Ultrapure water production is not a single filtration step but a multi-stage deep purification system. Growel's UPW systems integrate several advanced technologies to ensure output water meets stringent industry standards, including ASTM, SEMI, USP, and ISO specifications.

• Pretreatment stage: Removes large suspended particles and some organic impurities from feedwater, reducing the load on downstream membrane processes.
• Reverse osmosis (RO): Uses semipermeable membranes to retain dissolved solids, bacteria, and most organic matter.
• Advanced deionization (EDI/ion exchange): Removes residual trace ions through electrodeionization or ion-exchange resin, raising water quality to the megohm level.
• Ultraviolet (UV) sterilization and filtration: Further kills microorganisms and degrades trace organic compounds, maintaining a sterile system environment.
• Microfiltration and terminal monitoring: High-precision microporous filtration captures extremely fine particles, while real-time online water-quality monitoring supports process continuity and reliability.

Together, these stages allow the system to address contaminants at different scales, from suspended solids to dissolved ions and microbial matter.

Growel offers several UPW system types to accommodate different production scales and site constraints, from laboratory research and development to large-scale wafer fabrication.

The choice of configuration depends on water demand, required quality standards, available floor space, and plans for future capacity expansion.

Modern ultrapure water systems focus not only on water quality but also on intelligent operation and environmental performance. Growel's systems include remote monitoring and automated control functions that support predictive maintenance and reduce unplanned downtime.

By optimizing water circulation paths, the systems can also lower water consumption and waste discharge, helping industrial users pursue sustainability targets without compromising process reliability.
