  1. 1. New applications of fluorescence spectroscopy for monitoring drinking water disinfection and distribution

    Författare :Masoumeh Heibati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dissolved organic matter; UV disinfection; Fluorescence spectroscopy; drinking water; distribution network;

    Sammanfattning : The task of providing safe drinking water requires proper monitoring of water quality and treatment performance from source to tap. Accordingly, the demand for online monitoring is increasing both at treatment plants and within distribution networks. LÄS MER

  3. 2. Aspects of historical data and health criteria for drinking water network replacement strategies

    Författare :Annika Malm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pipe rehabilitation; water distribution network; cost-benefit analysis; Pipe replacement; leakage control; lifetime distribution; pipe failure; health risk; strategic planning; asset management;

    Sammanfattning : The drinking water distribution network represents a major proportion of the investments and capital assets of a water utility. Consequently, qualified insight into future replacement needs provides water utilities with a foundation for financial planning. LÄS MER

  4. 3. Applications of natural organic matter optical properties for assessing drinking water disinfection and distribution

    Sammanfattning : The task of providing safe drinking water requires proper monitoring of water quality and treatment performance from source to tap. Accordingly, the demand for online monitoring is increasing both at treatment plants a nd within distribution networks. LÄS MER

  5. 4. Assessing the health consequences of deficiencies in water distribution networks: a basis for future network management

    Författare :Victor Vinas; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; QMRA; risk management; distribution network; microbial risk; epidemiological studies;

    Sammanfattning : Drinking water distribution networks are susceptible to incidents that may contaminate the drinking water being served to the population. Five major risks that can impact negatively the health of consumers have been identified by a literature study: intrusion, cross-connections and backflows, unhygienic repairs or maintenance works, inadequate management of storage reservoirs and biofilms.

  7. 5. 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.
