Understanding the Ultra Pure Water Process

Ultra Pure Water (UPW) plays a vital role in industries where even the smallest impurity can lead to severe consequences, directly affecting entire production systems. UPW is widely used in electronics and semiconductor manufacturing, pharmaceuticals, food processing, and more. Achieving and maintaining such purity requires a complex production process supported by advanced equipment.

In this article, let’s explore the UPW production process and the role of liquid particle counters in quality control with Filterfine Vietnam.

What is Ultra Pure Water (UPW)?

Ultra Pure Water (UPW) is water purified to a level where virtually all impurities are removed, including dissolved ions, organics, particles, bacteria, and dissolved gases.

Water purity is typically measured by conductivity or resistivity—the higher the resistivity, the purer the water. UPW is thousands of times purer than drinking water, containing less than 1 part per billion (ppb) of impurities.

UPW is indispensable in industries that demand the highest quality:

• Semiconductor manufacturing: even a microscopic particle can cause system failure.

• Pharmaceuticals: ensuring safety and drug efficacy.

• Advanced laboratories: eliminating external variables for accurate results.

UPW Production Process

To meet the stringent purity requirements, the UPW production process goes through six consecutive stages:

1. Pre-treatment
   Removes large impurities, suspended solids, and organics using multimedia filters, activated carbon, and ultrafiltration.

2. Reverse Osmosis (RO)
   Uses semi-permeable membranes to remove most dissolved ions and molecules, allowing only water molecules to pass through.

3. Ion Exchange
   Exchanges remaining ions with hydrogen and hydroxide ions to produce deionized water.

4. Electrodeionization (EDI)
   Continuously removes dissolved ions using ion-exchange resins and an electric current, achieving the high resistivity required for UPW.

5. Final Filtration
   Employs submicron filters to eliminate bacteria and fine particles, bringing water close to absolute purity.

6. Polishing & Storage
   UV light breaks down organic molecules, while specialized storage tanks and recirculation loops maintain purity.

Why is Ultra Pure Water so important?

• Semiconductors: a single particle can reduce chip yield, causing millions in losses.

• Pharmaceuticals: prevents impurities from compromising drug safety and efficacy.

• Biotechnology: ensures a reliable research environment.

Therefore, UPW production is not only complex but also requires continuous and precise monitoring.

The Role of Sampling Systems and Liquid Particle Counters

Maintaining UPW purity is a continuous challenge. Two critical tools for UPW quality control are sampling systems and liquid particle counters.

Sampling Systems

• Collect water samples at each purification stage.

• Detect early deviations from standards.

• Enable timely adjustments before failures occur.

Liquid Particle Counters

• Apply optical laser technology to detect ultrafine particles in water.

• Provide continuous data on particle size and counts.

• Enable real-time monitoring at Points of Use (POU) in UPW systems.

These counters serve as “gatekeepers”, ensuring UPW consistently meets stringent standards throughout the production line.
