Pure & Ultrapure Water Systems

Industrial pure water produced through advanced water treatment technology

Overview

Pure and ultrapure water refers to primary-treated feed water that has been purified through advanced treatment methods such as ion exchange resin, RO (Reverse Osmosis) membrane, and sterilization to remove inorganic salts, organics, microorganisms, and dissolved gases. It is also known as deionized water, DIW (De-ionized Water), UPW (Ultrapure Water), or Blank Water.

Pure and ultrapure water are classified by the degree of ion removal, measured by Specific Resistivity (MΩ) — the higher the value, the purer the water. They are used in pharmaceutical manufacturing, semiconductor and LCD industries, laboratory cleaning solutions, and solvent production.

Industrial Water Utilization Process

Step-by-step treatment process for pure water production

Industrial Water
Micro-filtration
UF
1st Pass RO
Pure-grade (3-15 μS/cm) Water
2nd Pass RO
EDI
Standard Ultrapure (< 17 MΩ·cm) Water
Ion Resin
Ultrapure (≥ 17 MΩ·cm) Water
Without EDI process,
direct resin use results in
high resin consumption

Treatment Process

3-Stage treatment process for pure water production

Pre-treatment

Primary Purification

  • • RO System
  • • Ion Exchange Resin (MBP)
  • • UV Sterilization, etc.
  • • Turbidity / TDS / TOC removal
  • • Heavy metals / partial ion removal
  • • Partial organic removal / sterilization

Secondary Purification

  • • Secondary RO System
  • • EDI System
  • • MDG
