Electrodeionization (EDI) Systems

🔄 Principle of Operation

The process combines ion exchange, membrane separation, and an electric field.

Under direct current, ions migrate through ion-exchange membranes and are removed from the water stream, while the resin is continuously regenerated without chemicals.

🏗 Design

Systems include:

• EDI modules (resin-filled compartments)
• anion and cation exchange membranes
• electrodes (anode/cathode)
• DC power supply
• piping and control system

Modules can be scaled according to required capacity.

🌍Applications

• power generation (boiler feed water)
• pharmaceutical industry
• electronics and microelectronics
• laboratories and ultrapure water production

🧱 Advantages

• no chemical regeneration
• continuous operation
• stable water quality
• low operating costs
• environmentally friendly process

📊 Technical Specifications

Main parameters:

• water quality — up to 18 MΩ·cm (ultrapure)
• capacity — configuration-dependent
• demineralization level — ultrapure water
• chemical-free operation
• integration with RO systems
