EDI Ultrapure Water Treatment Equipment (Electro-Deionization system) is an advanced water purification technology designed to produce high-purity and ultrapure water continuously without chemical regeneration.

It integrates ion exchange membranes, resin technology, and electrical current to remove dissolved ions efficiently, making it a preferred solution for industries requiring strict water quality standards such as semiconductors, pharmaceuticals, power plants, and food processing.

What is EDI Ultrapure Water Treatment Equipment?
EDI (Electro-Deionization) is a modern water treatment process that combines:
Ion exchange membranes
Ion exchange resin
Direct current (DC) electric field
This system continuously removes dissolved ions from water, producing stable ultrapure water without the need for chemical regeneration, unlike conventional ion exchange systems.

Working Principle of EDI System
The EDI system operates through a continuous electrochemical process:
Water flows through alternating cation and anion exchange membranes placed between electrodes under a DC electric field.

Process Breakdown:
Cations (positive ions) move toward the cathode
Anions (negative ions) move toward the anode
Ions pass through selective membranes into the concentrate chamber
Purified water remains in the dilute chamber

Result:
Dilute chamber produces ultrapure water
Concentrate chamber collects and removes ions

This continuous process ensures stable desalination, ion removal, and high-purity water production without interruption.
