What is an EDI system used for?

An EDI system is used to produce high-purity water by removing dissolved ionized impurities from reverse osmosis permeate.

Does EDI require chemical regeneration?

No. EDI uses electrical regeneration and does not require acid or caustic for normal resin regeneration.

Is EDI better than mixed bed deionization?

EDI offers continuous operation and avoids chemical regeneration, while mixed bed systems may still be preferred in some special polishing or backup applications.

What feed water is required for EDI?

EDI typically requires reverse osmosis permeate or other properly pretreated low-conductivity water as feed.

What industries use EDI systems?

EDI is widely used in pharmaceuticals, power generation, electronics, laboratories, fine chemicals, and other industries requiring high-purity water.

Can EDI be integrated with RO?

Yes. EDI is commonly integrated with reverse osmosis systems to create a complete high-purity water treatment line.

Can the system be fully automatic?

Yes. We can provide manual, semi-automatic, or fully automatic PLC-controlled EDI systems.

Can you provide a complete RO + EDI water treatment system?

Yes. We can provide a complete system including pretreatment, RO, EDI, storage, UV, and final polishing options.
