Advantages of EDI (electric desalting)

1. No acid-base regeneration is required. The operation of electric desalting is safe and the treatment of wastewater becomes simple.
2. It can be produced continuously. The production of electric desalting is continuous, which avoids the complex regeneration operation in the process of using mixed bed, and reduces many spare equipment.
3. There is no need to treat waste acid and alkali. There is no neutralization and discharge treatment system for waste acid and alkali. The concentrated water of electric desalting can be directly discharged or returned to the inlet of RO (the concentrated water in EDI is much less than pure water).
4. The installation conditions are simple. During installation, the electric desalting occupies a small area, which can be met by most standard plants. For lower plants, it can be solved by horizontal configuration of electric desalting module.
5. The system design is simple. The module design of electric desalting is easy to achieve the flow rate of 450 t / h or even higher.
6. The operation cost is low. Compared with various mixed beds, the electric desalting system is competitive in price.
7. Practical design. For the electric desalting system, it is easy to maintain or increase or decrease the capacity of the equipment. When the membrane stack has to be replaced, it can be completed with very little downtime on site.
8. Easy to install and maintain. The electric desalting device allows the flow of other membrane stacks to be redistributed to meet the maintenance requirements of a certain membrane stack without changing the performance of the system.
9. The water quality is stable. The quality of effluent from electric desalting is stable and reliable. There will be no water quality change like that of ordinary mixed bed.

10. Standard design. The use of standard units, like building blocks, can meet the needs of users with different water production.
