HIGHLY SENSITIVE FACILITIES
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.
REDUCING THE ENVIRONMENTAL IMPACT OF AQUACULTURE
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.
