ULTRAAQUA UV is a manufacturer of advanced UV water disinfection systems for a range of water treatment applications. Founded in 1996 by two Danish scientists to solve the increasing water safety challenges by utilising innovative technologies, today it has grown into an international company with more than 10 000 UV disinfection systems worldwide.

ULTRAAQUA UV continuously partakes in multiple research projects in collaboration with municipalities, universities, and companies. Their key focus is on developing new and advanced water treatment solutions based on UV technology. ULTRAAQUA UV has its full-scale laboratory, indoor and outdoor testing areas, and research department with top-level academics with vast experience in diverse water industries.

Relying on continuous research activities enables the company to provide users with advanced water security within municipal and industrial applications such as drinking watermunicipal wastewateraquacultureswimming poolsfood and beveragestormwater overflow (CSO),  landfill leachate, semiconductor and microelectronics, horticulturepharmaceuticals and zoos and aquariums. Besides standard UV disinfection, the company also delivers Advanced Oxidation Process (AOP) for treatment of groundwater pesticides, and Total Organic Carbon (TOC) reduction solutions for complex applications.

ULTRAAQUA UV operates worldwide through a carefully selected distributor network and is active in more than 120 countries.

Our distributors



ULTRAAQUA UV installs its AOP systems for discharge re-use for beer production in Carlsberg facility in Fredericia. With ULTRAAQUA UV help Carlsberg now recycles 90% of all process water and halve water usage at its brewery while reducing energy consumption by 10%.


Based on medium pressure UV technology and accumulated industry knowledge over the years the company engineered ULTRATRON™ series – the ultimate high flow disinfection solution that can be integrated into the smallest of places. ULTRATRON™ versatility and series of benefits enable it to be integrated across almost all water treatment applications and industries.


In order to further advance potable water disinfection, ULTRAAQUA UV scientists developed patent-pending Swirlflow™ technology providing additional security and energy savings for its users. The enhanced series has also obtained ÖNORM M 5873-1 validation based on SWIRLFLOW™ technique (Pat.pend.)

The same year UV-system no. 10 000 was shipped. The company over the years managed to create a strong network of reliable distributors and clients around the globe with over 80% of its sales taking place outside Denmark, making the company further establish its stronghold as an international business.


To further advance the increasingly more challenging biosecurity levels in the aquaculture industry, the ULTRABARRIER™ series was engineered. The UV systems were designed particularly for water intake point for intensive aquaculture farming facilities. To further solidify the latest technology’s reliability – after detailed testing, the latest UV systems were officially validated by EU Environmental Technology.


The first series designed specifically for potable water was validated by international ÖNORM M 5873-1 and DVGW standards. Even though almost all UTRAAQUA UV systems can be implemented for drinking water, the ÖNORM validation delivers an additional layer of security of the UV technology as it passes through comprehensive third-party testing to obtain it.


In the process of delivering the MP system to one of the swimming pools in Sweden, ULTRAAQUA UV experts took notice of how impractical swimming pool water treatment was. Inspired by this, they developed an advanced method to treat swimming pool water by utilizing drum filters. Upon installation of the new solution, the Swedish municipality’s and companies’ interest grew quite rapidly, and to deliver a well-rounded swimming pool solutions, InBlue was founded together with Jysk Svommebadsteknik A/S. The company successfully operates to this day continuing to offer highly innovative, intelligent pool water treatment solutions.


The shipping industry and ballast water were under continuous scrutiny due to the damage upon its release back into the marine environment. As environmental regulations were becoming increasingly more strict, to address this the shipping giant Maersk, pump industry leader Desmi and ULTRAAQUA UV scientists collaborated and developed Desmi Ocean Guard skid solution for ballast water treatment. The units have gone through few alterations since, but are still widely used as part of Ballast Water Management Systems (BWMS) at Desmi. The UV systems for DESMI Ocean Guard has also been approved by IMO standard.


During their research project in the swimming pool industry, Jens and Ole proved the unparalleled effectiveness of Medium-Pressure UV for the destruction of the chloramines. Inspired by the industry’s clear need for the solution, ULTRAAQUA UV launched its first MultiRay medium pressure UV systems. The good relationship in the industry ensued and ULTRAAQUA UV started getting stronghold of the swimming pool sector in the Scandinavian market.


With the company’s growing success – an challenging project reached the hands of the owners. The layout specifications required additional and complex construction work in order to accommodate UV channels available in the industry. To avoid it, the engineers came up with one more unique solution – the first ever wall mounted UV channels. The newly developed solution once again was a success and later applied to multiple other projects. Just like with inclined channels, wall mounted channel solution remains exclusively on ULTRAAQUA UV portfolio. During this time ULTRAAQUA UV products started gaining prominence in the municipal water sector as well.


The expansion of advanced intensive aquaculture farms and RAS outside the Nordic region quickly demonstrated the need for UV solution for warm saline water environments. To address this, the ULTRAAQUA UV team selected ingenious and unconventional material – UV-C stabilized polypropylene for UV reactors. The material proved to be the best compromise between chemical and heat resistance and long term physical stability. To this day ULTRAAQUA UV is the only UV manufacturer offering polypropylene UV systems which absolutely excels in the farming of warm saline water species.


During their work, Ole and Jens discovered how much challenge channels for lower water levels presented in the municipal industry. In their attempt to solve it, the scientists designed inclined UV channel – a first-ever channel UV system allowing a range of different water levels.


The aquaculture sector demand for diverse UV solutions encouraged the company to further advance its technology and widen its product portfolio. This resulted in the development and launch of channel UV systems. Based on the positive feedback, a growing reputation, and an increase of interest from international markets showed that the company was on the right track.


Soon after the owners made the decision to focus only on UV technology the very first low-pressure MR1-75W UV system was launched. The first clients of the UV units were primarily trout farmers in Denmark and Finland and due to product success – soon after multiple lamp systems were launched together with 220W systems. During the same year, the brand name ULTRAAQUA UV was born as well.


The company SKJØLSTRUP & GRØNBORG A/S was founded by two life-long friends and environmental scientists – Ole and Jens. Most of their primary work consisted of consultancy services about water treatment, primarily for RAS. During their studies at Aalborg University, they began the development of UV technology. In addition to ultraviolet sterilization, research work also focused on ozonation, biofiltration, and filtration of particles. Until 2006 Jens and Ole remained in close collaboration with Aalborg University throughout their R&D activities.
