어떤 산업 분야든 이제 환경, 규제, 사회, 경제, 운영 등 다양한 측면에서 해결해야 할 과제가 늘어났다는 점에 있어서 예외가 될 수 없습니다. 단순한 서비스 솔루션 차원을 넘어 실질적인 혁신 역량을 보유한 창의적인 파트너를 찾는 움직임이 생겨나게 된 것 또한 마찬가지 선상에서 생각할 수 있습니다. 베올리아가 존재감이 두드러지는 이유가 바로 여기에 있습니다.

Recycled water for farm-bred salmon

Norwegian company Marine Harvest is the world's leading salmon breeder. It has contracted Veolia to design and build three wastewater recycling facilities that are among the largest and most modern of their kind.



As an operator of highly sensitive facilities, Marine Harvest is constantly seeking technical solutions to optimize its operations and costs. In 2012, the world's leading salmon breeder once again put its faith in Veolia, which had already delivered two wastewater recycling facilities for the company's hatchery in Dalsfjord, in 2010 and 2011. This latest contract covers three new recycling plants, designed specifically for production of young salmon (smolts), to be installed at the Steinsvik site. The hatchery will produce around 5.3 million smolts a year, using only 250 to 500 liters of water per kilogram of fish bred.


Total water treatment capacity at the three plants will reach around 17,000 cubic meters per hour. Installations will be designed to treat both freshwater and seawater, recycling and reusing up to 99% of the water needed for fish breeding. The facilities will use a number of proprietary technologies including AnoxKaldnes MBBR and Hydrotech microscreens, providing a seamless fit with the Kaldnes® RAS solution developed for the aquaculture market by Veolia subsidiary Krüger Kaldnes. Veolia also developed site instrumentation along with the SCADA infrastructure monitoring and control system.
