Electrode Technology for Electrodialysis Desalination
Electrodialysis is a highly efficient desalination method that enables continuous freshwater production through ion-selective membrane systems under electrical driving force.
Compared with traditional methods (distillation, freezing, reverse osmosis), electrodialysis offers:
Lower energy consumption
Continuous operation
Compact system design
High operational efficiency
Engineering Challenges & Solution
In electrodialysis systems, electrodes must withstand alternating oxidation and reduction conditions. Conventional materials such as graphite suffer from rapid corrosion and limited lifespan.
Our titanium-based mixed metal oxide electrodes overcome these limitations by providing:
Bidirectional electrochemical stability
Low overpotential operation
Excellent resistance to chemical attack
Long-term structural integrity
Key Advantages
High Energy Efficiency
Low overpotential coating significantly reduces power consumption in continuous operation systems.
Exceptional Corrosion Resistance
Stable performance in aggressive seawater and electrolyte environments.
Recoatable Design
Deactivated coating layers can be renewed, extending service life and reducing replacement cost.
Long Service Life
Engineered for multi-year continuous industrial operation with stable electrochemical performance.
Structural Flexibility
Can be manufactured into complex geometries including plates, meshes, and custom electrode assemblies.
