    Abstract : The increasing highway traffic is leading to higher and higher levels of pollutants in the stormwater, such as suspended solids, metals, oils, nutrients and PAH. This runoff water causes the degradation of water bodies quality, leading to increased interest in the treatment of highway runoff for the removal of contaminants. READ MORE

  5. 4. Avskiljning av uran från dricksvatten med reaktiva filter

    University essay from SLU/Dept. of Soil Sciences

    Author : Ellinor Dässman; [2008]
    Keywords : uran; reaktiva filter; järnoxid; bergsborrade brunnar; jämviktsmodellering; Visual Minteq;

    Abstract : Water is our most important provision and its quality is above all dependent on the geological conditions in the area from where it is extracted. Due to geological properties there are certain areas with an elevated risk of high uranium levels in the ground water, which in turn constitutes a risk for human health. READ MORE

  6. 5. Hydrauliken i Ångersjöns fosforfällor : bestämning av flödesvägar och åtgärdsförslag för optimal fosforbindning vid avloppsrening med reaktiva filter

    Author : Ellinor Jansson; [2008]
    Keywords : fosforrening; Ångersjön; filtermaterial;

    Abstract : Discharge of untreated wastewater leads to unnaturally high levels of nitrogen and phosphorus in rivers, lakes and the sea, which results in unbalanced ecosystems with eutrophication and lack of oxygen. Part of the phosphorus in surface waters is coming from on-site wastewater treatment from scattered households with unsatisfactory purification. READ MORE
