High Efficiency Ru-Ir Coated Titanium Electrode for Industrial Chlorine Production
MMO Titanium Anode for Chlorine Generation is a high-performance dimensionally stable anode (DSA) specially designed for chlorine evolution applications in brine electrolysis systems. The electrode is manufactured using high-purity titanium substrate coated with ruthenium-iridium mixed metal oxide (Ru-Ir MMO), providing excellent electrocatalytic activity, superior corrosion resistance, low chlorine evolution overpotential, and long service life.
This MMO titanium anode is widely used in chlorine generation systems, sodium hypochlorite generators, seawater electrolysis equipment, electrochlorination systems, ballast water treatment units, industrial disinfection systems, cooling water treatment systems, and various electrochemical applications requiring efficient chlorine production.
Compared with graphite electrodes and traditional lead-based anodes, MMO Titanium Anode for Chlorine Generation offers significantly lower energy consumption, higher current efficiency, stable electrode dimensions, and improved operational reliability.
What Is Chlorine Generation?
Chlorine generation is an electrochemical process that produces chlorine or sodium hypochlorite from sodium chloride solution through electrolysis.
During electrolysis:
- chloride ions are oxidized at the anode,
- chlorine gas is generated,
- sodium hypochlorite can be formed in solution,
- hydrogen is produced at the cathode.
The performance of the anode directly affects:
- chlorine production efficiency,
- operating voltage,
- energy consumption,
- service life,
- system stability.
Ru-Ir coated MMO titanium anodes are among the most widely used electrodes for chlorine evolution due to their outstanding catalytic activity and resistance to chloride corrosion.
Advantages of MMO Titanium Anode for Chlorine Generation
Excellent Chlorine Evolution Performance
The Ru-Ir MMO coating has extremely high catalytic activity for chlorine evolution reaction (CER).
This enables:
- efficient chlorine generation,
- low electrolysis voltage,
- improved current efficiency,
- reduced power consumption.
The anode maintains stable chlorine production even under continuous industrial operation.
Outstanding Corrosion Resistance
The titanium substrate provides exceptional resistance to chloride-containing electrolytes, seawater, and harsh electrochemical environments.
The precious metal oxide coating protects the electrode surface and greatly extends service life.
Long Service Life
MMO Titanium Anode for Chlorine Generation can operate continuously for years under proper working conditions.
Compared with graphite anodes:
- no rapid consumption,
- no contamination,
- lower maintenance frequency,
- longer replacement intervals.
Typical service life can reach:
- 3–5 years,
- 5–7 years,
- or customized longer-life solutions.
Dimensionally Stable Electrode
The electrode is also known as a DSA (Dimensionally Stable Anode).
Unlike consumable graphite electrodes, the titanium substrate maintains stable geometry during electrolysis.
Benefits include:
- stable electrode spacing,
- stable operating voltage,
- consistent chlorine output,
- improved electrolysis efficiency.
Lower Operating Cost
Due to lower chlorine evolution overpotential, the MMO titanium anode reduces overall system power consumption.
This helps:
- reduce operating cost,
- improve energy efficiency,
