Electrodialysis reversal (EDR) is an electrodialysis reversal water
desalination membrane process that has been commercially used since
the early 1960s. An electric current migrates dissolved salt ions,
including fluorides, nitrates and sulfates, through an electrodialysis
stack consisting of alternating layers of cationic and anionic ion
exchange membranes. Periodically, the direction of ion flow is
reversed by reversing the polarity of the applied electric current.
