About the entity

We are a multinational company and a leading designer of sustainable technologies, energy saving products and water treatment solutions.


De Nora, a global leader in the delivery of sustainable technologies, has announced the acquisition of the UV Technologies Division (“CCUV”) from Calgon Carbon Corporation. The deal includes municipal and industrial water ultraviolet disinfection brands RAYOX, SENTINEL and C3 SERIES UV, as well as the products, brands and assets of Hyde Marine, a world leader in UV ballast water management systems.

The acquisition, which was signed on June 7 and is expected to close on July 1, brings together the strong delivery track record, expertise and capabilities of De Nora and CCUV.  

De Nora Water Technologies CEO Dr. Mirka Wilderer commented, “We are thrilled about this acquisition! It positions us to offer a complete range of solutions across the disinfection spectrum, for both regulated and non-regulated water management. CCUV Technologies enhances the value we deliver to our customers by offering solutions that are ideal for their unique water treatment needs. This supports our mission to be a partner of choice in the water treatment market.”

CCUV introduced one of the first advanced oxidation processes (AOP) UV systems to the market. UV AOP technology is capable of treating several contaminants that are not easily removed by other technologies. The acquisition will allow De Nora to accelerate worldwide efforts to combat these contaminants of emerging concern (CECs) and “forever chemicals” increasingly found in water supplies alongside its Capital Controls® ozone AOP solutions. Mitigation strategies are not one-size-fits all for notorious contaminants like chlorinated alkenes (DCE, TCE, PCE), 1,4-dioxane, vinyl chloride, NDMA and many others. CCUV brings to De Nora their extensive expertise and an innovative treatment algorithm to optimize the design of large-scale UV AOP treatment systems.

In the marine market, the acquisition will help stop the dispersal of invasive living species into new habitats via ballast water carried by commercial shipping vessels. The acquisition brings UV ballast water treatment to the De Nora portfolio. With their existing BALPURE® electrochlorination (EC) ballast water management system, De Nora will become one of the few global enterprises offering both UV and EC technologies in the marine market. This capability comes key at a time when the industry faces unprecedented demand for high quality water treatment technologies required to meet the International Maritime Organization’s Ballast Water Management Convention (BWMC).

Paolo Dellachà, CEO of De Nora, enthusiastically welcomed CCUV as he expressed that, “the synergies between the two businesses are very strong – each brings exceptional experience, strong track records, similar value propositions and well-aligned market channels. Both CCUV and De Nora are known for their emphasis on innovation and market development. I eagerly await the opportunity to meet the talented and expert colleagues who will be joining us from CCUV in the coming weeks.”

Until and after transaction closing, CCUV will continue to maintain normal operations towards customers and suppliers. For questions or concerns, please reach out directly to your normal business contacts.
