Ultrapure Water Equipment: High-Purity Water for Critical Applications

1. Working Principle

Ultrapure water equipment operates through a combination of advanced purification technologies. Raw water first goes through pre-treatment to remove large particles and suspended solids. It then passes through reverse osmosis (RO) to eliminate most inorganic salts and organic substances. Next, ion exchange resins remove residual ions. Finally, ultrafiltration and UV sterilization are used to eliminate microorganisms, endotoxins, and remaining organics, delivering water that meets ultrapure standards.

2. Key Components

  • Precision Filter: Traps fine particles.

  • RO Membrane: The core component that removes most impurities.

  • Ion Exchange Resin: Performs deep-level ion removal.

  • UV Sterilizer: Destroys the DNA of bacteria and viruses.

  • Ultrafiltration Membrane: Removes micro-particles and macromolecules.

3. Process Flow

Raw Water → Raw Water Booster Pump → Multi-Media Filter → Activated Carbon Filter → Water Softener → Precision Filter → First Stage RO → pH Adjustment → Intermediate Water Tank → Second Stage RO → Pure Water Tank → Pure Water Pump → UV Sterilizer → Microporous Filter → Point of Use

4. Equipment Features

  • High Water Quality: Resistivity up to 18.2 MΩ·cm.

  • Fully Automated Control: Smart PLC system enables automatic operation, real-time monitoring, and fault alerts.
