  1. 1. Idealised remediation scenario in two small-scale intersecting fractures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Agnes Zúniga Ekenberg; [2022]
    Keywords : ;

    Abstract : Analysis of mass transport in rock fractures has become increasingly important in underground storage of radioactive materials and remediation of polluted groundwater in fractured rock aquifers. Permeability of rock mass is regulated by present rock fractures, where flow is mainly through the fracture networks. READ MORE

  3. 2. Metal Removal Efficiency of Five Filter Media Intended for use in Road Stormwater Treatment Facilities

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Lovisa Lundgren; [2021]
    Keywords : Stormwater; Metal removal efficiency; Filter media; Dagvatten; Metallavskiljningskapacitet; Filtermaterial;

    Abstract : Roads, buildings, vehicles, and human activities cause spreading of pollutants, which partly end up in stormwater. The pollutant load contains solid particles of various size, hydrocarbons, organics, metals, nutrients, and microorganisms, which can have negative effects on water quality of surface-, coastal- and ground waters.

  4. 3. Treatment of dissolved metals in highway runoff water : Pilot-scale trial with four reactive filter media and sand filter

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Serena Bianchi; [2021]
    Keywords : stormwater treatment; metal removal; adsorption; reactive filter media; sand filtration; Petrit-T; Polonite; D-Rainclean; Filtralite-P; de-icing salt; pressure drop; filter clogging; rening av dagvatten; avl ̈agsnande av metaller; adsorption; reaktiva filterme- dier; sandfiltrering; Petrit-T; Polonite; D-Rainclean; Filtralite-P; avisningssalt; tryckfall; filterstoppning;

    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. Flow pattern analysis of a Surface Flow Constructed Wetland : Treating surface runoff and landfill leachate water from the Löt waste management site

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Max-Bernhard Alm; [2020]
    Keywords : Surface flow constructed wetland; flow pattern analysis; numerical model;

    Abstract : The waste management and recycling company, Söderhalls Renhållningsverk (SÖRAB) have constructed a surface flow wetland in order to treat surface runoff from the waste management site, Löt. The contaminated water passes several treatment steps until it reaches the wetland and a subsequent soil infiltration step. READ MORE

  6. 5. Factors controlling the sorption of Cs, Ni and U in soil : A statistical analysis with experimental sorption data of caesium, nickel and uranium in soils from the Laxemar area

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emilia Johansson; [2020]
    Keywords : correlation analysis; Kd values; partition coefficient; Pearson correlation; radionuclide; soil; sorption;

    Abstract : In the fall of 2006, soils from three small valleys in the Laxemar/Oskarshamn area were sampled. A total of eight composite samples were characterized for a number of soil parameters that are important for geochemical sorption and were later also used in batch sorption experiments. READ MORE
