  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. 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. Reningseffekten av fosfor och kväve i regnbäddar

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Elnaz Habibi; [2021]
    Keywords : regnbädd; biofilter; näringsämnen;

    Abstract : Flera hårdgjorda ytor och mindre vegetation i våra städer har orsakat att den naturliga infiltrationen minskar. Hårdgjorda ytorna gör att det blir en snabb avrinning som den traditionella dagvattensystem inte kan klara av. Detta ökar risken för översvämningar samt ger negativa effekter till miljön. READ MORE

  6. 5. Are organohalogen compounds in backwash water from swimming pool facilities treatable? : An experimental investigation of removal capacities by different filter materials

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emma-Helena Ericsson; [2020]
    Keywords : AOX; EOX; wastewater treatment plant; column test; granular activated carbon; natural zeolites; Polonite r ; Zugol;

    Abstract : Organohalogen compounds are formed in swimming pool waters when natural organic matter, such as hair, urine or sweat etc., react with the used disinfectant (usually chlorine). Many of the organohalogen compounds are persistent and hazardous for human health and aquatic ecosystems. READ MORE
