Strategic partners:

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

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

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

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
