    Sammanfattning : Three types of wastewater ponds in subarctic climates were investigated, each of them highly dependent on microalgae. They were fellingsdams, i.e. LÄS MER

  3. 22. Indigenous microalgae-activated sludge cultivation system for wastewater treatment

    Författare :Anbarasan Anbalagan; Emma Nehrenheim; Carl-Fredrik Lindberg; Sebastian Schwede; Raquel Labrero; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The municipal wastewater is mainly composed of water containing anthropogenic wastes that are rich in nutrients such as carbon, nitrogen and phosphorous. The cost for biological treatment of wastewater is increasing globally due to the population growth in urban cities. LÄS MER

  4. 23. Communities of microalgae and bacteria in photobioreactors treating municipal wastewater

    Författare :Ivo Krustok; Monica Odlare; Emma Nehrenheim; Jaak Truu; Catherine Legrand; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Everyone who uses water produces wastewater. This inevitability creates several problems that increase with the growth of the population and industry. LÄS MER

  5. 24. Nutrient Recovery as an Added Benefit to Harvests of Photosynthetic Marine Biomass : A Holistic Systems Perspective on Harvesting Marine Microalgae, Cyanobacteria, and Macroalgae

    Författare :Joseph Pechsiri; Fredrik Gröndahl; Maria Malmström; Angela Wulff; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Industrial Ecology; Industriell ekologi;

    Sammanfattning : As a result of increasing environmental burdens from anthropogenic activities andresource scarcity, interest for the development of solutions utilizing photosyntheticmarine biomass has also been increasing in both academia and industries. Medium tolarge scale production and harvest of photosynthetic marine biomass have beenpracticed to achieve numerous services, including improving tourism industries,production of biofuels, and production of food/feed.

  7. 25. Autotrophic and heterotrophic culture of Nordic microalgae in wastewater for lipid production

    Författare :Jean Claude Nzayisenga; Anita Sellstedt; Francesco G. Gentili; Christiane Funk; Ashton Keith Cowan; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : It is well established that society’s main means for producing energy, the combustion of fossil fuels, is unsustainable and contributes to global warming. Microalgae have high potential for the production of biodiesel and energy source that can at least partially replace fossil fuels. LÄS MER
