UK firm’s UV system approved for Norway aquaculture use

Aquaculture technology supplier Steinsvik has welcomed the Norwegian Veterinary Institute’s decision to approve the use of Wigan-based atg UV Technology’s Wafer UV system for use in the aquaculture industry. Norway-headquartered Steinsvik, which has a Scottish base in Fort William, sells the UV products.

“We are very pleased to finally get the approval,” said Geir Arne Albertsen, head of water engineering in Steinsvik. “We have been working towards this for a long time. atg UV Technology might be a new name for some in the industry, but they have had approved UV systems for drinking water in Norway since 2001.

Compact solution

“Steinsvik started the collaboration with atg in 2013. The approved products comprise a new UV series especially developed for the aquaculture industry. The design and development phase have resulted in a compact solution with low pressure loss as well as maintaining the high quality that atg UV Technology is known for.”

“The process of obtaining the approval have been a demanding one, however the aquaculture industry is food production so a strict set of rules is needed for new products,” continued Albertsen.

“The field testing was done with the Norwegian institute for water research, (NIVA) as the independent third party, and started in 2016. The sampling and practical test was concluded in October of 2017. These UV products are a perfect fit with our other products such as AquaFilter and complete water treatment plants.

Demanding environment

"The test took place on board at Norsk Fisketransport wellboat MS Namsos. Wellboats are a demanding environment. Planning and logistics in such a project is not simple when the vessel is in full operation. The boat is in continuous motion, and the crew are working. Atg UV Technology has led the project and thanks to the solid efforts of all involved parties, the project went as planned."

According to Steinsvik, the Wafer range provides the latest in medium pressure UV lamp technology. A series of multi-lamp configurations using a range of medium pressure UV lamps, the specially designed in-line UV reactors provide optimum flow distribution and hydraulic performance. The Wafer range offers a wide variety of water treatment applications, treating capacities of 1.0 m3/hr to more than 5,000 m3/hr in a single, high output, low footprint UV system.
