Aluminum Anodizing Water Treatment Systems - Complete Guide
Why Water Quality Matters in Aluminum Anodizing
✔ Prevents contamination of surface treatments
✔ Removes residual chemicals between processes
✔ Maintains consistent quality - Critical for aerospace/automotive applications
✔ Extends bath life - Reduces chemical consumption by 15-20%
Industry Standard: Conductivity 5-10 μS/cm for rinsing water
2 Proven Water Treatment Solutions
1. Ion Exchange Systems
• Best for: Small-medium operations
• Output quality: 1-5 μS/cm
• Maintenance: Regular resin replacement
2. Reverse Osmosis Systems
• Best for: High-volume production
• Output quality: 5-10 μS/cm
• Advantage: Lower operating costs
RO System Process Flow
1. Raw Water Tank
• Equalizes water supply
2. Multimedia Filter
• Removes particles >20 microns
3. Activated Carbon Filter
• Eliminates chlorine/organics
4. Water Softener
• Optional (based on hardness)
5. RO Membrane
• Produces 5-10 μS/cm water
6. Pure Water Storage
• 304/316 stainless steel tanks
Valve Recommendation: Runxin manual valves for reliable control
