  1. 1. Water Governance : Policy, Politics and Regulation in Honduras

    Författare :Patricia Phumpiu; Jan-Erik Gustafsson; Cecilia Scharp; Jose Esteban Castro; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water Governance; Honduras; Institutions; Policy; Politics; Regulatory Governance; Regulatory State; Water engineering; Vattenteknik;

    Sammanfattning : Water governance exerts an impact on the socio-politic life of Honduras. For instance, the new legal framework changes institutions. New water organisations are created, and new processes and proceedings are proposed. LÄS MER

  3. 2. Assessing and optimizing biofilter performance in drinking water treatment

    Författare :Nashita Moona; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-scale biofilters; sterilization.; optical properties; Biofilter; dissolved organic matter; treatment optimization; drinking water;

    Sammanfattning : Biological filtration is a widely used treatment barrier in drinking water treatment plants to ensure the biological stability of treated water in distribution systems. Biofilters remove particulate and dissolved organic matter (DOM) and biodegradable organic matter from water. LÄS MER

  4. 3. Innovative treatment technologies for PFAS-contaminated water - Utilizing foam partitioning and exploring electrochemical oxidation

    Författare :Sanne Smith; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The presence of per- and polyfluoroalkyl substances (PFAS) in the aquatic environment has become a global cause for concern. PFAS are persistent anthropogenic chemicals, and certain PFAS are known to be mobile, bioaccumulative and toxic. LÄS MER

  5. 4. Core Level Spectroscopy of Water and Ice

    Författare :Dennis Nordlund; Anders Nilsson; Martin Wolf; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-ray adsorption spectroscopy; photoemission spectroscopy; x-ray photoelectron spectroscopy; platinum; x-ray emission spectroscopy; density functional theory; hydrogen-bonded; H-bond; water; ice; electronic structure; excited state dynamics; proton dynamics; water adsorption; liquid water; Physics; Fysik;

    Sammanfattning : A core level spectroscopy study of ice and water is presented in this thesis. Combining a number of experiments and spectrum calculations based on density functional theory, changes in the local valence electronic structure are shown to be sensitive to the local H-bonding configurations.

  7. 5. Water powered percussive rock drilling : process analysis, modelling and numerical simulation

    Författare :Göran Tuomas; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : This thesis is devoted to problems, processes and systems related to the recently developed water powered percussive rock drilling method. The technology, which uses ordinary water to drive down-the-hole hammers, has been used to produce more than 6 million meters of blast holes within the mining industry. LÄS MER
