An electrochlorination system comprising an electrochemical cell including a housing having an inlet, an outlet, and an anode-cathode pair disposed within the housing, a source of a chloride-containing aqueous solution having an outlet fluidly connectable to the inlet of the electrochemical cell, and a source of an oxidizing agent fluidly connectable to the source of chloride-containing aqueous solution upstream of the electrochemical cell.

In-situ delivery systems for reaction product abatement in electrochemical cells

Electrochemical purification apparatuses for treating water and methods of assembling the devices are provided. The apparatuses may be cross-flow electrochemical devices. The devices may be assembled and sealed through masking and application of a potting material. The devices may comprise various structures configured to improve the current efficiency of the device, reduce leakage, and improve the distribution of potting material to the assembly.

Cross-flow electrochemical separation devices and methods of assembling same

Electrochemical devices and methods for water treatment are disclosed. An electrodeionization device () may include one or more compartments () containing an ionselective media, such as boron-selective resin (). Cyclic adsorption of target ions and regeneration of the media in-situ is used to treat process water, and may be driven by the promotion of various pH conditions within the electrochemical device.

Systems and methods for water treatment

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.

Low scale potential water treatment

Systems and methods for the desalination of seawater or brackish water for the purpose of obtaining potable water. Systems may include a combination of electrodialysis and electrodeionization modules. The system configuration and process controls may achieve low energy consumption and stable operation.

Electrodesalination system and method

An electrical purification apparatus and methods of making same are disclosed. The electrical purification apparatus may provide for increases in operation efficiencies, for example, with respect to current efficiencies and membrane utilization.
