EDR desalination is an electrodialysis reversal 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 applied electric current.
