In EDR, the soil is placed in a desalination compartment instead of the normal electrolyte
solution to be desalted in conventional electrodialysis. After the remediation, the
heavy metals that were removed as cations and anions will be found concentrated in the
catholyte and in the anolyte, respectively. Depending on the actual heavy metal, different
methods can be used for separation of the heavy metals from the solution and make reuse
possible [9]. One method for separation and reuse of Cu, Hg, Cd, Zn, and Pb is electrodeposition.
