EDI (Electrodeionization) or CEDI (Continuous Electrodeionization) is an ideal solution for producing ultrapure water thanks to its continuous operation, chemical-free process, low operating costs, and stable water quality. This technology is increasingly favored in industries that require extremely high water purity standards such as electronics, pharmaceuticals, food & beverage, laboratories, and more—where water quality plays a critical role in accuracy and reliability.

EDI (CEDI) systems are extensively used in industries that demand ultrapure water, where the output water quality must maintain extremely low and stable conductivity. Key application sectors include:
-
Electronics & Semiconductors
-
Pharmaceuticals & Healthcare
-
Food & Beverage Industry
-
Chemical Manufacturing
-
Laboratories & Research Facilities
KEY ADVANTAGES OF EDI OVER TRADITIONAL MIXED BED ION EXCHANGE SYSTEMS
1. High Purification Efficiency
EDI systems can achieve purification rates up to 99%, effectively removing nearly all remaining ions from water. This results in very high water purity, suitable for critical applications. The system also supports large flow rates with a compact footprint.
2. No Chemical Regeneration Required
Unlike conventional ion exchange systems that require acids and caustic soda for resin regeneration, EDI uses electricity for continuous in-place resin regeneration. This enhances safety, cleanliness, and environmental friendliness.
3. Continuous Operation
EDI systems operate continuously without downtime for regeneration, ensuring uninterrupted water quality and minimizing system downtime.
4. High and Consistent Water Quality Output
EDI can produce water with resistivity up to 18 MΩ·cm, meeting stringent quality requirements in industries such as pharmaceuticals, electronics, and microchip manufacturing.
5. Optimized Long-Term Operating Costs
Although EDI may require higher initial investment compared to traditional ion exchange systems, it significantly reduces chemical, wastewater treatment, labor, and downtime costs, providing excellent long-term cost efficiency.
6. Highly Automated and Easily Integrated
EDI is easily integrated into modern RO-UPW systems and can be managed via SCADA or PLC-based automation systems for streamlined control and monitoring.
