Electrodialysis is to
place water in direct current field to make
ions in water in make directional migration
and use the selective permeability of ion
exchange film for positive and negative ions
to make ions migrate to the effect of
separation between ions and water. It is
used before ion exchange system as a means
for pre-desalination and can extend the
regeneration cycle of the ion exchange
system. The device features low power
consumption, big output, high desalination
rate and high stability. |
