DIGITAL CONTROL for continuous performance

Veolia’s intelligent control architecture ensures every drop of ultrapure water meets spec, continuously, predictably and efficiently.

SMART SYSTEMS. MEASURABLE PURITY. MAXIMUM UPTIME.

In semiconductor manufacturing, water quality has zero margin for deviation. Veolia’s digital control systems provide real-time visibility into every parameter, from resistivity and TOC to flow, temperature and pressure.
Built on decades of fab experience, our automation and monitoring solutions deliver precise control, instant anomaly detection and predictive insights that keep ultrapure water (UPW) systems stable and compliant 24/7.

INTELLIGENT AUTOMATION ARCHITECTURE

Engineered for Stability and Control

Veolia designs and delivers fully integrated control systems for UPW plants, combining PLC-based automation with real-time process analytics. Each control sequence, interlock and alarm is customised to semiconductor requirements, ensuring reliability and fast response under any operating condition.


 KEY FEATURES INCLUDE: 
- Industry-standard  Programmable Logic Controller/Distributed Control System (PLC/DCS) architecture (Siemens, Rockwell, Schneider)
- Full redundancy in critical loops and control processors
- Modular control logic tailored to multi-loop UPW systems
- Standardised control panel fabrication under Underwriters Laboratories/Canadian Standards Association (UL/CSA) certification
- Seamless integration with fab Supervisory Control and Data Acquisition (SCADA) and Building Management Systems (BMS)
