Description
The seawater electrochlorination titanium anode is an essential electrode component used in marine disinfection, desalination pretreatment, offshore water systems, and industrial cooling water treatment. It is designed to generate chlorine directly from natural seawater through an electrochemical process, providing a safe and reliable solution for biofouling control, pipeline protection, and continuous water disinfection.
In seawater treatment systems, biological growth is one of the most common operational problems. Algae, bacteria, microorganisms, barnacles, and mussels can attach to pipelines, heat exchangers, seawater intake systems, and reverse osmosis pretreatment equipment. Over time, this fouling may reduce water flow, increase maintenance costs, and affect the long-term stability of the system. A high-quality seawater electrochlorination titanium anode helps solve this problem by enabling on-site chlorine generation without the need for storing or transporting hazardous chemical disinfectants.
⚙️ Working Principle
Seawater naturally contains chloride ions. During electrochlorination, the titanium anode oxidizes chloride ions and generates chlorine. The chlorine then reacts with water to form sodium hypochlorite, which works as an effective disinfectant. This process is widely used in seawater desalination plants, offshore platforms, ships, power plants, and marine cooling water systems.
The seawater electrochlorination titanium anode is usually made from Grade 1 or Grade 2 titanium substrate and coated with mixed metal oxide coating, such as Ru-Ir or Ir-Ta coating. This coating provides strong electrocatalytic activity, high current efficiency, and excellent resistance to chloride-rich environments.

🛡️ Key Advantages
⚙️ High Chlorine Generation Efficiency
The advanced MMO coating allows efficient chlorine production with stable electrochemical performance. Under proper operating conditions, chlorine current efficiency can reach more than 95%, helping reduce power consumption and improve system output.
⏱️ Long Service Life
A properly designed seawater electrochlorination titanium anode can achieve a service life of 3–7 years, depending on current density, water quality, operating temperature, and maintenance conditions.
🛡️ Excellent Corrosion Resistance
Seawater is highly corrosive because of its high chloride concentration. Titanium substrate combined with MMO coating provides strong corrosion resistance, making the anode suitable for long-term marine operation.
📊 Stable Current Performance
The anode can typically operate under a current density range of 200–1000 A/m². This makes it suitable for different electrochlorination systems, from compact units to large industrial installations.
🔧 Custom Design Support
The seawater electrochlorination titanium anode can be manufactured as plate, mesh, rod, tube, or customized shapes according to the customer’s equipment design.

These technical parameters can be adjusted according to system requirements. For example, higher coating loading is usually recommended for systems with higher current density or longer continuous operation time. For seawater systems with strong fouling risk, a stable and durable seawater electrochlorination titanium anode is especially important.
🌊 Applications in Seawater Desalination
In desalination plants, seawater pretreatment is critical before the reverse osmosis process. If microorganisms enter the system without proper control, they may cause membrane fouling, higher pressure drop, lower water production efficiency, and more frequent chemical cleaning.
The seawater electrochlorination titanium anode is used to generate sodium hypochlorite on-site, helping disinfect seawater intake pipelines, pretreatment tanks, filters, and related equipment. This improves system cleanliness and supports stable operation of the desalination plant.
Compared with direct chemical dosing, electrochlorination reduces chemical storage risks and improves operational safety. It is especially useful for remote areas, islands, offshore platforms, and large marine water treatment projects.
🏭 Manufacturing Quality
The performance of a seawater electrochlorination titanium anode depends heavily on substrate preparation, coating formula, coating thickness, sintering process, and final inspection. Before coating, the titanium surface should be properly treated to improve coating adhesion. After coating, the anode should be tested to ensure stable electrochemical activity and uniform surface quality.
Our titanium anodes are produced with strict quality control. The process includes material inspection, surface treatment, coating preparation, thermal decomposition, dimensional inspection, and electrochemical testing. This ensures that each anode can provide reliable performance in seawater electrochlorination systems.
