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
