10. Main Products & Applications
11. Strategicpartners:
12. DefinitionofElectrodialysis 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 CharacteristicsofIons 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-exchangemembranespresent ion-selectivebarries Cation-exchange membranes (CM) Selective transport of cations Anionic transport blocked Permselectivityabout 96 % Anion-exchange membranes (AM) Selective transport of anions Cationic transport blocked Permselectivityabout 96 %
