Ion Exchange Water Treatment: 2025 Complete Guide
How Ion Exchange Works
- Dual Resin Process:Cation Resin: Replaces Ca²⁺/Mg²⁺ with H⁺Anion Resin: Replaces Cl⁻/SO₄²⁻ with OH⁻
- Result: H⁺ + OH⁻ → H₂O (Pure Water)
- Efficiency: 99%+ dissolved solids removal
Industry Data: 60% of industrial demineralization uses ion exchange (IWA 2023)
3 Key Ion Exchange Processes
1. Water Softening
- Resin Type: Na⁺ form cation resin
- Removes: Ca²⁺, Mg²⁺ (Hardness)
- Capacity: 30,000-50,000 grains/ft³
2. Dealkalization
- Resin Combination: Weak acid cation + Strong base anion
- Targets: HCO₃⁻, CO₃²⁻
- Benefit: Prevents scaling
3. Full Demineralization
✔ Mixed Bed configuration
✔ Produces 18 MΩ·cm water
✔ Used in: Pharmaceuticals, power plants
Technical Specifications
| Parameter | Softening | Dealkalization | Demineralization |
|---|---|---|---|
| Output Quality | <1ppm hardness | <10ppm alkalinity | <1μS/cm |
| Regeneration | NaCl brine | HCl/NaOH | HCl/NaOH |
| Flow Rate | 10-15 gpm/ft³ | 8-12 gpm/ft³ | 5-8 gpm/ft³ |
| Resin Life | 5-8 years | 3-5 years | 2-4 years |
Regeneration Process (5 Steps)
1. Backwash
- Removes particulates
- 50% bed expansion for 10-15 mins
2. Chemical Injection
- Cation Resins: 4-10% HCl
- Anion Resins: 4% NaOH
- Softening: 10% NaCl brine
3. Slow Rinse
- Critical for complete regeneration
- 30-60 minute duration
4. Fast Rinse
- Removes residual chemicals
- 5-15 minutes
5. Return to Service
✔ Quality verification
✔ System reset
