Titanium anode for electrolytic sterilization and disinfection

Technical Parameters

How Does the Titanium Anode Work in Electrolytic Sterilization?

When current passes through the titanium anode for electrolytic sterilization and disinfection, water molecules and ions undergo oxidation and reduction reactions:

• At the anode:
  2Cl−→Cl2+2e−2Cl^- \rightarrow Cl_2 + 2e^-2Cl−→Cl2​+2e−
  H2O→O2+4H++4e−H_2O \rightarrow O_2 + 4H^+ + 4e^-H2​O→O2​+4H++4e−

• At the cathode:
  2H++2e−→H22H^+ + 2e^- \rightarrow H_22H++2e−→H2​

The generated chlorine (Cl₂), hypochlorous acid (HClO), and hydroxyl radicals (·OH) are powerful oxidants that destroy microbial cell membranes, oxidize organic matter, and inhibit biofilm formation. This process ensures continuous and efficient sterilization even in challenging water conditions.

Advantages of Electrolytic Sterilization

• No chemical addition: Only electricity and water are required.

• On-site generation: Disinfectants are produced instantly and locally.

• Environmentally friendly: No harmful residuals or by-products.

• Low maintenance: Long lifespan of the titanium anode ensures cost savings.

• Broad-spectrum efficacy: Effective against bacteria, viruses, and fungi.

Titanium Anode for Electrolytic Sterilization and Disinfection Benefits
1. Long Service Life

Thanks to the robust titanium base and stable oxide coating, the anode can operate over 8000–15000 hours in sterilization systems, depending on the current density and electrolyte composition.

2. High Current Efficiency

The surface coating ensures low overpotential for chlorine and oxygen evolution, providing high current efficiency (>90%) and reducing energy consumption.

3. Excellent Corrosion Resistance

The titanium anode for electrolytic sterilization and disinfection performs reliably in acidic, neutral, or saline environments without corrosion, scaling, or degradation.

4. Customizable Design

Manufacturers can tailor anode shapes—such as mesh, plate, tubular, or rod structures—based on reactor size, flow rate, and sterilization system design.

5 Eco-Friendly Operation

By eliminating chemical disinfectants, the titanium anode helps users meet environmental compliance regulations and reduce chlorine transportation risks.

Titanium Anode for Electrolytic Sterilization and Disinfection Industrial Applications
1. Drinking Water Treatment

Municipal and domestic water systems use titanium anodes for electrolytic sterilization and disinfection to produce safe, bacteria-free water without adding harmful chemicals. The process ensures continuous disinfection in water storage tanks and pipelines.

2. Swimming Pools and Spas

Replacing liquid chlorine, these anodes generate hypochlorous acid (HClO) directly in water, maintaining stable free chlorine concentration and preventing eye or skin irritation for swimmers.

3. Aquaculture and Fisheries

Fish farms use electrolytic sterilization to prevent bacterial infections and algae growth, ensuring a healthy aquatic environment without antibiotic residues.

4. Food and Beverage Industry

Used in CIP (Clean-in-Place) systems, titanium anodes help sterilize production lines, pipes, and storage tanks, ensuring hygienic operations and extending product shelf life.

5. Medical and Pharmaceutical Wastewater

Hospitals and labs use titanium anodes to oxidize pathogens and organic pollutants, reducing biological oxygen demand (BOD) and ensuring wastewater meets discharge standards.
Case Studies
1: Municipal Water Sterilization Project

A Southeast Asian water plant adopted titanium anodes for electrolytic sterilization and disinfection to replace traditional chlorination. The system now operates with 30% lower energy consumption and eliminates the need for bulk chlorine storage.

2: Aquaculture in the Middle East

In marine shrimp farms, titanium anodes generate on-site oxidants to control bacteria and algae. Farmers reported a 20% increase in survival rate and improved water clarity within 30 days of installation.

3: Medical Wastewater Treatment in Europe

A hospital implemented an electrolytic sterilization unit using RuO₂–IrO₂-coated titanium anodes. The result was complete inactivation of E. coli and Staphylococcus aureus, achieving EU wastewater standards.
