Electrodialysis is an electrically driven membrane separation
process that is capable of separating, concentrating, and purifying
selected ions from aqueous solutions (as well as some organic solvents).
The process is based on the property of ion exchange membranes to
selectively reject anions or cations. Electrodialysis can remove
salts from food, dairy, and other products, waste streams and other
solutions, as well as concentrate salts, acids or bases. The system
is a useful tool to remove unwanted total dissolved solids that
can build up in product streams.
