Product Introduction
The Electrochemical Degradation Titanium Anode is tailored for indirect oxidation of persistent COD compounds, particularly in textile, dyeing, and pharmaceutical wastewater. It features a high-OEP MMO coating that generates hydroxyl radicals efficiently with low voltage loss. Ideal for EAOP retrofits where lifetime, salt tolerance, and efficiency matter.

⚠ pH <5.0 will degrade coating within 48 hours.
⚠ >30 g/L NaCl reduces lifetime ×0.7; acid cleaning every 90 days required.
⚠ RO pre-treatment must include activated carbon to remove free Cl⁻ <0.1 ppm.
Product Features & Application
■ Verified Hydroxyl Radical Yield
Lab data shows •OH concentration of 1.8 mmol/m²·h under 300 A/m² (vs. 1.2 for standard MMO), enabling faster breakdown of azo and anthraquinone dyes.
■ Voltage Stability Under Load
Voltage deviation remains within ±5% over 1000+ h runtime; suitable for automated oxidation loops with pulsed control.
■ Application Scenarios of the Electrochemical Degradation Titanium Anode
✓ Decolorization of reactive and disperse dye effluents
✓ COD polishing before RO/ZLD membrane lines
✓ Electrochemical AOP modules for compact treatment skids
✓ Pre-treatment integration for Fenton or UV oxidation (pH adjusted)

FAQ
Q1: How long will the anode last at 300 A/m² for 6h per day?
A: Estimated at 2.5 years based on 8000 A·h capacity per dm². Use formula: lifetime = 8000 ÷ (A/m² × h/day).
Q2: Can I run this in brine wastewater above 30 g/L NaCl?
A: Yes, but current must be ≤500 A/m². Also expect 30% reduction in service life.
Q3: Can it be used before RO membranes?
A: Yes, but residual chlorine must be removed to <0.1 ppm using activated carbon.
Q4: Does the coating resist Fenton byproducts or UV-AOP conditions?
A: Yes, but Fenton must be neutralized to pH >5.0 before the effluent enters the anode cell.
Q5: What's the scope of your free CAD revision?
A: Up to 3 rounds of changes with 5 dimensions/round. Complex flange redesign quoted separately.
