2000L/H DI Water Purification Equipment - Mixed Bed Technology

Intro: Need ultra-pure water for critical industrial processes? Our 2T/H (2000L/H) ion exchange water purification system delivers exceptional water quality through advanced resin technology. Achieve up to 18 MΩ·cm resistivity for your most demanding applications.

How Ion Exchange Water Purification Works

Ion exchange technology uses specially formulated resins to remove dissolved ions from water through reversible chemical reactions.

The Science Behind It:

 • Cation Exchange: Removes positive ions (Ca²⁺, Mg²⁺, Na⁺)

 • Anion Exchange: Removes negative ions (Cl⁻, SO₄²⁻, HCO₃⁻)

 • Mixed Bed: Combines both resins for highest purity

Simple Example:

HR + Na⁺ → NaR + H⁺

This shows sodium ions swapping places with hydrogen ions on the resin.

Key System Configuration Options

Three Main Ion Exchange Types:

1. Cation Exchange Units (Acid-Bed)

 • Removes calcium, magnesium, sodium ions

 • Releases hydrogen ions into water

 • Essential for hardness removal

2. Anion Exchange Units (Alkali-Bed)

 • Removes chloride, sulfate, bicarbonate

 • Releases hydroxide ions into water

 • Completes demineralization process

3. Mixed Bed Polishers

 • Combines cation and anion resins

 • Produces highest purity water

 • Achieves 1-18 MΩ·cm resistivity
