Electrodeionization (EDI)
Electrodeionization (EDI) is used after reverse osmosis to obtain desalinated water with low conductivity and silica values.
​
EDI uses ion exchange membranes, ion exchange resins, and electricity to produce high-quality water without downtime for regeneration. EDI is an alternative to conventional mixed bed exchangers.

Advantages of EDI
Continuous process
EDI is a simple, continuous process.
Compact systems
EDI systems are very space-saving thanks to their compact design.
No use of chemicals
EDI uses chemical-free regeneration. This eliminates operational interruptions caused by regeneration processes as well as the storage and handling of acids and alkalis.
