  4. 2. On the determination and application of local filtration properties

    Author : Peter Sedin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : Filtration is a mechanical unit-operation used for the separation of liquid and solid. In this work, the three sub-operations cake build-up, expression and washing have been studied. One difficulty often encountered in the design of filtration equipment is that the materials being filtered form more or less compressible filter cakes. READ MORE

    Abstract : As the demand for carbon dioxide neutral energy sources increases, forestry becomes more intensive. Entire trees are removed from the felling sites threatening the nutrient balance of the forest soils. READ MORE

  6. 4. Leaching of Polycyclic Aromatic Hydrocarbons Using a Column Method

    Author : Anja Enell; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Naturvetenskap; Chemical technology and engineering; Natural science; Miljöstudier; Environmental studies; coal tar; PAHs; desorption; soil; combustion residues; remediation; availability;

    Abstract : Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants of great environmental concern, due to their toxicity, carcinogenicity and long persistence in the environment. To determine the potential risk associated with PAHs released from contaminated soil or waste materials, knowledge is required on the leachable concentrations of PAHs and the amounts available for release.
