    1、 Equipment name: EDI device

    2、 Specification and model: hdnedi-12000

    3、 Equipment brand: Wenzhou Haineng wzhdn

    4、 Product Description:

    1、EDI is a combination of electrodialysis and ion exchange each other together in addition to the new technology of salt, this process takes electrodialysis and ion exchange, both short offset each other, it is using ion exchange can deep desalting to overcome polarization and electrodialysis desalination is not complete, and use of electrodialysis polarization and water and electricity produced from H + and OH - ions to realize automatic resin regeneration to overcome the defect of resin by chemical regeneration after failure, and therefore EDI technology is a kind of perfect desalination technology.

    2. In the EDI desalting process, the ions in the water and the hydroxide ions or hydrogen ions in the ion exchange resin are exchanged, and then these ions are transferred into the concentrated water;

    3. The above exchange reaction takes place in the fresh water chamber of the module. In the fresh water chamber, the hydrogen ion in the anion exchange resin exchanges with the anion in the water, and the hydrogen ion in the cation exchange resin exchanges with the cation in the water;

    4. Under the action of direct current, the exchanged ions migrate along the surface of resin ball and enter the concentrated water chamber through ion exchange;

    5. The anions with negative charge are attracted by the anode, and these ions enter into the adjacent concentrated water chamber through the negative membrane, while the adjacent positive membrane does not allow them to pass through,

    These ions are blocked in the concentrated water, and the cations with positive charge are attracted by the anion separator. These ions enter into the adjacent concentrated water chamber through the cation membrane, but the adjacent anion membrane does not allow them to pass through. These ions are blocked in the concentrated water;

    6、In concentrated water, ions from both directions maintain neutral electricity. At the same time, the current is proportional to the migration of ions. The current consists of two parts, one of which is caused by the migration of removed ions, the other by the migration of H+ and OH- ions ionized by the water itself.

    7. When the water flows through the fresh water chamber and the concentrated water chamber, the ions gradually enter into the adjacent concentrated water chamber from the fresh water chamber, and are carried out of the EDI module by the concentrated water;

    8、Under the action of high voltage ladder, water will generate a large number of H+ and OH- by electrolysis, and these H+ and OH- generated in place will carry out continuous regeneration of ion exchange resin. Therefore, ion exchange resin in EDI components does not need chemical regeneration.

    9. This is the EDI desalting process.  

    5. Technical features:

    1. It can be produced continuously with high water production resistivity ≥ 15m Ω. Cm-18m Ω. Cm

    2. Water production rate can be as high as 90%

    3. The quality of produced water is stable. No need for acid alkali regeneration

    4. No sewage

    5. The system has high automation, simple operation and low labor intensity

    6、 Technical requirements:

    1. Water supply: RO produced water, conductivity ≤ 20 μ s / cm (recommended<10μs/cm )
