  1. 1. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : William Gulding; [2023]
    Keywords : Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Abstract : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. 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. Phosphorus Removal and Methylene Blue Adsorption by Porous Calcium Silicate Hydrate.

    University essay from KTH/Mark- och vattenteknik

    Author : Asanka Welagedara; [2013]
    Keywords : Absol; Batch experiment; Sorption capacity; Adsorption kinetic; ;

    Abstract : Nutrients (nitrogen and phosphorus) should be removed and recycled from wastewater in order to reduce the nutrient load to recipient waters, avoiding contamination of groundwater and conserve resources. There is a need to pay more attention to phosphorus (P) removal and recycling from wastewater due to limited availability of phosphorus recourses. READ MORE

  6. 5. Phosphorus Removal from Domestic Wastewater Using Dual Reactive Materials Polonite® and Absol®.

    University essay from KTH/Miljögeokemi och ekoteknik

    Author : Soheil Fatehi Pouladi; [2011]
    Keywords : Polonite; Absol; Domestic wastewater; Phosphorus removal; Reactive filter material; Soil infiltration bed;

    Abstract : Private wastewater treatment facilities release tons of phosphorus to the aquatic environment due to the insufficient removal efficiency in conventional soil infiltration systems. Reactive filter materials have demonstrated promising P removal rates. READ MORE
