1000LPH Ultrapure Water System Vietnam Electronics
Project Details
With the rapid growth of electronics manufacturing in Southeast Asia, Vietnam has become an increasingly important hub for high-tech industries. Electronics and semiconductor component production require extremely high-purity process water, commonly known as Ultra-Pure Water (UPW). Even trace levels of ions, particles, or organic contaminants can impact product quality during precision cleaning processes.
Global UF recently engineered and delivered a 1000 LPH (1 m³/h) Ultra-Pure Water System for an electronics manufacturing facility in Vietnam. The system was designed to produce semiconductor-grade water with resistivity up to 18.2 MΩ·cm, ensuring stable performance for delicate component washing and cleanroom processes.
The project highlights Global UF’s capability to integrate world-class water treatment components with precision engineering design to deliver reliable UPW solutions.
Project Location: Vietnam
System Capacity: 1000 LPH (1 m³/h)
Application: Electronics component cleaning / precision washing
Design Standard: ASTM D1193 Type I equivalent
Key Component Partners
- DuPont – FilmTec™ RO Membranes
- Siemens – PLC Control System & EDI Module
- Pentair – FRP Pressure Vessels
- Purolite – High Purity Ion Exchange Resin
- CNP – Stainless Steel Pumps
Raw Water Conditions
The system was designed based on the local municipal water supply available at the factory site.
These parameters require multiple purification stages to remove dissolved salts, hardness, organic matter, microorganisms, and particles before reaching ultra-pure water quality.
System Process Design
The UPW system uses a multi-stage purification process to progressively remove contaminants and achieve ultra-low conductivity water.
Process Flow
Raw Water→ Quartz Sand Filter→ Activated Carbon Filter→ Water Softener→ Security Filter→ Double Pass Reverse Osmosis→ Siemens EDI→ Mixed Bed Polishing→ UV Sterilization→ Ozone Sterilization→ Ultra-Pure Water Tank
This design ensures removal of:
- Suspended solids
- Hardness ions
- Dissolved salts
- Organic compounds
- Microorganisms
- Trace ionic contaminants
Process Flow Diagram (PFD)
The system is designed as a fully integrated skid-mounted unit, allowing quick installation and simplified commissioning at the customer site.
Key System Components
1. Reliable Pre-Treatment System
The pretreatment stage stabilizes feed water quality before entering the membrane system.
Main units include:
- Quartz Sand Filter
- Activated Carbon Filter
- Water Softener
All pressure vessels use Pentair FRP tanks, which provide:
- Excellent corrosion resistance
- Long service life
- High pressure tolerance
- Reliable performance in humid environments
Pretreatment significantly reduces turbidity, chlorine, and hardness, protecting downstream membranes.
2. Double Pass Reverse Osmosis
The core desalination process uses Double Pass Reverse Osmosis (RO).
The system is equipped with DuPont FilmTec™ RO membranes, widely recognized for:
- High salt rejection
- Stable performance
- Long membrane lifespan
Double pass RO significantly reduces dissolved ions and conductivity, preparing the water for ultra-high purity polishing.
3. Continuous Deionization with Siemens EDI
After RO desalination, the water enters a Siemens Electrodeionization (EDI) module.
EDI Capacity: 1000 LPH
EDI technology allows continuous removal of residual ions without chemical regeneration. This provides several advantages:
- Continuous production of high purity water
- No acid or alkali chemicals required
- Reduced operational costs
- Stable long-term performance
4. Final Polishing & Microbial Control
To achieve the theoretical limit of ultra-pure water, the system includes a final polishing stage.
Mixed Bed Polishing
The system uses Purolite high-purity ion exchange resin to remove remaining trace ions and reach 18.2 MΩ·cm resistivity.
UV Sterilization
A high-efficiency UV system removes microorganisms and reduces organic contaminants.
Ozone Sterilization
Ozone injection provides additional microbial control and helps maintain ultra-pure water quality during storage.
Smart Control System
The entire system is operated by a Siemens PLC with touch screen HMI.
Operators can monitor in real time:
- Water resistivity
- System flow rates
- Tank levels
- Pump status
- System alarms
This intelligent control platform ensures fully automated and reliable operation.
