Titanium anode for electrolyzing salt water

A titanium anode for electrolyzing salt water is a specially designed electrode made of a titanium substrate coated with precious metal oxides such as ruthenium (RuO₂), iridium (IrO₂), or mixed metal oxides (MMO). Its primary function is to conduct current and catalyze the electrolytic decomposition of sodium chloride (NaCl) in brine or seawater, producing chlorine gas, hydrogen, and sodium hydroxide.

The general electrolysis reaction is:

Here, the titanium anode serves as the oxidation electrode, promoting the evolution of chlorine gas while resisting severe corrosion from chloride ions and high voltage.

Technical Parameters of Titanium Anode for Electrolyzing Salt Water

These parameters can be customized based on the client’s specific operating environment and electrochemical requirements.

Key Features and Advantages of Titanium Anode for Electrolyzing Salt Water
1. Excellent Corrosion Resistance

Titanium itself forms a passive oxide film, while the noble metal oxide coating further enhances its resistance to chlorine and alkaline environments, ensuring long service life even in harsh seawater.

2. High Electrochemical Efficiency

The catalytic coating provides low overpotential for chlorine evolution, significantly reducing power consumption during electrolysis and improving operational efficiency.

3. Long Service Life

Thanks to stable coating structures, the titanium anode for electrolyzing salt water can maintain performance for over 5–10 years depending on usage conditions, minimizing replacement costs and downtime.

4. Uniform Current Distribution

The precisely engineered coating ensures even current flow and chlorine generation across the anode surface, which is critical for process stability in large-scale electrolysis systems.

5. Environmental and Economic Benefits

Unlike graphite or lead-based electrodes, titanium anodes produce no toxic byproducts, making them environmentally friendly and suitable for sustainable industrial production.

Applications of Titanium Anode for Electrolyzing Salt Water

1. Chlor-Alkali Industry

The titanium anode for electrolyzing salt water is the heart of chlor-alkali plants producing chlorine (Cl₂), hydrogen (H₂), and sodium hydroxide (NaOH). Its stable chlorine evolution potential ensures efficient production with reduced energy consumption.

2. Seawater Electrolysis and Desalination

In seawater treatment plants, titanium anodes are used to generate chlorine for biological sterilization and anti-fouling of pipelines and membranes. Their long lifespan and chemical stability make them ideal for continuous marine operations.

3. Electrolyzed Water Generators

Electrolyzed water systems used for disinfection in food processing, hospitals, and swimming pools rely on titanium anodes to produce hypochlorous acid (HOCl) safely and efficiently.

4. Wastewater Treatment

Titanium anodes are employed in electrochemical oxidation systems to decompose organic pollutants, cyanides, and ammonia nitrogen compounds. They help achieve high-efficiency oxidation without additional chemicals.

5. Cathodic Protection and Marine Engineering

Titanium anodes coated with MMO are also applied in cathodic protection systems for ships, offshore platforms, and seawater pipelines, preventing corrosion and extending equipment lifespan.

Industrial Applications of Titanium Anodes Case:
1. Seawater Chlorination System in Coastal Power Plant

A coastal thermal power plant adopted titanium anodes for its seawater electrolysis system to prevent biofouling in cooling pipelines. After installation, the plant achieved stable chlorine generation efficiency above 90% and reduced maintenance frequency by 50%.

2. Wastewater Treatment Plant for Textile Industry

In an electrochemical oxidation setup, titanium anodes helped break down dye molecules, achieving color removal efficiency above 95% and COD reduction of 80%, demonstrating excellent performance in organic wastewater treatment.

3. Electrolyzed Water Disinfection System

Food processing factories use titanium anodes to generate hypochlorous acid for surface and equipment disinfection, providing a safe, chemical-free sanitation solution that meets food safety standards.
