Transport of Kolloids by the Infiltration of Stormwater - Characterization of Interactions Colloids/Contaminant (KORESI)
Transport of Kolloids by the Infiltration of Stormwater - Characterization of Interactions Colloids/Contaminant
The sustainable urban drainage integrates the infiltation of stormwater from roof and street surfaces. The street and roof runoffs may contain pollutants e.g. Zn, Cu, Pb, Pt, As and polycyclic aromatic hydrocarbons (PAH). The aim of the project is (a) the quantification of the colloidal transport of those pollutants in subsurface and (b) the investigation of the interactions colloids/contaminants. Column studies are performed with quartz sand as model aquifer and model solutions and street and roof runoffs. The pH, ionic strength and hydraulic parameters are variied. Watersaturated and unsaturated conditions are simulated. The characterization of the influent and effluent and the investigation of the interactions colloids-NOM-metals/PAK are performed with zetasizer, FFF, FFFF, HPLC, ICP/MS and the coupling of ICP/MS with chromatographic methods and other techniques.
