Electronic Industry Laboratory Reverse Osmosis System with EDI Technology 0.25T to 1T Capacity 15-18.25 MΩ·cm Pure Water
EDI (Electrodeionization) technology combines with reverse osmosis and other purification devices to effectively remove ions from water. The EDI module contains ion exchange resin divided into working resin and polishing resin sections, with a working front boundary between them. The working resin removes most ions while the polishing resin targets difficult-to-remove weak electrolytes.
EDI systems produce ultrapure water with resistivity reaching 15-18.25 MΩ·cm and can operate either continuously or intermittently based on application requirements.
EDI equipment is installed after reverse osmosis systems, replacing traditional mixed bed ion exchange technology (MB-DI) to deliver stable ultrapure water production.
- Consistently stable water quality output
- Full automation capability for operational efficiency
- Continuous operation without regeneration shutdowns
- Chemical-free regeneration process
- Reduced operating costs
- Compact footprint for space optimization
