Effluent water treatment from fish farms

Effluent water treatment from fish farms

Wastewater from fish farms and production plants constitutes pollutants that may harm the receiving water resources. Treatment of discharges is hence often a necessity to ensure sustainability of fish production facilities. Effluent treatment will typically constitute processes for removal of major pollutants such as organic matter, suspended solids, ammonia nitrogen and bacteria/virus. Ntesco offer a wide range of treatment solutions for these objectives. Typical unit processes may include: 

• Biological treatment 
• Solids removal 
• Disinfection 

Sludge treatment 

Sludge and waste from fish farm facilities typically comprises biomass from biological treatment, fish faeces, feed waste, dead fish and abattoir waste. Ntesco offers solutions for: 

• Storage 
• Stabilization 
• Hygienization 
• Dewatering 

Ntesco has developed a range of concepts for sludge handling at fish farms and fish processing sites. The different systems are adapted to each individual site based on quantity and quality of raw sludge, local regulations and transportation- and end user requirements. All of Ntesco’ sludge treatment systems focus on high quality, low energy and simple operation with low requirements for maintenance.
