  1. 1. Phosphorus and Nitrogen Removalin Modified Biochar Filters

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Ylva Stenström; [2017]
    Keywords : biochar; modified biochar; phosphorus filter; wastewater; batch adsorption experiment; nitrogen filter; COD; Tot-P; Tot-N; biokol; impregnerat biokol; fosforfilter; avloppsvatten; skakexperiment; kvävefilter; COD; Tot-P; Tot-N;

    Abstract : Onsite wastewater treatment systems in Sweden are getting old and many of them lack sufficient phosphorus, nitrogen and organic carbon reduction. Biochar is a material that has been suggested as an alternative to the common sand or soil used in onsite wastewater treatment systems. READ MORE

  3. 2. Heavy metal removal and water treatment using Upsalite

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Philip Erenbo; [2017]
    Keywords : Upsalite; lead; cadmium; nickel; MgO3; heavy metal; water treatment;

    Abstract : Ion exchange reactions between Upsalite, a mesoporous magnesium carbonate, and metal ions of cadmium, lead and nickel have been studied to evaluate the capacities of Upsalite as a water treatment agent. Uptake capacity and reaction kinetics have been evaluated using a batch experiment and atomic absorption spectroscopy. READ MORE

  4. 3. Virus removal during artificial groundwater recharge and the effects of organic matter : Tunåsen infiltration basins, Uppsala, Sweden

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

    Author : Lisanne Hölting; [2015]
    Keywords : drinking water; artificial groundwater recharge; bacteriophages; organic matter; adsorption;

    Abstract : Die Verunreinigung von Trinkwasser mit pathogenen Mikroorganismen kann zu epidemischen Krankheitsausbrüchen führen und stellt daher weltweit ein Risiko für die menschliche Gesundheit dar. Oberflächengewässer sind im Gegensatz zu Grundwasser anfälliger für Verunreinigungen. READ MORE

  5. 4. Evaluation of the Removal Efficiency of Perfluoroalkyl Substances in Drinking Water

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sophie Englund; [2015]
    Keywords : per- and polyfluoroalkyl substances; PFASs; anion exchange; activated carbon; drinking water; removal efficiency;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are chemicals that have been used for over 50 years. They are both hydrophobic and hydrophilic, which make them useful in a wide range of products, both in the domestic and industrial market. Recently, the global attention on PFASs has increased due to their possible harmful health effects on humans. READ MORE

  6. 5. Effects of pH and Cation Composition on Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil Particles
