Product Introduction
The Titanium Anode For Electrolytic Wastewater Treatment is designed to break down high-COD and ammonia-containing industrial effluents through indirect electrochemical oxidation. Its Ir–Ta oxide coating delivers high oxygen evolution potential, promoting hydroxyl and active chlorine radicals generation without chemical additives. Suitable for systems requiring stable performance at 200–300 A/m², this anode structure is compatible with plate, mesh, and flow-through reactors.

Product Features & Application
■ High OEP Ir–Ta Coating → More •OH → Higher COD Reduction
→ At 200 A/m², •OH production measured at 3.6 mmol/m²·h (lab test)
→ COD removal efficiency >92% under simulated printing wastewater (COD 1500 mg/L)
■ Stable Voltage Profile → Reduced Side Reactions → Longer Lifespan
→ Voltage fluctuation <±5% under 300 A/m² after 2000 h runtime
→ Chloride-based oxidation without secondary sludge
■ The Titanium Anode For Electrolytic Wastewater Treatment is applied in:
✓ Treatment of pesticide, dyeing, and pharmaceutical wastewaters
✓ Ammonia nitrogen oxidation post-biological treatment
✓ High-COD greywater ZLD pretreatment
✓ Integrated electrochemical AOP units in compact plants

FAQ
Q1: Can I use this anode in mixed-organic electroplating wastewater?
A: Yes, but pre-precipitation of metals or complexation is advised before electro-oxidation.
Q2: How is the coating performance verified?
A: Each batch includes adhesion and thickness test records (ASTM B571). Optional SGS verification is available.
Q3: Can it run continuously above 600 A/m²?
A: Short-term only. Continuous use over 600 A/m² requires forced cooling and may reduce lifespan by 40–50%.
Q4: What mounting types are available?
A: A: We offer bolt tabs, clamp lugs, or slotted flanges depending on your tank design.
