ABSTRACT:
A process is provided for purifying salt-containing water into desired form, wherein a salt-containing water stream is mixed with hydrogen and then pumped into an electrochemical cell where hydrogen is ionized into protons. These protons migrating to the counter-electrode, under the influence of an applied potential, entrain liquid water. At the counter-electrode, protons recombine to form hydrogen while releasing liquid water. Hydrogen is recycled and participates into the process only as a vehicle for the transport of water. This process is particularly applicable to the purification of water with high salt content such as sea water.
Apparatus for carrying out the above process is also provided.
