    Sammanfattning : Dissolved Air Flotation (DAF) is a separation process in water and wastewater treatment. The removal function is based on reducing the density of the particle by producing aggregates of the particles and added micro-bubbles of air, thus lifting the aggregates to the water surface, where they can be removed as sludge.

  5. 4. Start-up and operational strategies for deammonification plants : - a study with one-stage moving bed biofilm reactors treating reject water

    Författare :Linda Kanders; Eva Thorin; Susanne Lackner; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : To limit eutrophication, wastewater treatment plants use biological methods to convert degraded nitrogen to nitrogen gas. Deammonification, or partial nitritation in combination with anammox, has been shown to be an energy efficient process. LÄS MER

  7. 5. Co-digestion of microalgae and sewage sludge - A feasibility study for municipal wastewater treatment plants

    Författare :Jesper Olsson; Eva Thorin; Sebastian Schwede; Emma Nehrenheim; Raúl Muñoz Torre; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; Anaerobic digestion; dewaterability; BMP-experiments; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The increased emissions of anthropogenic greenhouse gases over the last 100 years is the reason for the acceleration in the greenhouse effect, which has led to an increase of the globally averaged combined land and ocean surface temperature of 0.85 °C between 1880 and 2012.
