Sodium Chloride Electrolyzer with Titanium Anode
Updated : May. 22, 2026On-site sodium hypochlorite generation via sodium chloride electrolysis provides a stable and reliable chlorine supply for water treatment and disinfection systems. Compared to traditional chlorine gas or chemical dosing, it reduces safety risks and operating costs, making it ideal for long-term continuous operation in municipal and industrial water systems.
Leveraging advanced titanium anode electrolysis, we offer a complete solution including anode components and system configurations. High-performance MMO-coated anodes and optimized designs deliver higher efficiency, longer service life, and stable chlorine output. Equipment and anode configurations can be tailored to project scale and operating conditions, ensuring reliable long-term performance while minimizing maintenance and overall operational expenses.
Principle and Advantages of Sodium Chloride Electrolysis for Chlorine Production
Sodium chloride electrolyzers prepare sodium hypochlorite solution on-site by electrolyzing low-concentration brine (approximately 2%–5%). During electrolysis, the electrochemical reaction occurs on the surface of the titanium anode, generating a sodium hypochlorite disinfectant with strong oxidizing properties, which is widely used in water treatment and industrial wastewater treatment systems.
In practical applications, the equipment demonstrates significant advantages in terms of efficiency, stability, and operating costs:
- Multi-structure electrolyzer design to adapt to different production capacity requirements
- MMO titanium anodes improve electrolysis efficiency and extend service life.
- Low salt and low energy consumption operation reduces overall costs.
- The transparent electrolytic cell structure allows for clear visualization of its operating status.
- Optimize the conductive structure to improve current utilization and stability.
- Supports electrode refurbishment and maintenance, reducing long-term operating costs.
System Structure & Main Components of a Sodium Chloride Electrolyzer
The sodium chloride electrolytic cell system mainly consists of the electrolytic cell body, power supply system and titanium anode components. Through modular structural design, it achieves stable electrolysis operation and flexible configuration, and is suitable for different chlorine production scales and application scenarios.
- Electrolyzer body: As the core reaction unit, it is used to carry out the brine electrolysis process. Its structural design directly affects the electrolysis efficiency and system stability.
- Power supply system: Provides a stable DC power input to ensure continuous operation of the electrolysis process and optimize energy consumption.
- Titanium anode assembly: As a key reaction component, it adopts coating systems such as MMO to achieve efficient chlorine evolution and long-term stable operation.
We not only provide standardized electrolysis equipment, but also support flexible configuration according to capacity and operating conditions, providing a foundation for subsequent equipment selection and system matching.
