🔷 Product Overview
Titanium Anode for Seawater Electrolysis is a high-performance electrochemical electrode specifically engineered for operation in aggressive marine environments. By combining a titanium substrate with a ruthenium-iridium (Ru-Ir) mixed metal oxide coating, this anode provides excellent catalytic efficiency, long service life, and exceptional resistance to corrosion caused by seawater.
Seawater electrolysis is widely used in offshore and coastal industries for chlorine generation, anti-fouling, and water treatment. The titanium anode plays a critical role in converting chloride ions into active chlorine species, which effectively prevent biofouling and microbial growth in pipelines, cooling systems, and marine structures.
Compared to conventional electrode materials such as graphite or lead alloys, titanium anodes offer superior dimensional stability, lower energy consumption, and significantly reduced maintenance requirements.
🔷 Working Principle of Seawater Electrolysis
Schematic Diagram
The seawater electrolysis process is based on the electrochemical conversion of chloride ions naturally present in seawater. When electrical current is applied:
- At the anode: chloride ions (Cl⁻) are oxidized to chlorine gas (Cl₂)
- Chlorine reacts with water to form hypochlorous acid (HOCl)
- Hypochlorous acid acts as a powerful disinfectant and anti-fouling agent
This process enables continuous, on-site chlorine generation without the need for chemical storage or transportation, making it safer and more cost-effective for industrial use.
🔷 Key Advantages of Titanium Anode for Seawater Electrolysis
✅ 1. Superior Corrosion Resistance
Seawater contains high concentrations of salts and aggressive ions. The titanium substrate combined with Ru-Ir coating ensures excellent resistance against corrosion, even under high current density conditions.
✅ 2. Long Operational Lifetime
The advanced MMO coating technology provides stable electrochemical performance over extended periods, typically achieving 3–6 years of service life depending on operating conditions.
✅ 3. High Electrochemical Efficiency
The optimized catalytic surface reduces overpotential, improving chlorine generation efficiency while lowering energy consumption.
✅ 4. Strong Anti-Fouling Capability
Continuous chlorine production prevents marine organism growth such as algae, barnacles, and biofilms, ensuring system cleanliness and efficiency.
✅ 5. Dimensional Stability
Unlike graphite electrodes, titanium anodes maintain their structural integrity and do not deform or degrade over time.
✅ 6. Low Maintenance Requirements
The long lifespan and stable performance significantly reduce maintenance frequency and operational downtime.
✅ 7. Environmentally Friendly Solution
On-site electrolysis eliminates the need for transporting hazardous chlorine gas, improving safety and environmental compliance.
