Advanced Electrochemical Solutions for Industrial Wastewater Treatment

Titanium anodes for wastewater treatment offer a modern environmental engineering solution for the efficient, stable, and environmentally friendly treatment of industrial and municipal wastewater. With increasingly stringent emission regulations across industries, the demand for high-performance electrochemical systems continues to grow.

This technology utilizes titanium-based anodes coated with catalytic materials such as mixed metal oxides (MMOs) or platinum to achieve efficient oxidation of pollutants. Titanium anode technology for wastewater treatment ensures high degradation efficiency for organic pollutants, ammonia nitrogen, and recalcitrant compounds.

Structural Composition of Titanium Anodes for Wastewater Treatment

1: Advantages of the Titanium Substrate

The foundation of titanium anodes for wastewater treatment lies in high-purity titanium substrates (Grade 1 or 2), offering corrosion resistance, mechanical strength, and long-term stability.

2: Catalytic Coating Systems

Advanced coatings, such as:

Iridium Oxide (IrO₂)

Ruthenium Oxide (RuO₂)

Platinum (Pt)

These coatings improve oxygen evolution efficiency and reduce energy consumption.

Manufacturing Process of Titanium Anode Technology for Wastewater Treatment

1: Surface Pretreatment

The titanium surface undergoes sandblasting, acid washing, and ultrasonic cleaning to ensure coating adhesion.

2: Thermal Decomposition Coating

Thermal decomposition is used in titanium anodes for wastewater treatment to prepare a uniform metal oxide (MMO) coating, ensuring coating durability and catalytic efficiency.

3: Sintering and Activation

Multiple sintering cycles at controlled temperatures improve coating stability and extend electrode life.
