Ion Exchange Water Purification Systems - Industrial-Grade Demineralized Water Solutions
1. What is Ion Exchange Water Purification?
The Gold Standard for Ultra-Pure Water
• Removes 99.9% of dissolved ions (Na⁺, Cl⁻, Ca²⁺, etc.)
• Produces water with 1-18 MΩ·cm resistivity
• Cost-effective alternative to RO/EDI systems
Market Data: Global ion exchange resin market to reach $2.5B by 2027 (GMI Research).
2. How It Works
Ion Exchange Process Explained
① Cation Exchange
• Removes positively charged ions (Ca²⁺, Mg²⁺, Na⁺)
• Chemical reaction: R-H + Na⁺ → R-Na + H⁺
② Anion Exchange
• Removes negatively charged ions (Cl⁻, SO₄²⁻)
• Chemical reaction: R-OH + Cl⁻ → R-Cl + OH⁻
③ Mixed Bed Polishing
• Combines H⁺ + OH⁻ into H₂O
• Achieves <1 μS/cm conductivity
