NURES® purifies your radioactive liquids

NURES® technology purifies your radioactive liquids efficiently with lower costs. It is based on patented, 100% inorganic, highly selective ion exchange (“IX”) materials. The Treat-series IX materials have been developed from a nuclear power plant operator’s perspective since the 1980s. NURES® technology is proven in the most challenging conditions at our customers’ installations, including the liquid treatment at the Fukushima Daiichi site where extremely stringent purification criteria have been applied. We thrive to deliver the best possible radionuclide purification technology to our customers with continuous R&D activities and product development.
