  1. 1. Treatment of textile wastewaters using combinations of biological and physico-chemical methods

    Författare :Maria Jonstrup; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; azo dyes; anaerobic-aerobic treatment; white rot fungi; laccase; photocatalysis; photo-Fenton;

    Sammanfattning : Considerable amounts of water and chemicals are used in the textile industry, and the presence of dyes in the wastewater is a problem of environmental concern. Synthetic dyes are designed to resist light, water and chemicals to improve the quality of the textiles; however, these properties also contribute to their persistence in the environment. LÄS MER

  3. 2. Production of polyhydroxyalkanoates in biological treatment of industrial wastewaters

    Författare :Simon Bengtsson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyhydroxyalkanoates; mixed cultures; glycogen accumulating organisms GAO ; feast and famine; acidogenic fermentation; activated sludge;

    Sammanfattning : In search of more environmentally friendly polymer materials, polyhydroxyalkanoates (PHAs) have been considered as promising candidates. PHAs exhibit a broad range of material properties, can be produced from renewable resources and are completely biodegradable. LÄS MER

  4. 3. Enhanced Biological Phosphorus Removal - Carbon Sources, Nitrate as Electron Acceptor, and Characterisation of the Sludge Community

    Författare :Magnus Christensson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; nitrate; carbon source; PAO; polyphosphate accumulating organisms; enhanced biological phosphorus removal; EBPR; characterisation; Biotechnology; Bioteknik;

    Sammanfattning : Enhanced biological phosphorus removal (EBPR) was studied in laboratory scale experiments as well as in a full scale EBPR process. The studies were focused on carbon source transformations, the use of nitrate as an electron acceptor and characterisation of the microflora. LÄS MER
