A model for predicting alkalinity, pH, and CO2 levels in a flow-thru or recirculation aquaculture system independent of salinity
(Master thesis, 2018)Carbon dioxide is one of the limiting factors for construction of recirculation aquaculture system in the fish farming today. The level of carbon dioxide in the water heavily depends on fish metabolism and water chemical ... -
CO2 Removal in Column Aerator
(Master thesis, 2020)Carbon dioxide (CO2) removal has been an important water treatment stage in recirculating aquaculture system (RAS) because of the intensive fish load in land-based fish farm. Higher levels of CO2 12 mg/L were reported to ... -
Comparing particle removal in RAS farms
(Master thesis, 2020)Particle removal is an important treatment step in recirculating aquaculture system (RAS) for good fish health. This study compares the RAS in MOWI Fjæra and Bremnes Seashore Trovåg to see how well they perform in particle ... -
Finpartikler i RAS-system
(Master thesis, 2018)Mekanismene som fører til dannelse av finpartikler i RAS-anlegg er ikke helt forstått og heller ikke undersøkt i stor grad. Akkumulering av finpartikler er et resultat av hva som blir tilført (Fôr og avføring) og omdanning ... -
Particle size distribution of suspended solids in a commercial recirculating aquaculture system
(Master thesis, 2014-09-16)For the understanding of solids characteristic in RAS, the particle size distribution (PSD) of the suspended solids (SS) is a valuable tool. This study evaluates the PSD of the SS in an industrial RAS smolt farm in Norway. ... -
The startup process for moving bed bio-reactors (MBBR) in freshwater recirculating aquaculture systems (RAS) within the Norwegian aquaculture industry
(Master thesis, 2013-03-26)Recirculating aquaculture system (RAS) technology is becoming increasingly popular in today’s growing aquaculture industry, as it provides further expansion on already limiting good freshwater resources in a controllable ... -
Utslippsregnskap for COD, TN og TP i avløp fra småskala RAS med regnbueørret : Årungen som alternativ resipient
(Master thesis, 2015-07-31)Senter for fiskeforsøk ved Norges miljø- og biovitenskapelige universitet er et småskala landbasert oppdrettsanlegg for forskningsformål. Senteret blir i dag driftet som et resirkulerende akvakultursystem (RAS), og ønsker ... -
Varieties in discharge of nutrient from land-based aquaculture freshwater facilities : flow-through system vs recirculating aquaculture system
(Master thesis, 2020)Salmon farming is a large and still growing industry in Norway. Like all industries that utilize a country’s natural resources, will lack of focus on the environmental impact potentially lead to negative consequences. To ...
