  1. 21. Wastewater treatment with nanofiltration in pilot-scale

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Jane Quach; Safa al Basheer; [2018]
    Keywords : wastewater; nanofiltration; ultrafiltration; chemical precipitation; pilot-scale; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : During the spring semester 2018, an investigation about supplementary cleaning of the waste water at Dow Chemical site in Landskrona was done. Different water-based binders from acrylic monomers are produced by Dow and large amounts of water is used for such processes. READ MORE

  3. 22. Spatial Variation of THg and MeHg Stream Concentrations and Its Relation to TOC

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Maria Tranvik; [2017]
    Keywords : Mercury; organic matter; catchment characteristics; GIS; deforestation; Kvicksilver; organiskt material; avrinningsområdesfaktorer; GIS; skogsavverkning;

    Abstract : Mercury (Hg) which originates from global emissions to the atmosphere can deposit far away from the source. There is often a weak correlation between Hg deposition and concentrations in runoff, therefore catchment specific parameters might be of importance in controlling the amount of Hg ending up in watercourses and fish.

  4. 23. Impact of increased production on TOC to the Waste Water Treatment Plant : Piteå 750

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Johan Lundberg; [2017]
    Keywords : ;

    Abstract : Today there are strict demands regarding emissions to water and air from the Swedish industries. This degree project, conducted at Smurfit Kappa Piteå, will focus on the emissions of organic material in waste water from the paper mill. READ MORE

  5. 24. Long-term trends in bottom water chemistry of Swedish lakes

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

    Author : Jelena Rakovic; [2017]
    Keywords : hypolimnion; sediment; oxygen; dissolved organic carbon; phosphorus; ammonium; silica;

    Abstract : Long-term monitoring of lake water is essential for tracking local and long-range effects of anthro-pogenic pressure and to inform policy aiming at mitigating human environmental impacts. Swedish reference lakes are recovering from acidification; are subject to climate change and increasing inputs of terrestrial dissolved organic matter (DOM). READ MORE

  6. 25. 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
