I.Overview
EDI (Electrodeionization) is a water treatment technology that combines ion exchange resin with electrodialysis membranes to continuously produce high-purity water (with resistivity as high as 18 MΩ·cm or more). It is a core component of ultra-pure water production. “EDI marks the transition of ultra-pure water systems from ‘chemical regeneration’ to ‘continuous physical purification,’” and in the semiconductor/pharmaceutical industries, EDI has replaced mixed-bed systems as an industry standard (SEMI F63).
II.Main process
Raw Water → Raw Water Tank → Booster Pump → Flocculant/Reducer Dosing → Activated Carbon Filter → Ultrafiltration (UF) → Scale Inhibitor Dosing → Security Filter → 1st Stage High-Pressure Pump → 1st Stage RO → pH Adjustment → Intermediate Tank → 2nd Stage High-Pressure Pump → 2nd Stage RO → Purified Water Tank → EDI Booster Pump → UV Sterilizer → Cartridge Filter → EDI System → Ultra-Pure Water Tank → Transfer Pump → TOC Removal Unit → Polishing Resin → Final Filter → Point of Use
III.Core Components and Materials of EDI
| Component | Material and Function | Industry Standard | ||||
| Ion Exchange Resin | Nuclear - grade granular resin (e.g., Purolite® NRW1600), particle size 0.6 - 0.7 mm, exchange capacity ≥ 1.8 eq/L | ASTM D1782 | ||||
| Ion Exchange Membrane | Perfluorosulfonic acid membrane + perfluoroquaternary ammonium membrane (e.g., DuPont Nafion®), ion selectivity > 98% | SEMI F73 | ||||
| Diaphragm Flow Channel | Food - grade PP or PVDF, thickness 0.8 - 1.0 mm, turbulent flow design to prevent scaling | FDA 21 CFR 177 | ||||
| Electrode | Titanium - plated ruthenium anode/stainless steel cathode, corrosion - resistant current density > 100 mA/cm² | ISO 9001 | ||||
IV.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
