  1. 1. Investigations of the microbial diversity and dynamics in activated sludge using molecular methods

    Detta är en avhandling från Chalmers University of Technology

    Författare :Johan Fredriksson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treatment; activated sludge; microbial ecology; population dynamics; Bacteria; Archaea; 16S rRNA; terminal restriction fragment length polymorphism;

    Sammanfattning : Wastewater treatment is necessary to reduce the health risks and environmental impacts associated with discharge of untreated wastewater. The most common way to treat wastewater in wastewater treatment plants is through the activated sludge process. LÄS MER

  2. 2. Enzymatic treatment of wastewater sludge. Sludge solubilisation, improvement of anaerobic digestion and extraction of extracellular polymeric substances

    Detta är en avhandling från Pure and Applied Biochemistry, Lund University

    Författare :Joanna Wawrzynczyk; Lunds universitet.; Lund University.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollution control; Environmental technology; sludge treatment; wastewater activated sludge; Proteins; enzymology; Proteiner; enzymologi; cation-binding agents; mass reduction; lectins; extracellular polymeric substances; enzymes; enzymatic activity; anaerobic digestion; biogas; Miljöteknik; kontroll av utsläpp; Biotechnology; Bioteknik;

    Sammanfattning : The processing and disposal of sludge from wastewater treatment plants is an important topic of increasing environmental, ecological, technological, economic and social concern. The large amounts of sludge produced represent an urgent problem today, new treatment methods being very much needed. LÄS MER

  3. 3. Anaerobic treatment of wastewater in a UASB reactor

    Detta är en avhandling från Stockholm : KTH

    Författare :Larisa Korsak; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic treatment; UASB; granular biomass; methanogenic activity; modelling; axial dispersion; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Sammanfattning : The anaerobic treatment of waste water has been studied with an emphasis on the Up- flow Anaerobic Sludge Blanket (UASB) reactor. A model to describe the processes occurring in a UASB reactor was developed and an experimental study of the anaerobic wastewater treatment systems in Nicaragua was also performed. LÄS MER

  4. 4. Microbial communities in anammox and nitrifying biofilms

    Detta är en avhandling från Göteborg : Department of Chemistry and Molecular Biology, Faculty of Science, University of Gothenburg

    Författare :Carolina Suarez; Göteborgs universitet.; Gothenburg University.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofilms; AOB; partial nitritation anammox; nitrification; wastewater;

    Sammanfattning : Excess of nitrogen in water bodies causes eutrophication. One important source of nitrogen is the effluent from wastewater treatment plants (WWTPs). Nitrogen in wastewater is most commonly removed by nitrification-denitrification. LÄS MER

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

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Jesper Olsson; Mälardalens högskola.; [2018]
    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.
