What Is a Titanium Mesh Anode?
Mesh-type titanium anodes are a new type of insoluble anode material fabricated from high-purity industrial titanium (Gr1/Gr2) as the substrate, coated with noble metal oxide catalytic layers such as ruthenium-iridium.
Unlike conventional plate electrodes, the mesh structure delivers superior mass transfer efficiency and current distribution characteristics in electrochemical water treatment processes, making it particularly suitable for the electrolytic oxidation treatment of recalcitrant organic wastewater.
What Are the Key Advantages of Titanium Mesh Anodes?
Enhanced Performance Through Mesh Structure
The porous mesh structure increases the active surface area, improves electrolyte flow and mass transfer, and accelerates electrochemical oxidation while reducing the limitations of flat plate electrodes.
Flexible Customization
Dimensions, shape, mesh opening, plate size, mounting holes, and substrate thickness (0.9–2 mm) can be customized. Diamond-shaped and perforated mesh options are available for different reactor designs.
Mature Ru-Ir Coating System
Ru-Ir coating provides efficient electrolysis at low cell voltage, with a chlorine evolution potential of ≤1.13 V and an oxygen evolution potential of ≤1.6 V.
Wide Compatibility
Flexible specifications and configurations allow the titanium mesh anodes to fit various electrolytic equipment and wastewater treatment applications.

Why Choose Our Titanium Mesh Anodes?
Reusable Titanium Substrate
After the anode reaches the end of its service life, the precious metal coating can be removed and recoated, allowing the titanium substrate to be reused and reducing long-term operating costs.
Stable and Controlled Quality
From titanium mesh forming, annealing, and sandblasting to coating sintering, every production step is controlled in-house. Electrochemical performance and coating adhesion are tested before shipment to ensure consistent quality from batch to batch.
Application-Specific Customization
Based on the electrolytic cell dimensions, wastewater characteristics, current density, and other operating conditions, we provide recommendations for anode structure and coating loading. Small-scale trial samples are also available for testing and validation.
FAQ
How do I select the right titanium mesh anode for wastewater treatment?
The anode should be selected based on the wastewater composition, target pollutants, required treatment capacity, operating current, current density, pH, temperature, electrode spacing, and reactor design. Mesh opening and MMO coating composition should also be considered to achieve the required mass transfer, electrochemical performance, and service life.
What MMO coating is suitable for wastewater treatment?
The coating should be selected according to the dominant electrochemical reaction. Ru-Ir MMO coatings are commonly used for chlorine evolution and indirect oxidation in chloride-containing wastewater, while Ir-based coatings such as Ir-Ta are more suitable for oxygen-evolution and direct electrochemical oxidation applications. Custom coating formulations can be developed for specific wastewater conditions.
How does mesh opening affect wastewater treatment performance?
Mesh opening affects the balance between active surface area, electrolyte flow, mass transfer, and resistance to clogging. Smaller openings can provide a larger electrochemically active area, but may be more susceptible to suspended solids. Larger openings can improve flow and reduce clogging in wastewater with higher solids content. The optimal mesh size should therefore be selected according to the actual wastewater and reactor conditions.
What current density should be used for a titanium mesh anode?
There is no universal current density for all wastewater applications. The appropriate value depends on the pollutant type, wastewater conductivity, electrode coating, temperature, pH, target reaction, and reactor configuration. Current density should be determined together with the required anode area to balance treatment efficiency, energy consumption, and coating life.
