The water sector is on the cusp of a significant shift, as an international collaboration is set to accelerate the adoption of UV-C LED technology for municipal water disinfection. This isn’t just about replacing old tech with new; it’s about future-proofing our water infrastructure against regulatory changes and environmental concerns. The project, spearheaded by Norwegian utility Glitrevannverket, Danish engineering consultancy Rambøll, and UV-C LED manufacturer AquiSense, is more than just a pilot—it’s a testament to the power of international cooperation and innovation.
At the heart of this project is the PearlAqua Kilo unit, a compact design that integrates LEDs, eschewing chemicals and mercury-based UV lamps. This isn’t just a nod to environmental responsibility; it’s a proactive step towards compliance with the Minamata Convention, which aims to phase out mercury use and mining by 2032. With 98% of the UV disinfection market currently reliant on mercury-based systems, this project could be a game-changer.
The Setervann water treatment facility near Asker, Norway, has been chosen for its water quality, comparable to many Norwegian sources. This isn’t just about testing technology; it’s about understanding its real-world implications. The project will evaluate technical performance, operational stability, and cost efficiency, providing valuable insights for future implementation.
“This installation is an important step in assessing UV-C LED technology’s application in municipal water treatment,” said Tor Håkonsen, Global spearhead manager for water and wastewater treatment. This isn’t just about Norway; it’s about setting a global precedent. The project’s outcomes could guide the water industry worldwide, as utilities seek alternatives to traditional mercury-based lamps.
Glitrevannverket, supplying drinking water to 160,000 people, sees this as more than just a technological upgrade. “Water is our most important nutrient, and we must always look for better ways to ensure safe drinking water,” said managing director Marius Asheim. This isn’t just about technology; it’s about responsibility and leadership.
AquiSense, one of the first to commercialise UV-C LED technology for disinfection, is excited about the project’s potential. “It’s encouraging to see a European utility take the lead on the adoption of UV-C LED disinfection,” said Oliver Lawal, founder & CEO, AquiSense Inc. This isn’t just about a single project; it’s about a shift in the industry’s approach to water treatment.
As the project unfolds, it will be crucial to monitor its progress and engage in open dialogue about its implications. This isn’t just about adopting new technology; it’s about shaping the future of the water sector. The outcomes of this project could challenge norms, spark debate, and accelerate the adoption of UV-C LED technology worldwide. The water sector is watching, and the world is waiting. This is more than just a pilot project; it’s a step towards a more sustainable, responsible, and innovative future.
