Effects of reduced organic matter loading through membrane filtration on the microbial community dynamics in recirculating aquaculture systems (RAS) with Atlantic salmon parr (Salmo salar)
Fossmark, Ragnhild Olsen; Vadstein, Olav; Rosten, Trond Waldemar; Bakke, Ingrid; Koseto, Deni; Bugten, Anette Voll; Helberg, Gaute Alexander Nedberg; Nesje, Jenny; Jørgensen, Niels O.G.; Raspati, Gema Sakti; Azrague, Kamal; Østerhus, Stein Wold; Attramadal, Kari (Journal article; Peer reviewed, 2020-07-15)A key challenge in recirculating aquaculture systems (RAS) is the accumulation of particulate organic matter, especially the fine and colloidal fraction due to low removal efficiency of today's technology. The supply of ... -

Experimental investigation of simultaneous nitrification-denitrification and phosphorus removal in pilot-scale sequencing batch moving bed biofilm reactors (SB-MBBRs)
Fanta, Abaynesh Belay; Sægrov, Sveinung; Azrague, Kamal; Østerhus, Stein Wold (Peer reviewed; Journal article, 2024)Sequencing batch moving bed biofilm reactors have been widely used in commercial wastewater treatment facilities for organic carbon and nitrogen removal. However, these reactors can remove low phosphorus (P) levels. ... -
Struvite crystallization by using raw seawater: Improving economics and environmental footprint while maintaining phosphorus recovery and product quality
Shaddel, Sina; Grini, Tonje; Ucar, Seniz; Azrague, Kamal; Andreassen, Jens-Petter; Østerhus, Stein Wold (Peer reviewed; Journal article, 2020)Seawater, as an alternative magnesium source, has the potential to improve the overall economics and environmental footprint of struvite production compared to the use of pure magnesium salts. However, the dilution effect ...
