The desire for higher production yields has driven the marine species farmers to shift to increasingly more controlled environments – recirculated aquaculture systems (RAS). A truly successful RAS that makes reared species thrive requires an advanced disease control solution due to continuous water re-use, accumulation of species droppings, and nutrients used in its feed.
This further intensifies as microbiology is disrupted by increasing stocking densities and feeding, potentially making RAS an ideal breeding ground for various bacteria and viruses. UV systems are the best available technology for tackling this issue – including increasing numbers of bacteria outside of the biofilter. ULTRAAQUA UV delivers tested and proved UV solutions for controlling the risk of bacteria outbreak in the RAS without altering other crucial water qualities such as pH and temperature.
Based on in-field experience and R&D ULTRAAQUA UV systems have been designed to meet disinfection requirements even for the most intensive RAS and as of today are responsible for disinfecting over 100 000m3/h RAS water worldwide.
In order to accommodate a high variety of climates and flows, ULTRAAQUA UV systems for aquaculture offer gravity flow, open channel systems, and closed vessel systems – in both stainless-steel and polypropylene materials. This enables the company to provide the best solution for either influent, effluent, or process water that can be installed or retrofitted in a variety of RAS layouts.

“The result of the UV’s that we bought from ULTRAAQUA is good. I’m satisfied with the result, it can reduce total bacteria in the water and improve hatching rate to a higher percentage than before.”

“One of the reasons we chose ULTRAAQUA UV is because we had a pleasant conversation at AquaNor in Trondheim. They are easy to reach in case of questions and the prices were competitive. The required level of biosecurity determines the need for a certain lamp output and ULTRAAQUA UV has done a great job in assisting with this by showing literature that explains the needed dosage to kill a certain disease vector.”
