Electrodialysis Laboratory Equipment


‌Overview of Electrodialysis Laboratory Equipment





Electrodialysis laboratory equipment is an experimental device designed to separate liquids and remove ions based on the principle of electrodialysis. It utilizes the selective ion permeability of ion-exchange membranes under an electric field to separate and purify dissolved salts or other charged substances from aqueous solutions. Electrodialysis technology finds applications in fields such as water treatment, seawater desalination, wastewater treatment, chemicals, and the food industry. Laboratory-scale electrodialysis equipment is used to study the feasibility of electrodialysis processes and optimize parameters.



Working Principle



The key principle of electrodialysis equipment is ion migration driven by an electric field. Under the influence of the electric field, cations move toward the cathode and anions move toward the anode. Selective anion-exchange and cation-exchange membranes allow specific ions to pass through while others are retained. Through a multi-stage membrane stack structure, the equipment concentrates or removes salts or other charged substances from water, resulting in a purified solution.
