Ramboll, Glitrevannverket, and CrayoNano Launch Pilot Project for UV-LED Water Treatment System in Norway
Norway—In a partnership to advance water treatment technology, Ramboll, Glitrevannverket, and CrayoNano have joined together for a pilot project to install and evaluate a UV-C LED water treatment system in a municipal plant. The project is part of the Norwegian Institute of Public Health’s 2023 program for technology development in the water industry focused on empowering municipalities to test and implement innovative technologies for more cost-effective and sustainable water supply solutions. It is the first of its kind at the municipality level in Norway. It aims to demonstrate that UV-C LED technology can provide a safer and more sustainable method for disinfecting drinking water.
The one-year project will study the operation and effectiveness of UV-C LED technology in disinfecting drinking water, aiming to increase the robustness and process control of the UV-treatment and lower the operation costs. Glitrevannverket, which supplies clean drinking water to over 155,000 people, has partnered with Ramboll and CrayoNano to install and test a UV-C LED water treatment system at the Setervannet water treatment plant in Asker municipality. The UV-C LED drinking water disinfection system is designed and manufactured by one of CrayoNano's customers, featuring CrayoNano's CrayoLED™ UV-C LED with the germicidal wavelength of 275 nm. Setervannet, a reserve water source, allows for a controlled study without impacting the regular water supply. This site was chosen for its comparable water quality to many of Norway's raw water sources. This initiative marks a significant advancement in ensuring the safety and stability of drinking water using UV-C LED technology.
Project Goals and Evaluation:
The main objective of this pilot project is to study and evaluate a safe, stable, and effective disinfection process for drinking water using LED technology. LED technology, which has already transformed the lighting industry, offers a promising alternative to traditional mercury-containing UV lamp systems. The UV-C LED installation is targeted for early Q4-2024. Throughout the project, the team will collect data to evaluate LED technology against current treatment standards in terms of technical performance and economic efficiency. The project will also assess the potential improvements and optimization in disinfection processes, such as faster initiation and UV-C dose adjustment, range of water quality treatment, and the overall robustness of the disinfection process.
Industry Impact and Future Potential:
This pilot project is set to provide valuable insights and feedback to both research and commercial sectors developing LED technologies for UV disinfection. By demonstrating the practical applications and benefits of LUV-C LED systems in a real-world setting, the project aims to encourage further investment and innovation in this field. The findings will help determine if commercially available UV-C LED systems are suitable for full-scale use in Norwegian water treatment facilities.
About Glitrevannverket:
Glitrevannverket IKS is an inter-municipal company owned by the municipalities of Asker, Drammen and Lier. The main purpose of Glitrevannverket is to supply the owner municipalities with good, sufficient and safe water through environmentally focused, competent and systematic management of water sources and water supply systems.
Glitrevannverket owns and operates four treatment plants that supply water to about 155,000 people in the owner municipalities, and to the customers in Frogn and Holmestrand municipality. The water sources are Glitre, Røysjø and Holsfjorden. The Setervann treatment plant is a reserve source and is not in daily use.
Glitrevannverket is one of the largest providers of drinking water in Norway, known for its commitment to sustainability and innovation in water treatment technologies.
