ELECTRODEIONIZATION MODULE AND APPARATUS COMPRISING IT

摘要

The electrodeionization (EDI) module of the present invention comprises at least one ion-exchange membrane delimiting at least one desalting zone (11) and at least one concentrating zone (12) situated between electrodes (13, 14), each of which is provided with ion-exchange means, and is characterized in that the ion-exchange means present in a zone are comprised of either ion-exchange resin beads (17) or at least one non-woven or woven fabric (21, 22) made of ion-exchange fibers, the resin beads and the fabrics) being both present in the EDI module.
