Capable of continuous production of high-purity purified water
It is capable of continuous production of purified water with a specific resistivity of 10 MΩ·cm or higher.
No need for regeneration chemicals
Because it is electrically regenerated, no regeneration chemicals are required.
It is capable of reducing running costs compared to conventional ion exchange methods.
Easy operation management and maintenance
Operation control is easy as there is no regeneration operation with chemicals.
Space-saving
Because of its unit design, it can be installed in a space-saving manner.
Workflow of EDI Equipment
Introduction of feed water. Pretreated water enters the system and passes through an initial treatment stage where larger contaminants and particles are extracted.
Ion exchange procedure. As the feed water flows through the resin beds, positive ions are substituted for hydrogen ions (H+) and negative ions for hydroxide ions (OH-). This initiates the deionization of the water, though it does not achieve total purification independently.
Electrochemical reaction. Upon the application of power to the electrodes, H+ and OH- ions are compelled towards their respective electrodes due to the electric field created. This movement boosts ion removal efficacy, continually regenerating the ion exchange sites within the resin beds.
Removal of concentration stream. The concentrated stream consisting of extracted impurities is drained through a separate outlet while the purified deionized water is output as the end product.
Continuous operation. Unlike conventional deionization techniques that necessitate intermittent regeneration with chemicals, EDI systems maintain a constant operation without the need for chemical regeneration, making them more proficient and environmentally considerate.

Maintenance of EDI Equipment
1. Maintain accurate operational records, carefully observing and recording the technical parameters of each node.
2. Although most equipment uses fully automatic intelligent control, regular inspections are still necessary.
3. Pay close attention to pretreatment equipment, regularly checking if the automatic cleaning system is functioning correctly and ensuring the effluent water quality meets standards (focusing on contamination index and ORP index).
4. Replace precision filter cartridges regularly; replace them promptly when the inner layer of the filter cartridge turns gray.
5. Continuously monitor the pressure, flow rate, and water quality indicators of the reverse osmosis unit during operation. Analyze and resolve any abnormalities promptly, and perform chemical cleaning when necessary.
6. For the EDI precision electro-deionization unit, pay attention to the technical parameters such as permeable water quality, inlet and outlet pressures for desalinated and concentrated water, operating voltage, and current. Regenerate and perform chemical cleaning promptly based on changes in these parameters.
7. For polishing resin filters, pay attention to the inlet water quality during daily management. Water that does not meet design requirements should not be introduced, otherwise it will fail too quickly.
8. Adhere to the principle that "if the effluent water quality of each treatment unit is not up to standard, it cannot enter the next treatment unit." Otherwise, it will increase the processing load of the next unit and cause irreversible damage.
Methods For Adjusting PH In EDI Equipment
To make sure EDI works well and lasts a long time, it's important to keep the pH levels in the feedwater just right. Here are some ways to adjust the pH:
Check that the pH of the feedwater is between 5.5 and 7.5, which is the right range.
Use automatic pH control devices to keep everything in check all the time.
When you need to change the pH, use acids or bases that are safe for food.
