  1. 1. Treatment of Metals in Highway Runoff Water : Comparison of green infrastructures and filter material for stormwater treatment

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Fanny von Matérn; [2023]
    Keywords : Road runoff; heavy metals; constructed wetland; stormwater pond; vegetated filterstrip; vegetated swale; sandfilter; reactive filter material; Vägdagvatten; tungmetaller; anlagd våtmark; dagvattendam; översilningsyta; svackdike; sandfilter; reaktiva filtermaterial;

    Abstract : Highway runoff transport high concentrations of heavy metals. As climate change affect the environment with for example increased storm events, the treatment of road runoff becomes more important. READ MORE

  3. 2. 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

  4. 3. Electron Assisted Growth of h-BN on Gr/Ir(111)

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Virginia Boix De La Cruz; [2018]
    Keywords : Two-dimension materials; 2D; Graphene; hexagonal Boron Nitride; Growth; CVD; STM; XPS; Physics and Astronomy;

    Abstract : Stacked heterostructures of two-dimensional (2D) materials are emerging as promising building blocks for a wide range of applications. These devices, which range from tunneling transistors to light-emitting diodes, use the properties of 2D materials that are not accessible by their bulk counterparts. READ MORE

  5. 4. Inhibition of phosphorus release from sediments of Lake Erhai through argon oxygen decarburisation slag (AOD) and electric arc furnace slag (EAF) capping.

    University essay from KTH/Mark- och vattenteknik

    Author : Linda Lindholm; [2016]
    Keywords : ;

    Abstract : The effects of eutrophication in lakes and the open seas has been largely the result of phosphorus (P) that accumulate in the sediment. Eutrophication occurs mainly in the waters in densely populated coastal areas and agricultural dominated areas and occurs when an excess of nutrients reach the soil and water. READ MORE

  6. 5. Evaluation of sorption behavior of two reactive filter materials using dual column laboratory investigation.

    University essay from KTH/Mark- och vattenteknik

    Author : Daniel Megersa; [2015]
    Keywords : Onsite waste water treatment; Reactive filter materials; Polonite; Zeolite; Sorption; Ion-exchange; Adsorption; Precipitation; Dual-Column experiment;

    Abstract : Phosphorous and nitrogen are vital elements for the well-being of biological life. Industrial discharges, waste water infiltration systems, conventional waste water collection and treatment systems, agricultural runoffs and landfill leachates had been emitting significant quantity of these nutrients into water bodies.
