Description
Product Overview
In recent decades, mixed bed ion exchange technology has been the standard for the preparation process.
Due to the need of periodic regeneration and regeneration process using plenty of chemicals (acid and alkali) and pure water, and bring environmental problems, therefore need to develop without acid-base ultra-pure water system.
Because the traditional ion exchange has unable to meet the need of modern industry and environmental protection, and so will membrane, resin and electrochemical principle of combining become EDI water treatment technology of a revolution.The regeneration of ion exchange resin, and is used to, so no more need acid,and satisfied with world environmental requirements.
Since EDI membrane technology industrialization in 1986,there have  thousands of EDI systems been installed in the factory of world , especially developed in the pharmaceutical, semiconductors, power and surface cleaning industry etc , and has widely used inenergetically in wastewater treatment, beverage and etc .
EDI device is used in reverse osmosis system, instead of traditional mixed ion exchange technology (MB-DI) production stable DI - deionized water.
To mixed ion exchange technology,EDI technology and has the following advantages:.
1.the quality stable,the resistivity up to 17MΩ.CM(0.058us/cm).
2.To realize automatic control.
3.No regeneration downtime 
4 don't need chemical regeneration.
5.low operating cost.
6 small workshop area
7 no sewage discharge.

Working Theory
Electrodeionization uses electrical current to force a continuous migration of contaminant ions out of the feed water and into the reject stream while continuously regenerating the resin bed with H+ (hydrogen) and OH- (hydroxyl) ions that are derived from water splitting. The patented flow process of the dilute and concentrate streams make the Omexell module completely unique .
Feed water (dilute stream) enters the Omexell module from below and is diverted into vertically spiraled cells known as the 'D' (dilute) chambers. The dilute stream flows vertically through ion-exchange resins located between two membranes (an anion membrane specifically designed to allow migration of only anions, and acation membrane specifically designed to allow migration of only cations).
Concentrate enters the module through the center pipe from below and is diverted into spirally flowing cells known as the 'C' (concentrate) chambers.
DC current is applied across the cells. The DC electrical field splits a small percentage of water molecules (H2O) into Hydrogen (H+) and Hydroxyl (OH-) Ions. The H+ and OH- Ions attach themselves to the cation and anion resin sites, continuously regenerating the resin. Hydrogen ions have a positive charge and Hydroxyl ions have a negative charge and each will migrate through its respective resin, then through its respective permeable membrane and into the concentrate chamber due to their respective attraction to the cathode or anode. Cation membranes are permeable only to cations and will not allow anions or water to pass, and anion membranes are permeable only to anions and will not allow cations or water to pass.
Contaminate ions dissolved in the feed water, attach to their respective ion-exchange resin displacing H+ and OH- ions. Once within the resin bed, the ions join in the migration of other ions and permeate the membrane into the 'C' chambers. The contaminant ions are trapped in the 'C' chamber and are swept away. The feed water continues to pass through the dilute chamber and is purified and is collected on the outlet of the "D" chambers and exits the EDI module. All EDI module product flows are collected and exit the system.
