Ultrapure Water Systems

Ultrapure water is water from which practically all dissolved ions, organic compounds, particles and microorganisms have been removed. Its quality is measured mainly by conductivity/resistivity (down to 18.2 MΩ·cm), TOC and microbiological limits. It is required wherever even trace impurities would affect a product, an analysis or equipment.

Applications

Pharmaceutical production (purified water), laboratories, hospitals and dialysis, electronics and semiconductor manufacturing, cosmetics, high-pressure steam boilers and turbines, and battery production.

Typical Treatment Train

• Pretreatment: multimedia and activated carbon filtration, softening or antiscalant dosing
• Reverse osmosis: single or double pass RO to remove the bulk of dissolved salts
• Electrodeionization (EDI): continuous polishing without chemical regeneration
• Mixed-bed ion exchange: final polishing to the highest resistivity
• UV and final filtration: TOC reduction, microbial control and particle removal
• Storage and loop: hygienic tanks and recirculating distribution loops

Monitoring

Online conductivity/resistivity, pH and flow measurement keep the quality under continuous control, and alarms warn before the water goes out of specification.
