Abstract
A method for desalination of sea water using a main electrochemical generr which has an anode compartment through which the water to be desalinated is fed and which causes formation in the solution of chlorates and perchlorates, removal of the latter being effected by a potassium salt such as potassium bicarbonate. The insoluble matters are separated from the solution, while the residual salts dissolved therein are oxidized at the anode of secondary electrochemical generator(s), under the form of persalts apt to be precipitated and removed by settling or filtration. The insoluble matters obtained at the various stages of this treatment can be decomposed by heating or electrolysis or under the action of a strong acid such as hydrochloric acid. The power consumed during desalination may be wholly or partly supplied by the above mentioned main electrochemical generator and secondary electrochemical generators. This method may be used to provide fresh water for agricultural, industrial or domestic purposes.
