Fish farming

Fish Farming

Wastewater from fish farms contains pollutants that may harm the receiving water resources. This is one reason why treatment of discharges is a necessity to ensure the sustainability of fish production facilities.

To advance the capabilities of present and future aquaculture applications, wastewater from these facilities may also be recycled in RAS (Recirculating Aquaculture Systems) plants where up to 99% of the total wastewater flow may be reused.

Wastewater treatment for aquaculture will typically consist of processes for removal of major pollutants such as organic matter, suspended solids, ammonia nitrogen, dissolved gases and bacteria/virus.

Typical process units may include:

  • Biological treatment
  • Solids removal
  • Disinfection
