11. Strategic partners:

12. Definition of Electrodialysis
Electrodialysis (ED) is an electrically-driven method of removing dissolved ionic compounds
Dissolved solids may exist in a form of ions that are either positively or negatively charged (cations or anions)
When an electrical potential is applied across the ion-selective membrane, cations migrate towards the negative electrode (cathode) and anions migrate towards positive electrode (anode)
The driving force is DC electric field

13. Definition and Characteristics of Ions
Ions are nothing more than atoms or molecules that have gained or lost an electron(s).
Generated by salts, acids or alkalies dissociation in water
Both types – organic and inorganic
Independent movement in solution
Cation is a positively charged (loosing of electron) ion
Cations migrate to the cathode
Anion is a negatively charged (gaining of electron) ion
Anions migrate to the anode

14. Ion-exchange Membranes
Ion-exchange membranes present ion-selective barries
Cation-exchange membranes (CM)
Selective transport of cations
Anionic transport blocked
Permselectivity about 96 %
Anion-exchange membranes (AM)
Selective transport of anions
Cationic transport blocked

15. Electrodialyzer – Heart of the ED Process
Basic characteristics
Series of alternating ion-exchange membranes separated by spacers
One cation and one anion exchange membrane plus two spacers = cell pair
Spacers are alternately connected to internal manifolds for proper liquids distribution
Platinum-coated titanium electrodes
