Abstract

A method of water desalination in a filter press may comprise: providing a chamber between two filter plates in the filter press, the chamber being lined by filter cloths; substantially filling the chamber with a plurality of beads; pumping water into the chamber filled with the beads; heating the water in the chamber; and collecting water vapor generated by the heating; wherein salts precipitate in the chamber during the heating. Furthermore, during the heating, the chamber may be vacuum pumped to facilitate removal of water vapor. The beads may be reused in the chambers of the filter press.
