industrial EDI Water Treatment Service, Factories

XJY's EDI water treatmentÂ combines ion exchange with electric drive. Under the traction of electric field force, anions and cations in water migrate to the concentrated water chamber through selective ion exchange membranes respectively, continuously removing almost all ionic impurities in the water, thereby preparing high-purity ultrapure water efficiently and stably without the need for large amounts of acid and alkali regeneration.

Introduction To EDI Water Treatment Equipment

What is a desalination machine?

EDI water treatment equipment combines ion exchange with electric drive. Under the traction of electric field force, anions and cations in water migrate to the concentrated water chamber through selective ion exchange membranes respectively, continuously removing almost all ionic impurities in the water, thereby preparing high-purity ultrapure water efficiently and stably without the need for large amounts of acid and alkali regeneration.

EDI Water Treatment Equipment Process

Core Functions Of EDI Water Treatment Equipment

EDI System Technology

EDI (Electrodeionization), also known as electric desalination, is a new ultrapure water preparation technology. This technology combines electrodialysis technology and ion exchange technology, realizes the directional migration of ions under the action of DC electric field through the selective permeation of membranes and resins. This completes deep desalination while generating hydrogen and hydroxide ions to regenerate the resin continuously without acid-base chemical regeneration.

Frequently Asked Questions (FAQ)

What is EDI technology in water treatment?

EDI (Electrodeionization) is a green water treatment technology that removes ions from water using electricity, ion-exchange membranes, and resin, without requiring chemical regeneration.

How does EDI differ from traditional ion exchange?

Unlike traditional ion exchange that requires acid and alkali for resin regeneration, EDI uses an electric field to regenerate the resin continuously, making it more eco-friendly and cost-effective.

What level of water purity can EDI achieve?

EDI systems can consistently produce ultrapure water with a resistivity of 15 to 18.2 MΩ·cm, suitable for high-precision industrial applications.

Is the EDI system easy to maintain?

Yes, the modular design allows for easy installation and maintenance. Since there is no need for chemical handling, the operational safety and simplicity are significantly improved.

Which industries benefit most from EDI water equipment?

EDI is widely used in the pharmaceutical, electronics, power generation, and chemical industries where stable, high-purity water is essential for production.
