Aquaculture

Efficient filtration solutions for sustainable fish farming

Hydrotech filters are highly flexible and can be fitted with screens from 10 – 2,000 micronmeter. As an example, they are successfully used for:

• Recirculated system (RAS) or flow-through systems
• Intake water
• Effluent water
• Filters for removing sea lice from water on well boats
• Algae filtration
• Aquaponics 
  (Aquaponics refers to a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants, involving nitrifying bacteria for converting ammonia into nitrates.)

Using Hydrotech microscreens in a fish farm can remove up to:

• 80% of total BOD
• 85% of total phosphorus
• 90% of the solids in the water

This releases environmental pressure from our natural resources, guarantees animal well-being, and contributes to the safety of our food chain.

Water quality control will become key to ensuring more sustainable fish farming while the world population increases.
