UV (ultraviolet radiation) is regarded worldwide as an incredibly reliable, cost-effective and environmentally friendly solution for disinfecting water.

UV radiation destroys the genetic structure of microorganisms in water and prohibits the organisms’ ability to reproduce. Bacteria, viruses and cysts in the water are effectively inactivated (disinfection efficiency 99.99%).

Our facilities cover all needs and capacities. They are approved by FHI (public health institute) and hold Ø-norm certification.


BW is a continuous sand filter developed in collaboration with customers and is used, among other things, to filter and produce drinking water. Contact filtration on this type of filter is characterized by precipitating chemicals (aluminum chloride) added to the water so that flecks are formed in the sand filter which retain both organic and inorganic particles.


Pressure strainers are often used ahead of other processes, in connection with UV systems or as a stand-alone unit to improve water quality, or to prevent damage or deterioration of other equipment.


We supply customized dosing systems for various applications. Together with our subcontractors, we design complete solutions that ensure the quality that our customers expect. A dosing system consists of a dosing pump with accessories, measuring column, documentation and user manual.


Access to clean water is limited in today’s fish farming industry. Norway has access to great water resources, but only a small proportion of it can actually be used for fish production. 

The recycling of water provides solid  control of the water environment and sensible utilization of water sources. Increasingly stricter requirements for wastewater treatment also means that it will become more important to use water more efficiently in the future.
