Recirculating Aquaculture Systems - Veolia Water Solutions ...

Water conditioning in flow through systemsElevated CO 2concentrations and marginal O 2levels are the main challenge in flowthrough systems. This has a negative impact on fish welfare and growth rate. Withmore intensive and stable production, Krüger Kaldnes offers cost-effective systemsfor CO 2stripping and aeration.Effluent water treatment from fish farmsand abattoir wasteWastewater from fish farms and production plants constitutes pollutants thatmay harm the receiving water resources. Treatment of discharges is hence often anecessity to ensure sustainability of fish production facilities. Effluent treatmentwill typically constitute processes for removal of major pollutants such as organicmatter, suspended solids, ammonia nitrogen and bacteria/virus. Krüger Kaldnesoffers a wide range of treatment solutions for these objectives.Typical unit processes may include:▲▲Biological treatmentSolids removal▲ DisinfectionSludge treatmentSludge and waste from fish farm facilities typically comprises biomass from biologicaltreatment, fish faeces, feed waste, dead fish and abattoir waste.Krüger Kaldnes offers solutions for:▲ Storage▲ Stabilization▲ Hygienization▲ DewateringKrüger Kaldnes has developed a range of concepts for sludge handling at fishfarms and fish processing sites. The different systems are adapted to eachindividual site based on quantity and quality of raw sludge, local regulations andtransportation- and end user requirements. All of Krüger Kaldnes’ sludge treatmentsystems focus on high quality, low energy and simple operation with lowrequirements for maintenance.Other processes provided in Kaldnes TM RAS plantsmay include oxygenation, ozonation, UV disinfection,CO 2removal, N 2removal and alkalinisation.Kaldnes TM RAS provides highly compact and energyefficient solutions with focus on easy operation and lowmaintenance requirements.
