Titanium anodes for wastewater treatment

Titanium anodes for wastewater treatment are electrochemical electrodes made primarily from high-purity titanium substrates coated with active catalytic materials such as ruthenium oxide (RuO₂), iridium oxide (IrO₂), or mixed metal oxides (MMO). These coatings enhance the electrode’s conductivity, corrosion resistance, and catalytic activity, making titanium anodes a cornerstone in modern wastewater purification systems.

In wastewater treatment, titanium anodes act as the driving force behind electrochemical oxidation processes that break down organic pollutants, oxidize heavy metals, and disinfect harmful microorganisms. Their durability, efficiency, and eco-friendly operation make them an indispensable part of industrial and municipal water treatment facilities worldwide.

Technical Specifications

Technical Advantages of Titanium Anodes for Wastewater Treatment
1. Long Service Life

Titanium anodes can last up to 10–15 years under normal operating conditions, significantly reducing maintenance costs and downtime.

2. High Current Efficiency

The advanced catalytic coating ensures efficient electron transfer, resulting in lower energy consumption and higher oxidation rates.

3. Adjustable Structure and Custom Design

Titanium anodes can be fabricated in various shapes—plate, mesh, tube, or rod—to match different reactor designs and operating conditions.

4. Wide Operating Range

They perform reliably across a broad pH range (1–12) and temperature conditions, offering great flexibility for industrial applications.

Applications of Titanium Anodes for Wastewater Treatment
1. Industrial Wastewater Treatment

Titanium anodes are used extensively in industries such as:

Electroplating (removal of cyanides, chromium, and nickel ions)

Petrochemical (degradation of hydrocarbons and phenols)

Textile (oxidation of dyes and surfactants)

Pharmaceutical (elimination of refractory organic compounds)

By utilizing electrochemical oxidation, titanium anodes decompose complex organic molecules into simpler, harmless compounds like CO₂ and H₂O.

2. Municipal Wastewater Treatment

Municipal facilities use titanium anodes for disinfecting sewage and reducing biological oxygen demand (BOD) and chemical oxygen demand (COD) levels. This results in cleaner, safer water suitable for discharge or reuse.

3. Landfill Leachate Treatment

Titanium anodes for wastewater treatment are also highly effective in breaking down ammonia nitrogen and organic pollutants found in landfill leachate, which is known for its high toxicity and complex composition.

4. Reuse and Recycling Applications

In water recycling systems, titanium anodes assist in advanced oxidation processes to regenerate treated water for industrial reuse—promoting sustainability and resource conservation.

Successful Applications of Titanium Anodes Case: 
1: Electroplating Wastewater Treatment

A large electroplating facility adopted MMO-coated titanium anodes to treat wastewater containing hexavalent chromium and heavy metals. The electrochemical oxidation process achieved over 95% chromium removal while reducing COD by 80%. The system has operated continuously for more than 8 years with minimal maintenance.

2: Pharmaceutical Industry

A pharmaceutical company used titanium anodes to decompose antibiotic residues in wastewater. The treatment reduced persistent organic pollutants and met stringent environmental discharge standards without chemical additives.

3: Landfill Leachate Treatment

In a municipal landfill project, titanium anodes were used for electrochemical oxidation of leachate containing ammonia nitrogen and phenolic compounds. The process improved biodegradability, allowing integration with biological treatment systems for complete purification.
