Abstract
The present disclosure is directed to ion-exchange systems and devices that can monitor key parameters related to the performance of the ion-exchange device. Specifically, the ion-exchange systems and devices disclosed herein can provide real time voltage drop across groups of membrane pairs using diagnostic spacer borders between the pairs. In addition, the ion-exchange systems and devices disclosed herein can monitor the compression force applied by the compression plates holding the ion-exchange systems and devices together.
Claims5
An ion-exchange device comprising:
- a pair of compression plates, wherein at least one of the compression plates comprises a strain gauge on an outer surface of the at least one compression plate;
- a pair of electrodes comprising an anode and a cathode between the pair of compression plates;
- a first ion exchange membrane and a second ion exchange membrane between the pair of electrodes, wherein the first ion exchange membrane comprise at least two inlet or outlet ports,
- wherein the strain gauge is located at a position on the outer surface of the at least one compression plate corresponding to a point between the at least two inlet or outlet ports of the first ion exchange membrane.
