ABOUT THE CLIENT
SWIMMING CENTER IN DENMARK
ICV, Idrætscenter Vendsyssel, is a new state-of-the-art swimming center being constructed in Vrå, Northern Jutland, Denmark. The 2.400 m² facility represents a significant investment of DKK 120 million and is scheduled for completion in spring 2026. The swimming hall features a 25-meter pool with eight lanes, a leisure pool with a waterslide, and a dedicated wellness section, all forming part of a modern and inspiring activity house that creates an attractive meeting point for the local community.
The facility is designed to host both large and small events, including concerts, lectures, sports events, and training camps. By being physically connected to the existing Idrætscenter Vendsyssel, the new swimming center reinforces the cohesion of the entire sports complex, serving as a comprehensive “catch-all” solution for wellness, recreation, and community engagement.
WHAT THE CLIENT NEEDED
ENERGY-EFFICIENT WATER TREATMENT FOR AN EXCEPTIONAL BATHER EXPERIENCE
The client required a future-proof water treatment solution capable of delivering an outstanding visitor experience while meeting high standards for operational efficiency, sustainability, and water quality.
A central requirement was to implement energy-efficient, top-of-the-line technology to reduce energy consumption, optimize daily operations, and support long-term environmental goals. At the same time, maintaining consistently clean, safe, and crystal-clear water across multiple pool environments was essential to ensuring a comfortable and enjoyable experience for all user groups.
The facility also needed a holistic approach that would minimize chlorine by-products to improve both water and air quality, reduce water consumption, and ensure that bathers could spend extended time in the pool environment without the irritation or discomfort traditionally associated with chlorine-heavy facilities.
THE SOLUTION
THE INBLUE CONCEPT FOR THE HEALTHIEST BATHING WATER
To meet the requirements for superior water quality, operational efficiency, and an exceptional bather experience, the comprehensive inBlue concept was implemented by the water treatment company, Fjordblink, throughout the facility. As part of the ULTRAAQUA group, inBlue delivers a revolutionary, holistic solution that combines optimized hydraulics, advanced filtration, and integrated UV disinfection to achieve exceptional bathing water quality with minimized operating costs.
At the core of the solution are the inBlue drum filters, serving as the primary means of particle filtration. Operating purely by gravitation, the drum filters capture skin cells and other particles before they have time to dissolve and form chlorinated by-products, while yielding significant energy savings compared to conventional filtration. Particles are backwashed and discharged to the sewer in a concentrated stream, often within hours of being introduced to the water.
Not least, to complement the filtration step, MULTIRAY medium-pressure UV systems were installed to ensure effective disinfection and continuous chloramine reduction, providing protection against chlorine-resistant pathogens such as Cryptosporidium and Giardia.
The UV systems were carefully dimensioned to match the operational needs of each pool area. Due to the immediate filtration of organic matter, the UV systems are only disinfecting part flow, as the generation of combined chlorine is reduced significantly, as well as the energy consumption.
UV system specifications:
- Splash Pool (VB01) – 85 m³/h – MultiRay MP1-2000SS
- 25m Pool (VB02) – 120 m³/h – MultiRay MP1-2000SS
- Warm Water Pool (VB03) – 80 m³/h – MultiRay MP1-2000SS
- Spa (VB05) – 63 m³/h – MultiRay MP1-1000SS
By integrating the full inBlue concept with ULTRAAQUA’s MultiRay UV technology, Vrå Svømmehal now benefits from a state-of-the-art water treatment process that ensures cleaner water and air, happier guests, reduced operating costs, and a strong contribution to long-term environmental responsibility.
