How Electrodeionization Systems Work

An electrodeionization (EDI) system operates by integrating ion exchange, electrodialysis, and DC electricity to achieve water demineralization. Typically used for reverse osmosis polishing, EDI processes water post-reverse osmosis (RO) to remove residual ions and achieve ultra-pure water quality (up to 18.2 MΩ/cm). The system consists of chambers filled with ion exchange resins, separated by cation- and anion-selective membranes. When water enters, a DC electric field drives ions toward electrodes: cations to the cathode and anions to the anode. These ions pass through the resins, which maintain stable conductance, and are captured in concentrate chambers, leaving purified water in the dilute chamber. The chemical-free regeneration process occurs as H+ and OH- ions, generated by water splitting, continuously regenerate the resins, eliminating the need for chemical additives. Continuous electrodeionization (CEDI) ensures uninterrupted operation, with concentrate streams recycled or discharged, maintaining high efficiency.

Main Advantages of Electrodeionization Systems

• Chemical-Free Regeneration: EDI systems eliminate hazardous chemicals, reducing environmental impact and operational costs.
• Continuous Operation: CEDI enables non-stop water demineralization, minimizing downtime compared to traditional ion exchange systems.
• High Purity Output: Produces UPW with low conductivity and silica levels, critical for semiconductors and pharmaceuticals.
• Compact Design: EDI systems require less space, ideal for space-constrained facilities.
• Sustainability: Reduces chemical waste and energy use, aligning with global sustainability goals.
