🟩 What is Titanium Anode for Water Treatment?

A titanium anode for water treatment is an electrochemical electrode manufactured using a titanium substrate coated with mixed metal oxides (MMO), such as iridium-tantalum or ruthenium-iridium coatings.

These anodes are designed to generate strong oxidizing agents during electrolysis, enabling effective removal of pollutants, bacteria, organic compounds, and heavy metal ions from water.

Titanium anodes are widely used in:

Industrial wastewater treatment
Municipal sewage treatment
Swimming pool disinfection
Cooling water systems
Drinking water sterilization
Seawater treatment

🟩 How Does Titanium Anode Work in Water Treatment?

During electrolysis, the titanium anode triggers oxidation reactions on the electrode surface.

Depending on the electrolyte composition, the anode can generate:

Hydroxyl radicals (•OH)
Active chlorine (Cl₂ / ClO⁻)
Oxygen (O₂)
Ozone (O₃) in special systems

These oxidants help break down:

Organic contaminants
Ammonia nitrogen
Color compounds
Bacteria and viruses
COD / BOD pollutants
