Abstract:
The present disclosure describes a flow-electrode capacitive deionization (FCDI) desalination system and method of use. The system employs clusters of tubular membranes oriented parallel to each other, each membrane having an internal flow path capable of receiving an electrolyte slurry (carbon slurry) therethrough. Each tubular membrane further comprises an electrode coaxially extending through the entire length of the electrode. Preferably, adjacent electrodes within the cluster receive a positive or negative charge, respectively. The cluster of tubular membranes is nested within a flow chamber capable of receiving saline or brackish water to be flowed along the outside surfaces of the tubular membranes to cause selected ions, e.g., Na+, Cl— to pass through the membranes and into the carbon slurry circuit. The desalinated water then passes out of the flow chamber. The outer diameter of the electrodes can be optimized based on the inner diameter of the tubular membrane.

Claim (Index 1):
A flow-electrode capacitive deionization (FCDI) desalination cell comprising:\n a. a tubular housing having an upper end and a lower end, a first interior annular fluid flow space extending between the upper and lower ends, a feed solution inlet port proximate the lower end in fluid communication with the first interior annular space, and a treated solution outlet port proximate the upper end in fluid communication with the first interior annular space; b. an tubular upper end cap attached to the tubular housing upper end and comprising an internal annular upper end cap space, an upper seal member sealing the upper end of the tubular housing, and an outlet port in fluid communication with the internal annular upper end cap space, the upper seal isolating the internal annular upper end cap space from the tubular housing first interior annular space; c. an tubular lower end cap attached to the tubular housing lower end and comprising an internal annular lower end cap space, a lower seal member sealing the lower end of the tubular housing, and an inlet port in fluid communication with the internal annular lower end cap space, the lower seal isolating the internal annular lower end cap space from the tubular housing first interior annular space; d. a plurality of tubular membranes oriented in parallel relationship to each other, each membrane having a lower end, an upper end, an outer surface and an inner tubular space therebetween, each tubular member being mounted within the cell so that its lower end is in fluid communication with the internal annular lower end cap space, so that it passes in sealed fashion through the lower seal member, so that it extends through the first annular fluid flow space, so that it passes in sealed fashion through the upper seal member, and so that its upper end is in fluid communication with the internal annular upper end cap space, each tubular member connecting the lower end cap space and the upper end cap space in fluid communication; and e. a plurality of electrodes extended through each respective membrane inner tubular space, respectively, wherein approximately one half of the plurality of electrodes each has a positive polarity, wherein the remainder of the plurality of electrodes each has a negative polarity, and wherein the negative and positive polarity electrodes are evenly distributed through the plurality of electrodes to create a plurality of pairs of tubular membranes having opposite polarity;\n wherein the annular lower end cap space is capable of receiving a carbon slurry through the lower end cap inlet, wherein the carbon slurry is capable of moving through the inner tubular spaces of the plurality of tubular members into the annular upper end cap space and then out the upper end cap outlet.
