Abstract: An electrochemical cell includes a cathode and an anode disposed in a housing. Each of the cathode and anode portions extending radially outward from a region proximate a central axis of the housing. A surface area of an active surface of the anode is greater than a surface area of an internal surface of the housing. A surface area of an active surface of the cathode is greater than a surface area of an internal surface of the housing.

Abstract: An electrochemical separation system may be modular and may include at least a first modular unit and a second modular unit. Each modular unit may include a cell stack and a frame. The frame may include a manifold system. A flow distributor in the frame may enhance current efficiency. The flow distributor may define a labyrinth flow path for improved current efficiency.

Abstract: An electrochemical treating device having low scale potential is disclosed. The device has a variety of configurations directed to the layering of the anionic exchange and cationic exchange. The treatment device can also comprise unevenly sized ion exchange resin beads and/or have at least one compartment that provides a dominating resistance that results in a uniform current distribution throughout the apparatus.

Abstract: A low energy water treatment system and method is provided. The system has at least one electrodialysis device that produces partially treated water and a brine byproduct, a softener, and at least one electrodeionization device. The partially treated water stream can be softened by the softener to reduce the likelihood of scale formation and to reduce energy consumption in the electrodeionization device, which produces water having target properties. At least a portion of the energy used by the electrodeionization device can be generated by concentration differences between the brine and seawater streams introduced into compartments thereof. The brine stream can also be used to regenerate the softener.
