Abstract

Systems and methods for electrochemical separation are provided. An electrochemical separation device may include at least one cell pair wound around an electrode to from a bundle having a racetrack configuration.

Claims (8)

1. An electrochemical separation device, comprising:

a first electrode comprising a straight section with a semi-circular section at each end to define a substantially elongated S-shaped anode;

at least one cell pair comprising an anion exchange membrane and a cation exchange membrane wound around the first electrode to form a bundle; and

a second electrode surrounding the bundle.

2. The device of claim 1 , wherein the first electrode comprises an anode and wherein the second electrode comprises a cathode.

3. The device of claim 1 , wherein the first electrode further comprises a fastening tab at each end to secure the at least one cell pair.

4. The device of claim 3 , further comprising a spacer configured to maintain a predetermined distance between first and second segments of the anode.

5. A water treatment system, comprising the electrochemical separation device of claim 1 .
