Design For specific Requirement -Electro deionization
- Product description: Design For specific Requirement -Electro deionization
Product introduction
EDI (Electro deionization, continuous electrolysis desalting technology) is a kind of pure water manufacturing technique which combined with ion-exchange technology, ion exchange membrane technology and Ion migration technology.
The desalination rate of EDI equipment can be as high as 99%. If using a set of reverse osmosis equipment for preliminary desalting before the EDI, and the the EDI desalting can produce ultrapure water with a resistivity up to 15MΩ.cm .
Applications
Ultrapure water for pharmaceutical factory, electronics , semiconductor, precision machinery industry, biotechnology, chemical reagents, seawater or brackish water desalination, as well as other industries.
