RAS (Recirculating aquaculture systems)

We can clearly see that the measures we have taken have significantly improved the water quality versus earlier. We see better growth rates, we see lower mortalities, we see better feed conversion rates. All this means that the fish is doing better, and we have reached a higher level of welfare. Hence, we can safely say that these measures on biosecurity have definitely been successful, and the ozone and UV disinfection elements have been a key part of that.”

“The UV disinfection systems procured from ULTRAAQUA is one of the primary biosecurity measures at the hatchery. Water testing has proven it be a highly effective line of defence, helping ensure our young fish experience the best growing conditions.”

“ULTRAAQUA has been a great resource assisting us in achieving our strict biosecurity, efficiency and sustainability goals with products that operate effectively and robustly in our extremely harsh and corrosive environment. Having successfully implemented their systems in our existing operations, it was an easy decision to rely on their support and expertise again with the new expansion.”

“Our high demands for clean and safe intake water were perfectly accommodated by the UV systems from ULTRAAQUA, helping us avoiding bacteria outbreaks and ultimately being able to ensure a higher production yield.”

“The ULTRAAQUA UV system delivers performance beyond our expectations. The system is sized with a large safety margin, which provides optimal UV doses throughout the lifetime of the lamps. The system is easy to install and operate, and we will definitively be working with ULTRAAQUA on our future UV needs.”

“Our ULTRAAQUA UV units are integral parts of our RAS systems, they are trouble-free and we have been impressed by their performance and durability in both freshwater and seawater. The UV sensor output is a great addition and helps with our routine water quality monitoring.”

“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.”

“We find the ULTRAAQUA UV’s to be durable and problem free units for our commercial scale systems. One feature that stands out is the thermal cutoff to protect the units against thermal damage if waterflows stops. They also stand up well to saltwater usage in and around the units”
