De Nora highlights APAC projects and PFAS technologies at SIWW

Italian multinational company specialising in sustainable electrochemical, water treatment technologies and in the emerging green hydrogen industry — De Nora showcases its work across multiple collaborative projects, to improve the effectiveness of per- and polyfluoroalkyl substances (PFAS) removal technologies at Singapore International Water Week (SIWW) 2024.

With its expertise in electrochemistry and water treatment, De Nora addresses water challenges by removing Contaminants of Emerging Concern (CECs), including PFAS and micropollutants through oxidation and disinfection technologies, combined with filtration and adsorption solutions.

De Nora’s SORB contaminant removal systems are designed to remove contaminants from water including arsenic and now PFAS, which is increasingly regulated globally due to the impact on public health.

The difficulty of optimising PFAS removal processes to ensure effective treatment, while maximising media life is reflective of its 30-year expertise against the challenges with Arsenic removal. The company has extensive references, having commercialised what is now one of the two primary methods of its removal from water.

Since the 1970s, De Nora has advanced water treatment with ozone. The introduction of De Nora Capital Controls Ozone/ Advanced Oxidation Processes (AOP) and UV/ AOP systems sets standards regarding removal of a host of contaminants including micropollutants and 1,4-dioxane from water sources.

“At De Nora, our mission is to combat continually evolving treatment challenges and eliminate harmful contaminants from water,” said Marwan Nesicolaci, De Nora CEO. “We look forward to sharing how our solutions and support have been purposely designed toward the needs of Asia-Pacific customers at SIWW.”

In Asia, De Nora recently opened a new electrode production line at a Suzhou plant in China, which tripled the site’s total production capacity. The recent regional localisation of its Capital Controls Ozone generators in the region added ClorTec on-site sodium hypochlorite generators, De Nora TETRA filters and SEACLOR seawater electrochlorination systems.

Customers in the region now benefit from full lifecycle management, covering project design, manufacture, project execution and aftersales support.

De Nora has also recently won projects for CECHLO systems in the APAC region, including Goryeong Water Treatment Works in Korea, and is currently finishing commissioning an installation in Mount Isa, Australia. The latter, located in a remote part of Australia, serves as a hub-and-spoke arrangement to produce and distribute fresh hypochlorite to local communities, instead of shipping hypochlorite in bulk from long distances.

In Hong Kong, a hybrid configuration combining on-site electrochlorination and chlorine gas feed technologies eliminate disinfection safety risks from liquid chlorine and provides stable, sustainable, and greener chlorine management is now fully operational in all ten water treatment works, marking the largest installation of the CECHLO-MS systems in Asia.
