Product Introduction – Ultrapure Water Products

Ion exchange resin tower system (IEX)

Summary

The traditional water treatment technology uses tower containers filled with ion exchange resins (cation exchange resins, anion exchange resins, or mixed bed resins) to deeply remove dissolved salts and ions in water through displacement reactions between exchangeable ions on the resin and impurity ions in the water. Regular use of acid and alkali chemical agents is required for regeneration to restore exchange capacity.

 

Specialty

Deep desalination and ion removal: It can efficiently remove the majority of anions and cations (including difficult to remove ions such as silicon and boron) in water, and the purity of the produced water is extremely high (with a resistivity of up to 18 M Ω· cm).
Strong adaptability to water quality: The tolerance for fluctuations in incoming water quality (such as TOC, hardness, salt content) is relatively high, and it can handle RO produced water with high TOC content.
Mature and reliable: Mature technology, rich application experience, stable and reliable operation.
Flexible configuration: Different combinations such as single bed (cation bed/anion bed), multiple bed (cation bed+anion bed), or mixed bed (cation anion resin mixture) can be used according to water quality requirements.

 

Purpose

Mainly used for preparing ultrapure water or as a precision processing unit, as well as in situations where water quality requirements are extremely high:
Ultra pure water refining: After RO or EDI, it is used as the final polishing unit to ensure the highest purity of the produced water (such as in semiconductors and pharmaceuticals).
Deep desalination: as a post-treatment or alternative solution for RO (when the influent is not suitable for RO or when the desalination rate is extremely high).
Special ion removal: selective removal of specific ions (such as nitrate removal, boron removal, heavy metal recovery).
Boiler feedwater treatment: Ensure the quality of boiler feedwater and prevent scaling and corrosion.
Laboratory pure water preparation.
