  • As the oil and gas sector reels from a shortage of bulk bleach, De Nora Neptune has been named partner of choice for a new Martin Water Midstream development in the Permian Basin – the epicenter for onshore oil and gas production in the US.

  • De Nora has been recognized in the 2022 Water Europe Innovation Awards, named best in the Water Technology & Infrastructure category for its sludge ozonation application in advanced sewage treatment.

  • In line with Saudi Vision 2030, De Nora Water Technologies and Saline Water Conversion Corporation (SWCC) expand their partnership with the signing of a memorandum of understanding (MOU) on brine mining and water electrolysis research. The MOU also includes innovations to the vacuum-based Capital Controls Chlorine Dioxide Generators used in desalination pre-treatment and disinfection, which were approved by the Desalination Technology Research Institute (DTRI) earlier this year.  

  • Learn about what’s available and what’s coming in the safe and permanent destruction of PFAS.

  • Providing simplified solutions for complex problems, De Nora unveils standard designed systems to target per- and poly-fluoroalkyl substances (PFAS) in water treatment. The preconfigured SORB systems employ proven methods of contaminant removal to reduce PFAS in water sources to a non-detectable level, including ion exchange (IX) and granular activated carbon (GAC).

  • Helping ensure partners are prepared to adequately protect communities from future water-dwelling threats, De Nora will host a free webinar at 11 a.m. ET on Wednesday, March 30, to discuss a contaminant of concern: 1,4-dioxane. The webinar will include an overview of principal De Nora Capital Controls® UV and Ozone advanced oxidation process (AOP) technologies spearheading treatment efforts to remove this synthetic chemical, increasingly found in potable water sources and deemed a likely human carcinogen by the US Environmental Protection Agency (EPA). The webinar will focus on how to select the best process to remove this volatile organic compound (VOC) amidst a complex matrix of water characteristics.

  • Continuing to shape the future of water treatment in the Middle East, De Nora announces its latest approval from the Desalination Technology Research Institute (DTRI), a division of Saudi Arabia’s Saline Water Conversion Corporation (SWCC), for its vacuum-based Capital Controls Chlorine Dioxide Generators.

  • A prominent figure for thought leadership in the water industry, De Nora will host a one-hour virtual roundtable event in celebration of World Water Day, an annual observance that aims to highlight the importance of fresh water. The roundtable, held Tuesday, March 22 at 11 a.m. ET, will feature a diverse group of panelists who will lead an engaging and informative discussion on the topic of groundwater, the theme of this year’s World Water Day. 

  • Committed to addressing water scarcity with innovation in treatment technologies, De Nora will sponsor the highly anticipated International Specialty Conference on Innovation in Desalination. The conference will be held on May 30 through June 1 in Jeddah, Saudi Arabia, a region addressing the global challenges of enhancing desalination water quality. This premier event focuses on the latest achievements of desalination science and technology and provides a forum for incubation and exchange of ideas between industry stakeholders. 

  • De Nora announces the launch of the ClorTec® SD disinfectant generator. When used as directed, the ClorTec SD generator produces a ready-to-use (RTU) chlorine-based disinfectant that kills 99.9% of germs (Refer to EPA Registration Number: 91386-1 as amended November 2021 for use directions).  The RTU solution is generated on-site in quantities adequate to address the challenge of continuously cleaning surfaces in hospitals, senior care facilities, offices, factories, schools and many other critical locations.  

  • Since 2010, DE NORA TETRA Denite filter technology has effectively lowered nitrate, phosphorus and total suspended solids (TSS) from wastewater discharged into the Four Mile Run region of the Potomac River, improving water quality conditions of the Chesapeake Bay and surrounding environment.

  • A decade after installation, De Nora – a global leader in the delivery of sustainable technologies – reports uninterrupted operation and successful biological nutrient removal at the Arlington County Water Pollution Control Bureau (WPCB). Since 2010, DE NORA TETRA® Denite® filter technology has effectively lowered nitrate, phosphorus and total suspended solids (TSS) from wastewater discharged into the Four Mile Run region of the Potomac River, improving water quality conditions of the Chesapeake Bay and surrounding environment.

  • Continuing its critical mission of delivering first-class water and wastewater treatment solutions, De Nora is pleased to announce the finalization of two major acquisitions, adding Grundfos’ ISIA S.p.A. and the UV Technologies Division (“CCUV”) from Calgon Carbon Corporation to its portfolio of water treatment solutions. The addition of these chlorine dioxide and ultraviolet water treatment technologies will allow De Nora to further enrich its comprehensive range of solutions to its customers and reinforce its leadership in combating emerging contaminants and complex water treatment challenges.

  • De Nora, a global leader in the delivery of sustainable technologies, has today 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.
