## 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.
