  1. 1. The Prevalence of Radioactivity in a Number of Non-Nuclear Industries

    Författare :Torbjörn Gäfvert; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kärnfysik; Nuclear physics; zircon; ceramics industry; thorium; TIG welding; waterworks; calcium chloride; dicalcium phosphate; phosphate industry; non-nuclear industries; TENORM; Natural radioactivity; NORM;

    Sammanfattning : Four different non-nuclear industries have been investigated regarding the presence of radioactive elements, with the focus on natural radioactivity. The aim of the studies was to investigate the flow of radionuclides in the processes and/or to estimate doses to exposed workers. LÄS MER

  3. 2. The occurrence of disinfection by-products in four Swedish drinking waterworks

    Författare :Muhammad Jamshaid Ashiq; David Bastviken; Henrik Kylin; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Disinfection by-products (DBPs) are unwanted, potentially toxic compounds formed when drinking water is disinfected with chemical disinfectants such as chlorine or chloramine. The levels of DBPs produced depends on parameters, such as levels of natural organic matter (NOM) and the nature and concentration of chemical disinfectant used. LÄS MER

  5. 4. Climate Change Adaption of Waterworks for Browning Surface Waters : Nano- and Ultrafiltration Membrane Applications for Drinking Water Treatment

    Författare :Alexander Keucken; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural organic matter NOM ; drinking water; ultrafiltration; nanofiltration; autopsy; modelling;

    Sammanfattning : Natural organic matter (NOM) is found in all surface, ground, and soil waters. During recent decades, reports worldwide show a continuing increase in the color and NOM of the surface water, which has an adverse effect on drinking water purification. For several practical and hygienic reasons, the presence of NOM is undesirable in drinking water. LÄS MER

  7. 5. Artificial recharge of groundwater for public water supply : potential and limitations on boreal conditions

    Författare :Cristina Frycklund; KTH; []
    Nyckelord :;

    Sammanfattning : It is motivated by the intentions of Agenda 21 to findalternatives to the increasing dependence on chemical treatmentin the production of public water. Conventional waterworkscommonly include chemicals for removal of organic compounds,for reduction of corrosiveness and for disinfection. LÄS MER
