EDI Ultrapure Water System TU Series

Application EDI Ultrapure water (TU Series)

EDI Ultrapure water (TU Series)

How is an EDI ultrapure water system different from conventional ion exchange resins?

1. No chemical regeneration, so no wastewater treatment facilities are needed.

Continuous regeneration of ion exchange resin by direct current

No regeneration waste liquid; no wastewater treatment equipment or neutralization tank required

Ultrapure water grade conditions with feed water FCE < 10 μS/cm; applied to facilities with strict wastewater regulations such as semiconductor manufacturing

2. No strong acids or alkalis are used, lowering corrosion and safety risks.

Electrochemical regeneration with no regenerant chemicals

Precision ultrapure water lines with resistivity of 17.5–18.0 MΩ·cm or higher; reduced risk of corrosion of piping and surrounding equipment and of safety incidents

3. A simpler system configuration reduces the installation footprint.

Regeneration and production proceed simultaneously; uninterrupted operation while maintaining recovery of 95% or higher

No regeneration-related auxiliary equipment such as chemical storage tanks or dosing pumps
