  1. 11. Impact of different catchments on the Brownification of Lake Bolmen

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Kaela Chileshe; [2020]
    Keywords : Brownification; dissolved organic carbon DOC ; Iron Fe ; water colour; landscapes; climate change;

    Abstract : Increased DOC and Fe concentrations from terrestrial landscapes has led to the browning of boreal surface waters. The negative societal and ecological impacts of brownification are increased cost of water purification, increased presences of algae and cyanobacteria, loss of ecosystem services and reduced recreational value.

  3. 12. 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

  4. 13. 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

  5. 14. Dynamics of Humic Substance in Bolmen Lake, Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Muluneh Ertiro Tumdedo; [2010]
    Keywords : Bolmen Lake; Temperature; Discharge; Dissolved Organic Matter; Water Colour; Storån River.; Humic Substance; Precipitation; Technology and Engineering;

    Abstract : Humic substance (HS) in natural water is a complex compound, and causes problems in the production and distribution of drinking water. In addition to the adverse effect of HS on the aesthetic of water quality, it also causes a health problem. The objective of this thesis was to analyse the dynamics of HS in Bolmen lake. READ MORE

  6. 15. Resistivity and IP measurements at the Bolmen Tunnel and Ådalsbanan, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Miriam Cegrell; Jimmy Mårtensson; [2008]
    Keywords : resistivity; induced polarisation IP ; geophysics; geology; Bolmen; Ådalsbanan; resistivitet; inducerad polarisation IP ; geofysik; geologi; Earth and Environmental Sciences;

    Abstract : In all tunnel construction projects geophysical methods are important as a foundation for engineering geological conceptual models. Detailed information about the condition and the physical properties of rocks at depth is desirable, and geophysical methods have the potential to exploit these properties. READ MORE
