Adaptable solutions for sustainable fish-farming
Process water
Water quality is the most critical aspect of an aquaculture system. Water purification helps ensure satisfactory fish health and affects the quality of the harvested product. Successful aquaculture requires good water quality, the right amount of water and the right temperature. Only in this way can optimal growth conditions for fish be ensured.
Wastewater
Two main treatment steps are used to treat wastewater in aquaculture systems: mechanical filters such as the self-cleaning Hydrotech™ Drumfilters are used to remove solids larger than 60/10 microns, and biological water treatment is applied to eliminate carbon and nitrogen pollution, using AnoxKaldnesⓇ MBBR.
Water reuse
Our sustainable Recirculating Aquaculture System (RAS) reduces water consumption, reusing water through continual treatment and delivery to support a wide variety of species, including cold water, tropical, fresh and saltwater. This closed-loop fish-farming system allows up to 99% of the water to be reused, translating to much smaller water and carbon footprints and a reduced environmental impact.
Sludge
Sludge and waste from fish farming activities can be treated to minimize and mitigate any impact on the environment.
Aquaculture clients that trust Veolia
To produce certified sustainable salmon from its land-based salmon farm in the Swiss Alps, Swiss Alpine Fish must have control of its water consumption and discharge.
To achieve this objective, the company has invested in Veolia’s RAS2020™ aquaculture system.
Discover our water treatment technologies for the aquaculture industry
Based on the strong water treatment experience of our subsidiaries and their technologies, our sustainable aquaculture experts provide turnkey solutions, such as recirculating aquaculture systems, for all kinds of fish species, from fresh to seawater and cold to tropical water.
In the RAS2020, we create and maintain the optimal conditions to grow premium fish with a reduced need for antibiotics. Furthermore, we can treat the wastewater to minimise environmental impact and refine the sludge for potential energy use. RAS aquaculture is truly a sustainable solution for growing the food of the future.
