26/09/2017: Protecting against bacteria with enhanced UV systems

by Ultraaqua, 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.

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. The guaranteed 16,000 hours lifetime is achieved by an advanced optimisation between the lamps and its ballast.

The Channel system is developed for fully automatic use. An advanced PLC control is constantly monitoring and adjusting the electrical parameters of each individual lamp to ensure their optimal performance to meet dose requirements in the most energy efficient way.

Henning Priess, owner and managing director of AquaPri, is very satisfied with his newly installed ULTRAAQUA channel units, since the facility experienced a log four reduction in bacteria count after installing the units.
