Optimized In-Line Denitrification for Recirculating Aquaculture Systems (OptiDeNit)

Offentlig prosjektsammendrag

Traditional aquaculture systems (sea-based and flow-through) face growing challenges of environmental pollution due to nutrient discharge, lack of space along coastlines and freshwater consumption. Several countries, especially Norway, have taken political initiatives to promote land-based recirculating aquaculture systems (RAS) as a solution for promoting aquaculture production while limiting environmental harm. RAS is a fast growing industry, expected to reach $700M in 2027 with a CAGR of 15%, and forecasted to represent 30% of all aquaculture production by 2030, with large growth due to export of water treatment technology to countries in the Asia-Pacific region. In order for RAS technology to become sustainable, full control of water quality parameters and the optimization of rearing conditions with lowest environmental impact are crucial because water is becoming scarce. Our goal with this project is to reduce today's water requirements of RAS facilities.
