Ultrapure Water EDI System – 0.25 T/H (250 L/H)
System Overview
This 0.25 ton per hour (250 liters per hour) Ultrapure Water EDI (Electrodeionization) System is designed to produce high-purity water from reverse osmosis (RO) permeate. It integrates advanced EDI technology with precision pre-treatment to deliver consistent, continuous, and chemical-free ultrapure water (up to 18.2 MΩ·cm resistivity), meeting stringent standards for Injection (WFI) or Purified Water.
