    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Frida Ekman; [2021]
    Keywords : Ekoln; Natural organic matter NOM ; Total organic matter TOC ; Colour; degradation; sedimentation; photooxidation; PFAS; MIKE 3 FM; Ekoln; naturligt organiskt material NOM ; totalt organiskt kol TOC ; färg; nedbrytning; sedimentation; foto-oxidation; PFAS; MIKE 3 FM;

    Abstract : Societies are facing great challenges with obtaining a good quality and quantity of drinking water in the context of climate change. Increases in natural organic matter (NOM) and per- and polyfluoroalkyl substances (PFAS) have been observed in lakes and drinking water the past years, which is of great concern for water treatment plants in Sweden.

  2. 2. Environmental transformations of Manganese and Manganese oxide nanoparticles

    University essay from KTH/Materialvetenskap

    Author : Lundberg Annie; [2020]
    Keywords : ;

    Abstract : Engineered nanoparticles (NPs) are produced in increased quantities. Due to this increase, itis vital to understand the full lifecycle and fate of these NPs to prevent any possible environmental stress. READ MORE

  3. 3. Comparison and optimization of removal of natural organic carbon from raw water with ultrafiltration in pilot scale experiments

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Tamara Kristin Voigtländer; [2020]
    Keywords : Dissolved Organic Carbon; raw water quality; online coagulation; high-frequency sonde; drinking water treatment;

    Abstract : The removal of natural organic matter (NOM) from Swedish surface waters has become a large challenge for drinking water treatment plants (DWTP), as NOM content has been rising in surface waters all over Northern Europe. In the last decade, membrane technologies, often combined with coagulation, have become more and more common. READ MORE

  4. 4. Fractionation of NOM in water from the treatment process at Ringsjöverket

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Stina Karlsson; [2018]
    Keywords : water engineering; environmental engineering; avloppsteknik; Technology and Engineering;

    Abstract : During the last decades, increased concentrations of natural organic matter (NOM) and colour of surface waters have been reported from northern Europe and North America. Since surface waters are widely used for drinking water production this development has been problematic for drinking water producers. READ MORE

  5. 5. Membrane screening to identify optimal properties when separating organic matter from Bolmen water

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Olivia Söderman; [2017]
    Keywords : natural organic matter; ultrafiltration; nanofiltration; drinking water; membrane technology; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

    Abstract : In many places across the northern hemisphere, drinking water treatment plants (WTPs) need to avert the effects of deteriorating quality in surface water sources caused by increasing lev-els of natural organic matter (NOM). The two major factors responsible for this phenomenon, also called brownification, are the greenhouse effect and changes in soil acidification. READ MORE
