FISH FARMING TECHNOLOGY by Ultraqua, Denmark
The Danish trout and pike perch producer, AquaPri, decided in 2016 to expand its production facilities due to the increasing demand for fish. From a production capacity of 250 metric tonnes of pikeperch farming, adding another 500 metric tonnes plant, AquaPri can now ensure continuous output throughout the entire year.
Protecting against bacteria with enhanced UV systems The new plant was originally designed without a UV system in place, but throughout the startup phase, problems with bacteria grew rapidly. Therefore, ULTRAAQUA’s challenge was to properly design and size a UV system for retrofit, that effectively ensured protection against bacteria, as well as increasing the survival rate and drastically reducing the use of medication. AquaPri’s pikeperch farm is a state-of-the-art RAS plant, where the stable production and biosecurity is kept through several of ULTRAAQUA’s UV Channel systems. The main systems are two MR100-350SS Channel units which were chosen for keeping the recirculated water free of diseases. The units have a disinfection volume of 2600 m3/h/ unit in a very compact area, where the footprint of the 35kW unit is under 1m2. Each unit holds 100pcs of 350W lamps, with a guaranteed lamp lifetime of 16,000 hours, which can save up to 22 percent in operational costs. Ultraaqua has developed the most powerful yet most efficient UV-systems in the market, where the long lifetime and efficiency is a result of 20 years research and development work.
