vapor transfer zone 12 is maintained substantially free of any gas other than water vapor. Heat is supplied to the vaporization zone7and extracted from the condensation zone11, at relative rates such that there is a net transfer of water from the vaporization zone to the condensation zone. Also disclosed is a method of and apparatus for degassing salt water using at least two degassing chambers17A,17B each provided with a valved vent 47 and a valved inlet21,29,90,91, with a valved pipe circuit17a,72-82,85-87, having a pump 71. pump and valved circuit transfer water from one chamber17A to another1713so as to reduce the pressure in the one chamber17A inducing the release of dissolved gas, and expelling gas above the water out of the other chamber1713. The direction of water transfer is then reversed so as to release dissolved gas in the other chamber17B and expel gas in the one chamber17A.
