100 m³/h RO + EDI Pure-Water System for a Hospital

Home > Projects > 100 m³/h RO + EDI Pure-Water System for a Hospital

RO followed by EDI polishing for a hospital's pure-water demand — no chemical regeneration.

Project Background

A hospital needed pure water for laboratories and central sterile supply with resistivity beyond what RO alone delivers.

Our Solution

RO pretreatment feeding EDI modules for continuous polishing without acid/caustic regeneration.

Process Train

  1. 1Pretreatment
  2. 2RO
  3. 3EDI electrodeionisation
  4. 4Pure-water tank
  5. 5Distribution
