Titanium anode for printing and dyeing wastewater treatment

In the modern textile and dyeing industry, printing and dyeing wastewater treatment has become a major challenge due to the complexity and persistence of organic dyes and chemicals. Among the various treatment technologies available, the titanium anode for printing and dyeing wastewater treatment has emerged as one of the most efficient and environmentally friendly solutions. This innovative electrode material offers high corrosion resistance, long service life, and strong oxidizing capability, making it ideal for industrial-scale wastewater purification systems.

A titanium anode is an electrochemical component made from high-purity titanium substrate, coated with precious metal oxides such as ruthenium oxide (RuO₂), iridium oxide (IrO₂), or mixed metal oxide (MMO). When used in printing and dyeing wastewater treatment, the titanium anode serves as the positive electrode in an electrolysis system, generating powerful oxidants like hydroxyl radicals (•OH) and active chlorine species to degrade organic pollutants effectively.

Technical Specifications

Advantages of Titanium Anode for Printing and Dyeing Wastewater Treatment
1. High Efficiency in Dye Degradation

The titanium anode enables complete mineralization of organic dyes, removing color and reducing COD (Chemical Oxygen Demand) efficiently without the need for chemical reagents.

2. Long Service Life and Stability

Thanks to the strong adhesion of the MMO coating and the corrosion-resistant titanium substrate, the anode can operate continuously for over 5–10 years, depending on the application conditions.

3. Energy Saving and Low Maintenance

With low overpotential and high current efficiency, titanium anodes consume less energy and require minimal maintenance, making them cost-effective for long-term operation.

4. Environmental Sustainability

Unlike traditional chemical treatment methods, this process produces no secondary pollution or harmful sludge, promoting sustainable and green wastewater treatment.

Applications of Titanium Anode in Printing and Dyeing Wastewater Treatment
1. Textile and Dyeing Plants

The most common application is in textile dyeing effluent treatment, where titanium anodes decolorize wastewater containing azo dyes, reactive dyes, and sulfur dyes.

2. Electrochemical Advanced Oxidation (EAOP) Systems

Titanium anodes are key components in EAOP systems, which combine electrolysis and oxidation to degrade persistent organic pollutants efficiently.

3. Decolorization and COD Reduction Units

They are used for color removal and COD reduction, meeting strict environmental discharge standards set by national and international agencies.

4. Zero Liquid Discharge (ZLD) Processes

Titanium anodes support ZLD technologies, allowing factories to recycle and reuse treated water, thus reducing overall water consumption and improving sustainability.

Successful Application in a Dyeing Factory Case: 

A textile factory in Southeast Asia adopted a titanium anode wastewater treatment system to replace its conventional Fenton oxidation process.

System Parameters: Current density of 50 A/m², operating temperature 30°C

Results:

Color removal rate: >95%

COD reduction: >85%

Operating cost reduced by 30%

Maintenance cycle extended to 18 months

This case demonstrates the reliability and cost-effectiveness of titanium anode technology for large-scale printing and dyeing wastewater treatment.
