A global semiconductor manufacturer established a new advanced manufacturing facility in Singapore to support growing demand across the Asia-Pacific region. The facility required a highly reliable ultra-pure water (UPW) system designed to meet stringent semiconductor process requirements and a tight delivery window.
The challenge
The project presented several key challenges:
- High UPW demand of approximately 700 m³/day, with provision for 30% future capacity expansion
- Stringent water quality specifications, including resistivity, TOC, boron, silica, and trace contaminants
- Tight project timeline for design, delivery, installation, and commissioning
- Water efficiency expectations, aligned with Singapore’s regulatory and sustainability objectives
- Alignment of technical requirements and expectations across multiple project stakeholders
The customer required a partner capable of addressing these challenges through robust process design, integrated solutions, and strong execution support.
“Throughout the project, the Xylem team provided consistent technical guidance and strong cross-functional coordination, ensuring alignment across stakeholders and maintaining momentum against a demanding timeline.”
The solution
Xylem Water Solutions and Services partnered with the customer to deliver a comprehensive, end-to-end ultrapure water (UPW) solution, combining process engineering, advanced treatment technologies, and lifecycle services.
The engagement began with a deep-dive technical audit of the facility’s operating conditions and stringent purity requirements. This resulted in a scalable design featuring Vantage® PTI Multimedia Filtration and Vantage PTI Activated Carbon Filtration for robust pretreatment, followed by Vantage™ Reverse Osmosis (RO). To meet the extreme purity standards required for semiconductor manufacturing, we implemented Ionpure® VNX Ultra CEDI for advanced deionization, and ATG™ UV systems for TOC removal. To maximize sustainability, we integrated a dedicated RO reject recovery system, significantly reducing water waste and lowering long-term operational expenditure (OPEX).
Navigating a strict 14-month timeline during a period of global resource scarcity required a proactive procurement strategy. We leveraged our global network and long-standing vendor relationships to prioritize and secure long-lead items, such as PVDF piping and electrical components, well ahead of schedule. This global reach, combined with a phased delivery model, insulated the project from market volatility and ensured all critical hardware arrived on-site in time for commissioning.
Our commitment extends beyond the build via a comprehensive lifecycle service package, including a dedicated Operation & Maintenance (O&M) contract, ensuring the system maintains peak performance from day one.
