Titanium Anode for Brine Chlorination

Description

Custom quotation. Share your drawing, dimensions, quantity, electrolyte and operating conditions. The final configuration and quotation are confirmed for your application. Service life depends on operating conditions.

Selecting a Titanium Anode for a Brine Chlorination Cell

This product is a Ru-Ir MMO coated titanium electrode supplied to a confirmed drawing and operating duty. Identify the electrolyte and the intended process before selecting the electrode. Prepared salt brine and seawater applications should be reviewed separately; a matching electrode shape alone does not establish compatibility.

• Brine conditions: provide the sodium chloride concentration, water source, available water analysis, operating temperature and any known impurities or deposits.
• Electrical duty: provide the cell current, voltage, active electrode area where known, operating hours and any polarity reversal cycle required by the equipment.
• Cell geometry: send a drawing showing electrode dimensions, thickness, spacing, mounting points and electrical connections. State whether the enquiry is for a single electrode or an assembly.
• Replacement history: include the original electrode specification, photographs and the observed reason for replacement, such as coating wear, deposits or a connection problem.

The operating ranges in the specification table are reference information, not a promise that every combination is suitable. Confirm the coating, current density and service-life requirement together for the actual cell duty. The electrode specification alone does not define the chlorine output of a complete generator.

For a more specific application, see our titanium anode for sodium hypochlorite generation, seawater electrochlorination electrode or MMO titanium anode for chlorine generation. Confirm compatibility with your equipment rather than treating these applications as interchangeable.

Drawing, Inspection and Quotation Checklist

Include the drawing revision, quantity, delivery destination and required delivery date in your enquiry. Identify any material certificates, dimensional inspection records or coating inspection documents needed, and agree the scope and acceptance criteria in the quotation.

Can a replacement electrode be ordered from a photograph?

A photograph can help identify the assembly, but a quotation also needs dimensions, connection details and operating conditions. Send the original drawing where available and flag any measurements that still need confirmation.

Does the quotation include a complete chlorination system?

This page describes the electrode. List any additional components required and confirm whether the scope includes an electrode assembly, cell, power supply or controls.

How should the service-life requirement be specified?

State the required operating hours and the electrolyte, current and maintenance conditions associated with them. Confirm the proposed coating and any test or warranty terms in the quotation; a general lifetime figure is not a guarantee for every installation.

Industrial Ru-Ir MMO Titanium Anode for Efficient Brine Electrolysis Systems

Titanium Anode for Brine Chlorination is a high-performance mixed metal oxide (MMO) coated titanium electrode specially designed for brine electrolysis and chlorine generation systems. The anode uses high-purity Grade 1 titanium as the substrate and is coated with ruthenium-iridium precious metal oxides, providing excellent electrocatalytic activity, low chlorine evolution potential, outstanding corrosion resistance, and long service life in chloride-containing environments.

This type of titanium anode is widely used in sodium hypochlorite generators, seawater electrolysis systems, industrial chlorination equipment, ballast water treatment systems, cooling water disinfection systems, swimming pool chlorination equipment, and various electrochemical water treatment applications.

Compared with traditional graphite anodes and lead-based electrodes, the Titanium Anode for Brine Chlorination offers lower operating voltage, higher current efficiency, dimensional stability, lower maintenance costs, and significantly longer service life.

What Is Brine Chlorination?

Brine chlorination is an electrochemical process that converts sodium chloride solution (brine) into chlorine, sodium hypochlorite, and other oxidizing agents through electrolysis.

In the electrolysis process:

• The titanium anode generates chlorine gas
• The cathode produces hydrogen
• Sodium hypochlorite is formed in the solution

Because the anode continuously works under highly corrosive chloride conditions, the electrode material must have:

• Excellent chlorine evolution capability
• Strong corrosion resistance
• High conductivity
• Stable coating adhesion
• Long-term dimensional stability

Ru-Ir coated titanium anodes are considered one of the best solutions for brine chlorination systems.

Advantages of Titanium Anode for Brine Chlorination

Excellent Chlorine Evolution Efficiency

The Ru-Ir MMO coating provides very low chlorine evolution overpotential, allowing the system to generate chlorine efficiently while reducing energy consumption.

This improves:

• Electrolysis efficiency
• Chlorine output
• System stability
• Operating economy

---

Outstanding Corrosion Resistance

The titanium substrate has excellent resistance to chloride corrosion, seawater corrosion, and acidic environments.

The precious metal oxide coating protects the electrode surface from rapid degradation and ensures stable electrochemical performance.

---

Long Service Life

Compared with graphite electrodes, the Titanium Anode for Brine Chlorination can operate for several years under proper current density and electrolyte conditions.

Typical service life:

• 3–5 years
• 5–7 years
• Even longer for optimized systems

depending on operating conditions.

---

Dimensionally Stable Electrode

The MMO coated titanium anode is also called DSA (Dimensionally Stable Anode).

Unlike graphite anodes:

• the electrode does not dissolve rapidly,
• the electrode gap remains stable,
• the electrolysis voltage stays consistent.

This helps reduce energy consumption and maintenance frequency.

---

Lower Operating Voltage

The Ru-Ir coating significantly reduces cell voltage during electrolysis.

Benefits include:

• lower DC power consumption,
• reduced heat generation,
• improved system efficiency,
• lower operational costs.
