Product Description
EDI Module | Electrodeionization
EDI is a new type of ultra-pure water technology developed in the 1990s, Its development is a revolutionary advance in the history of pure water production technology. EDI can replace traditional ion exchange technology, produce stable deionized water. Unlike the hybrid ion exchange device, the EDI system does not require chemical regeneration, and does not have to be stopped for Adding resins or chemical regeneration. Therefore, EDI can achieve continuous production of water, and water quality is stable.Meanwhile, equipment investment and operating expenses are minimized.
EDI Membrane Stack: Continuous Chemical-Free Deionization Technology
The EDI Membrane Stack represents an advanced electrochemical water purification technology that seamlessly integrates electrodialysis (ED) and mixed-bed ion exchange (IX) principles. By applying a direct current (DC) field across alternating cation-selective and anion-selective membranes, it achieves continuous removal of ions from feedwater without chemical regeneration.
Core Working Principle:
Purification occurs within resin-filled chambers. Feedwater – typically pretreated reverse osmosis (RO) permeate – enters dilute chambers packed with mixed-bed ion exchange resins. Under the DC field, cations migrate through cation-exchange membranes toward the cathode, while anions move through anion-exchange membranes toward the anode. Contaminants concentrate in adjacent channels and are flushed to waste. Critically, water molecules dissociate at the resin interface, generating H⁺ and OH⁻ ions that continuously regenerate the resin in-situ, eliminating the need for acid/alkali chemicals.
Key Performance Advantages:
EDI systems deliver ultra-pure water output with resistivity reaching 18.2 MΩ·cm, surpassing ISO Class 3 standards. This technology achieves >90% water recovery through concentrate stream recycling, significantly reducing wastewater volume. Unlike conventional IX, EDI operates 24/7 without regeneration downtime, enabling fully automated production. Its modular architecture allows scalable deployment across flow rates from 300 L/h to 7,500 L/h.
Critical Feedwater Requirements:
Optimal performance requires RO-treated feedwater with conductivity below 20 µS/cm, total hardness under 0.5 ppm (as CaCO₃), total organic carbon (TOC) below 0.5 ppm, and free chlorine under 0.02 ppm. Operating temperature must be maintained between 5–35°C (25±5°C ideal) to ensure stable ion mobility and minimize membrane stress.
Industrial Applications:
EDI is indispensable in industries demanding relentless purity. In semiconductor fabrication, it removes trace ions to sub-ppb levels for wafer rinsing and photolithography processes. Pharmaceutical manufacturers rely on it to produce Water for Injection (WFI) compliant with USP/EP pharmacopeia standards. Power plants deploy EDI for high-pressure boiler feedwater to prevent scaling and corrosion. Emerging applications include feedwater purification for PEM hydrogen electrolyzers (requiring ultra-low silica/TOC) and ultrapure water supply for advanced laboratory instruments like HPLC and ICP-MS.
Technical Innovations:
Modern stacks feature titanium-ruthenium electrodes with oxidation resistance exceeding 5-year lifespans, and reinforced membranes rated for pressures up to 6 bar. Patented full-resin-filling technology across all chambers enhances electrical conductivity, slashing energy consumption by >60% versus conventional designs. Multi-channel flow distribution ensures stable resistivity (±0.1 MΩ·cm) despite feedwater fluctuations.
