TOC Reduction UV Unit
A monitored 185 nm ultraviolet oxidation unit that converts trace organic contaminants into more readily removable ionic and gaseous species.
- 185 nm organic oxidation
- Dual hygienic UV reactors
- Monitored high-purity operation
Product Introduction
The TOC reduction UV unit exposes high-purity water to short-wave ultraviolet energy that forms reactive hydroxyl species. These oxidize trace organic molecules into smaller compounds, carbon dioxide and ionic fragments that downstream polishing equipment can remove more effectively. Twin reactors provide practical lamp power and service flexibility in a compact skid.
Key Features
Twin 316L reactor arrangement
High-purity quartz sleeves
UV intensity and lamp-hour monitoring
Sanitary stainless manifolds
Separate protected controller
Configurable series or parallel flow
Integration with ion exchange or degassing
Customer Product Concerns
TOC oxidation performance depends on UV transmittance, lamp output, residence time and the ability of downstream treatment to remove oxidation products.
Trace organics pass conventional deionizationApply 185 nm UV upstream of polishing resin to convert weakly ionized organics into removable products.
Lamp output drifts unnoticedTrack UV intensity and operating hours independently for each reactor.
Oxidation products accumulate in the loopCoordinate the UV duty with downstream ion exchange and membrane-degassing capacity.
Quartz fouling reduces photon transferMaintain feed-water quality and schedule sleeve inspection and cleaning.
Typical Applications
Pharmaceutical purified-water polishingUltrapure laboratory waterSemiconductor rinse-water productionBiotechnology process-water loopsFeed polishing before high-purity points of use
