  2. 1. Simulation and Optimization of Recirculating Aquaculture Systems

    Author : Simon Pedersen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dynamic modelling; optimization; biofilter; wastewater treatment; Recirculating aquaculture;

    Abstract : Recirculating aquaculture -- intensive fish farming with water treatment and reuse -- has great potential as a method for sustainable food production. Benefits over traditional aquaculture include opportunities to reduce nitrogen emissions to water, control of temperature, salinity and pH, reduced environmental impact of escapes and better protection against e.

  5. 3. Adsorption of dissolved organic matter in aquatic ecosystems : Effects on composition and reactivity

    Author : Marloes M. Groeneveld; Lars Tranvik; Dolly Kothawala; Suzanne Tank; Uppsala universitet; []
    Keywords : dissolved organic matter; DOM; carbon; aquatic; adsorption; mineral particles; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Inland waters receive organic matter from terrestrial ecosystems and in situ production. In transit from land to the ocean, dissolved organic carbon (DOC) may be mineralised to inorganic forms (CO2 and CH4) by microbial degradation and photodegradation. READ MORE

  6. 4. Nitrogen Removal in Created Wetlands : Considerations – Challenges – Possibilities

    Author : Josefin E. Nilsson; Antonia Liess; Stefan Weisner; Eva Lindström; Jennifer Tank; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecosystem services; eutrophication; constructed wetlands; agricultural runoff; denitrification; wetland multifunctionality; climate change; nutrient retention; vegetation; hydrology; greenhouse gas emissions; biodiversity; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Created wetlands in agricultural landscapes deliver a multitude of ecosystem services, one of which is the removal of nitrogen (N) from water to reduce eutrophication. Wetland N removal, primarily through denitrification, is influenced by various factors. READ MORE

  7. 5. Dissolved Air Flotation

    Author : Mia Bondelind; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; two- and three-dimensional; Dissolved Air Flotation DAF ; aggregation model; Computational Fluid Dynamics CFD ; field study; surface forces; turbulence; single and multiphase flow;

    Abstract : Dissolved Air Flotation (DAF) is a well-established treatment method for water containing low density particles. The density-driven process is operated by the injection of water saturated with air under high pressure. At the pressure reduction microscopic air bubbles are formed. READ MORE
