Titanium anode for ammonia nitrogen wastewater treatment

A titanium anode is a conductive electrode made from a titanium substrate coated with precious metal oxides such as ruthenium (RuO₂), iridium (IrO₂), or platinum (Pt). When applied in ammonia nitrogen wastewater treatment, it serves as the anode in an electrochemical oxidation system, converting ammonia nitrogen (NH₃-N) into harmless nitrogen gas (N₂) or nitrate (NO₃⁻) through controlled redox reactions.Technical Specifications。

Technical Parameters of Titanium Anode for Ammonia Nitrogen Wastewater Treatment

Advantages of Titanium Anode in Ammonia Nitrogen Wastewater Treatment
1. High Efficiency and Selectivity

The unique oxide coating structure provides strong catalytic activity, ensuring rapid conversion of ammonia nitrogen into nitrogen gas with minimal byproducts.

2. Excellent Corrosion Resistance

Titanium’s passive oxide film combined with noble metal coatings guarantees exceptional resistance to corrosion in acidic, alkaline, or chloride-rich environments.

3. Long Service Life

Compared to graphite or lead anodes, titanium anodes offer significantly longer service life — often exceeding 5–10 years under proper operating conditions.

4. Low Energy Consumption

Due to low overpotential for oxygen and chlorine evolution reactions, titanium anodes minimize energy use in electrochemical oxidation systems.

5. Environmentally Friendly

No harmful chemical additives are required. The process produces minimal sludge and reduces secondary pollution risks, aligning with green manufacturing principles.

Applications of Titanium Anode for Ammonia Nitrogen Wastewater Treatment
1. Chemical and Petrochemical Industries

Ammonia-rich effluents from fertilizer, resin, and dye production can be efficiently treated using titanium anodes, achieving >95% ammonia nitrogen removal without secondary pollution.

2. Electroplating and Metal Finishing Plants

Electroplating rinse water often contains cyanides, ammonia, and organic contaminants. The titanium anode system oxidizes these compounds effectively, ensuring compliance with environmental discharge standards.

3. Semiconductor and Electronics Manufacturing

Wastewater from etching and cleaning processes contains high levels of ammonium ions and complex organic compounds. Titanium anodes are ideal for such high-tech wastewater treatment, maintaining stable operation under variable loads.

4. Landfill Leachate Treatment

Leachate is typically high in ammonia nitrogen and refractory organics. Electrochemical oxidation with titanium anodes helps achieve deep purification before biological treatment or discharge.

Titanium Anode Application in Ammonia Nitrogen Wastewater Treatment Case:

A chemical fertilizer factory in Southeast Asia implemented an electrochemical oxidation system using RuO₂–IrO₂ coated titanium anodes.
Results:

Influent ammonia nitrogen concentration: 180 mg/L

Effluent ammonia nitrogen: <5 mg/L

Removal efficiency: >97%

Energy consumption: 2.1 kWh/m³

Continuous operation life: 3+ years without significant performance decay

This demonstrates the outstanding stability and cost-effectiveness of titanium anodes in real-world industrial wastewater treatment.
