1. 1. Uncharted Waters : Non-target analysis of disinfection by-products in drinking water

   Författare :Anna Andersson; David Bastviken; Henrik Kylin; David Reckhow; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water treatment technologies; chemical disinfection; FT-ICR MS; bioassays; Vattenreningstekniker; klor; kloramin; FT-ICR MS; effektbaserad analys;

   Sammanfattning : Disinfection by-products (DBPs) are potentially toxic compounds formed when drinking water is treated with disinfectants, such as chlorine or chloramine. A large proportion of the exposure to DBPs is still unknown and the health risks observed through epidemiological studies cannot be explained by DBPs known today. LÄS MER

3. 2. 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

4. 3. 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. Tracking changes in dissolved natural organic matter composition : evaluating drinking water production using optical and molecular level tools

   Författare :Elin Lavonen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : During the last decades, the abundance of dissolved organic matter (DOM), a complex heterogeneous mixture of organic compounds, has increased in many surface waters in Northern Europe and North America. Surface waters are widely used as raw water sources for drinking water production. LÄS MER

7. 5. Partial renewal of granular activated carbon filters for improved drinking water treatment

   Författare :Nashita Moona; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofiltration; Drinking water treatment; Spectroscopic properties; Granular activated carbon filter; Natural organic matter; Online monitoring; Fluorescence;

   Sammanfattning : Drinking water is widely collected from surface water sources. In these water sources, both the quantity and quality of natural organic matter (NOM) have been affected around the world during the last decades, especially in Northern Europe and North America. LÄS MER
