Titanium anode for electrodialysis

The titanium substrate offers excellent mechanical strength and chemical resistance. The anode surface is typically coated with precious metal oxides, such as ruthenium oxide (RuO₂), iridium oxide (IrO₂), or platinum (Pt), to enhance catalytic activity and prolong its life under harsh electrolysis conditions.

Electrodialysis (ED) utilizes an electric field to drive ion migration through a selective ion exchange membrane. The titanium anode plays a crucial role in ED, generating the necessary electric potential for ion migration.

Cations migrate toward the cathode, while anions migrate toward the anode through alternating cation and anion exchange membranes. Salts in some chambers are concentrated, while those in others are diluted. This process can selectively remove or recover specific ions from aqueous solutions.

Technical Parameters of Titanium Anode for Electrodialysis

Advantages of Using Titanium Anode for Electrodialysis
1. High Durability and Reliability

The robust structure of titanium combined with advanced oxide coatings provides exceptional resistance to wear and corrosion, even under continuous operation.

2. Environmental and Economic Benefits

Titanium anodes are environmentally friendly and recyclable. Their long life reduces maintenance frequency and replacement costs, improving overall process economy.

3. Superior Electrochemical Performance

The noble metal oxide coatings offer low oxygen overpotential and excellent catalytic activity, resulting in improved current efficiency and energy savings.

4. Consistent Product Quality

Uniform current distribution ensures stable ion migration, leading to consistent product quality in water treatment and industrial processing.

Applications of Titanium Anode in Electrodialysis Systems
1. Seawater and Brackish Water Desalination

Titanium anode for electrodialysis is widely used in desalination units to remove salts and produce fresh water. Its corrosion resistance and stable conductivity ensure consistent operation under high salinity and harsh environments.

2. Industrial Wastewater Treatment

In chemical, metallurgical, and pharmaceutical industries, electrodialysis systems equipped with titanium anodes are employed to separate heavy metals, recover valuable ions, and reduce total dissolved solids (TDS) in effluents.

3. Food and Beverage Industry

Electrodialysis technology helps in demineralization of whey, fruit juice, and other food solutions. Titanium anodes maintain high purity and prevent contamination due to their inert and stable surface.

4. Chemical Production and Ion Recovery

Titanium anodes are used in the recovery of acids, alkalis, and other ionic substances in electrochemical plants. Their stability allows for precise control of electrochemical reactions, improving product quality and yield.

5. Power and Energy Storage Fields

In emerging industries such as hydrogen production and battery recycling, titanium anode for electrodialysis contributes to efficient ion transport and selective ion separation processes, enhancing the sustainability of energy systems.

Titanium Anode for Electrodialysis Real-World Case：
1: Brackish Water Desalination in the Middle East

A large-scale electrodialysis desalination plant in the Middle East adopted titanium anodes with MMO coatings to handle high salinity and temperature conditions. After installation, energy consumption was reduced by 18%, and the electrode life exceeded five years without noticeable degradation.

2: Electroplating Wastewater Recovery in China

A metal finishing factory in China replaced conventional lead anodes with titanium anodes for electrodialysis. The result was a 40% reduction in maintenance costs and an improvement in ion removal efficiency by 25%, significantly enhancing wastewater recycling capacity.

3: Food-Grade Ion Removal in Europe

In a European dairy processing plant, titanium anodes were used for lactic acid recovery and demineralization of whey. The system achieved stable ion separation while maintaining high product purity, meeting strict EU food safety standards.
