  1. 6. Development of a Risk-Based Decision Model for Prioritizing Microbial Risk Mitigation Measures in Drinking Water Systems

    Författare :Viktor Bergion; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; quantitative microbial risk assessment; microbial risks; pathogens; water quality modelling; drinking water system; cost-benefit analysis; decision support;

    Sammanfattning : Risk management of drinking water systems is crucial since our society relies on these systems to be robust and sustainable to supply safe drinking water now and to future generations. Pathogens may spread in drinking water systems and cause waterborne outbreaks resulting in human suffering and large costs to the society. LÄS MER

  3. 7. 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

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

    Författare :Masoumeh Heibati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; assimilable organic carbon.; Optical properties; disinfection by-products; drinking water; UV disinfection; dissolved organic matter; 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 a nd within distribution networks. LÄS MER

  5. 9. Basin-scale change in water availability and water quality under intensified irrigated agriculture

    Författare :Rebecka Törnqvist; Jerker Jarsjö; Marcel van der Perk; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Irrigation; Hydrology; Land-use change; Basin-scale; Central Asia; Aral Sea; Semi-arid; Return flow; Water saving; Health risk; Water quality; Surface water; Groundwater; Nitrogen; Attenuation; Recirculation; Climate change; Physical Geography; naturgeografi;

    Sammanfattning : Changes in land use and water use can greatly impact the cycling of water and water-borne substances. Increased redistribution of river water to irrigated fields can cause enhanced evapotranspiration and decreased river discharge. LÄS MER

  7. 10. Application of indigenous materials in drinking water treatment

    Författare :Herbert Mpagi Kalibbala; Bengt Hultman; Joaquin Martinez; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coagulant aid; drinking water treatment; dual media filtration; Moringa oleifera; primary coagulant; trihalomethanes; volcanic ash; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : Volcanic ash and Moringa oleifera (M. oleifera) were investigated as indigenous materials for drinking water treatment based on problems identified at Kampala and Masaka water treatment plants in Uganda. LÄS MER
