Common feed-water issues
Define the load before the equipment.
- Trace ionic contamination
- Particles and colloids
- Organic carbon and microbial control
- Silica, carbon dioxide and EDI feed limitations
Treatment objective
Ultrapure Water
High-purity water trains configured from the required ionic, organic, particle and microbiological control targets.
Discuss Your Water RequirementsUltrapure / high-purity water
Start with the contamination risk at the use point.
Ionic, organic, particle and microbial targets determine the desalination, polishing and distribution strategy.
Treatment objective
Set a use-specific design basis.
- An application-defined conductivity or resistivity target
- Controlled particles, organics and microorganisms where required
- Stable RO permeate quality suitable for downstream polishing
- Monitoring points aligned with the process risk

- Destination, utilities, installation constraints and documentation needs
FAQ
Questions about ultrapure water.
Is RO alone an ultrapure-water system?
Usually not for demanding applications. RO can provide the main desalination step, while EDI or another polishing stage may be needed to reach and maintain the application target.
Does an RO + EDI system guarantee a specific resistivity?
No. Performance depends on feed quality, carbon dioxide, silica, temperature, pretreatment, recovery, instrumentation and the approved design basis.
What should an ultrapure-water RFQ include?
Include source-water analysis, required quality at each use point, flow profile, operating hours, distribution-loop needs, monitoring requirements, utilities and validation expectations.
