Titanium Anode Mesh for Electrodialysis
1.Product Introduction:
The Titanium Anode Mesh for Electrodialysis plays a vital role in the process of separating, concentrating, and purifying ions from water. Under the influence of an external DC electric field, cation and anion exchange membranes selectively allow ions to pass through. Cations migrate through the cation membrane towards the cathode solution, while anions move through the anion membrane towards the anode solution. This ion movement helps achieve the desired concentration, purification, and separation of substances in water.
In electrodialysis systems, ions selectively transfer from one solution to another, helping separate and concentrate ionized pollutants.
2.Available Forms:
- Shapes: The Titanium Anode for Electrodialysis is available in various forms, including plates, meshes, and customized special shapes to suit different applications.
3.Applications:
- Continuous Electrode ionization (EDI) for producing ultrapure water
- Electrodialysis Reactors (ED/EDR) for material separation and the concentration of high-salt wastewater
- Seawater and Brackish Water Desalination
- Industrial Wastewater Treatment through electrodialysis
4.Electrode Requirements:
In electrodialysis desalinates, besides the ion exchange membranes, the electrode is a critical component. Particularly during frequent polarity reversals, the electrode must be resistant to both oxidation and reduction, functioning as both an anode and cathode. Common electrode materials, such as graphite, may fail to meet these requirements due to corrosion, leading to a reduced service life.
5.Advantages of Titanium-Based Anode:
The titanium-based noble metal oxide-coated anode is considered ideal for electrodialysis due to its ability to handle polarity reversals without degradation. It also offers:
- Low chlorine evolution overpotential
- Superior energy-saving performance
- Long service life
This innovative electrode solution helps enhance the efficiency and durability of electrodialysis processes in various industries.
