ABSTRACT:
A device is proposed for producing deeply desalted water. The device comprises a dielectric housing in which cooled electrodes and ion-exchange membranes are located. The electrodes are rods located parallel with respect to one another in vertexes of at least one regular hexagon with alternating polarity. Each membrane is made in the form of a tube and located concentrically to the corresponding electrode, the polarity of the membrane and of the electrode being the same. The device comprises desalinization chambers for sorption of the salt ions from the water being treated, said chambers being filled with ion-exchange resins. The desalinization chambers are formed by the membranes, located between them, and connected with each other. The device also contains brine chambers for removing the salt ions with the water being passed through the chambers. Each brine chamber is defined by one of the corresponding membranes.
The proposed device is small in size, highly efficient, reliable and safe in operation.
