摘要： The present disclosure describes a flow-electrode capacitive deionization (FCDI) desalination system and method of use. An FCDI desalination system is described employing one or more FCDI cells equipped with two coaxially oriented membranes mounted within a column housing capped with two end caps, each end cap comprising two carbon slurry ports and one water port. The column is lined with a chargeable sleeve capable of receiving a positive or negative charge. The annular space between the chargeable sleeve and the outside surface of the outer concentric membrane creates a flow path for a first carbon slurry to pass therethrough. The space between the inside surface of the outer concentric membrane and the outer surface of the inner concentric membrane creates a flow path for the saline water to be treated. The space within the inner annular portion of the inner concentric membrane creates a flow path for a second carbon slurry and contains a chargeable rod or wire capable of receiving an opposite charge. The first and second opposed end caps on the column are outfitted to continue these independent flow paths. As the saline water travels through its flow path, its salt ions are removed through the coaxial membranes via the two carbon slurries.

摘要： A flow-electrode cartridge unit and a submerged flow-electrode capacitive deionization device using the same are proposed. The flow-electrode cartridge unit includes a pair of porous current collector plates arranged to face each other in a spaced apart state from each other in a first direction, a pair of ion separation membranes positioned on respective outer surfaces of the porous current collector plates in the first direction, a channel frame for wrapping around the pair of porous current collector plates and the pair of ion separation membranes to expose each of the ion separation membranes in the first direction, thereby forming a flow electrode channel between the pair of porous current collector plates, a pair of communication holes formed in the channel frame and communicating the flow electrode channel to an outside, and an electrode terminal formed in the channel frame and electrically connected to the porous current collector plates.

摘要： Disclosed is a hybrid water-treating system. The system includes a raw-water supply bath having a predetermined volume and configured to receive raw-water containing high concentration organic contaminants; at least one electrolytic bath configured to receive the raw-water supplied from the raw-water supply bath and to produce first treated water, wherein a boron doped diamond (BDD) electrode is installed in the electrolytic bath; and at least one deionization bath configured to receive the first treated water discharged from the electrolytic bath and to produce second treated water, wherein flow-electrode capacitive deionization (FCDI) is performed when applying a first voltage to the deionization bath.
