Descripción del producto

Electrodialysis refers to the directed migration of ions in a solution under the action of a direct current electric field, selectively passing through an ion exchange membrane and removing charged ions from the solution. A physicochemical process that separates solute from water by using the potential difference as a driving force and utilizing the selective permeability of the anion and cation exchange membranes to the anion and the cation. It can realize the desalination of brackish water or seawater, salt concentration, desalting and refining of organic solution.
In electrodialysis, there are a cation exchange membrane that allows only cations to pass through and an anion exchange membrane that allows only anions to pass through, and the two ion exchange membranes are alternately arranged to constitute a desalination chamber and a concentration chamber. The electrodialysis membrane assembly is composed of a main component such as a separator, an ion exchange membrane, an electrode, and a clamping device.

Characteristics of Electrodialysis Membrane Stack

• High selectivity to the separated components;
• low energy consumption and low engineering investment;
• continuous operation, high degree of automation;
• The concentration of salt is higher and the water recovery rate is higher;
• not changing the properties of the solution due to chemical action and thermal degradation;
• No regeneration is required, no chemicals are required, and the pretreatment requirements are low.
