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.
A device for producing deeply desalted water, comprising: a dielectric housing; an inlet for the water being treated located in said dielectric housing; an outlet for the water being treated, located in said dielectric housing; electrodes mounted in said dielectric housing adapted to be connected electrically with a current source, the electrodes being rods arranged in parallel substantially in the vertexes of a regular hexagon, adjacent electrodes in each hexagon having alternating polarity; ion-exchange members located in said dielectric housing and made in the form of tubes; each of said ion-exchange membranes concentrically surrounding and having the same polarity as a corresponding one of said electrodes; desalinization chambers defined by said ion-exchange membranes and by the walls of said dielectric housing communicating with one another; said chambers being substantially filled with ion-exchange resins intended for the sorption of salt ions from the water being treated; brine chambers each of which is defined by a corresponding membrane; said brine chambers being adapted to have water passed therethrough for removing salt ions; and a means for cooling said electrodes.
