ABOUT THE CLIENT

TROUT RAS IN CANADA

Located in Québec, Canada, the Bobines fish farm operates a land-based rainbow trout breeding and processing site. The fish farm has an exceptional focus on sustainability, having implemented best practices for RAS facilities to optimize the production yield while protecting the environment.

The RAS utilizes over 90% water recirculation, which means that less than 10% of the used water comes directly from the groundwater. The farm uses high-quality spring water from the groundwater, which is protected from any external contamination. The cool and constant temperature throughout the year facilitates excellent conditions for the breeding of fish which contributes to their well-being by replicating the natural environment of the fish.

As part of an ambitious expansion plan, the farm has built a new comprehensive RAS facility in 2021.

WHAT THE CLIENT NEEDED

SUSTAINABLE DISINFECTION

The client needed a solution to accommodate the defined requirements of their new hatchery design as part of the comprehensive expansion.

The hatchery design includes 46 fish tanks, 98%+ recirculation rate, 450 m3/h flow recirculation and a capacity of 1 million fry per year.

To accommodate these requirements, it was evident that utilizing UV systems would be a great match, due to the numerous advantages when utilized for complex RAS systems. This includes complete water biosecurity control, water quality management, as well as being completely chemical-free. UV systems are a vital integration of a well-functioning and cost-efficient RAS facility, as they are able of ensuring comprehensive water biosecurity by reducing virus or bacteria outbreaks.

THE SOLUTION

THE BEST DISINFECTION EQUIPMENT ON THE MARKET

For the client, it was important to choose a UV supplier with experience in the aquaculture industry, and especially within UV systems for RAS. The ambitious upgrade required the best possible disinfection equipment on the market, to ensure fulfillment of the defined hatchery design scope for water disinfection and fish welfare.

The installed system was an Open Channel MR28-220PP including ULTRAWIPER™ sleeve wiping technology, capable of meeting the requirements of at least 100 mJ/cm2 for a flow rate of 450 m3/h.

Since installing the Open Channel UV system, the facility has seen a major improvement in the mortality rate, which is now close to 0%.

By choosing Polypropylene (PP) material as the chamber material, excellent corrosion resistance is ensured. The combination of PP chamber material and the ULTRAWIPER™ sleeve wiping technology ensures minimal maintenance requirements, further enhancing operational efficiency.

The installed system will directly contribute to making the facility ensure the lowest possible environmental footprint while offering exceptional breeding conditions for the selected species. The facility is set to install more UV systems in the future upon further operation upscaling.
