2007 (English)In: Highway And Urban Environment / [ed] Morrison, GM; Rauch, S, 2007, Vol. 12, 309-317 p.Conference paper (Refereed)
Removal of dissolved heavy metals in road runoff can be achieved by filtration through reactive materials. A four-column installation was set up at an existing treatment plant and used to examine different types of filter materials in situ. Two fractions of granulated activated carbon (GAC), Clinoptilolite and Polonite were investigated. The hydraulic loading was 1 m h(-1) and the metal attenuation capacities were studied under unsaturated and saturated conditions. The relative effectiveness of the materials decreased in the order: GAC of fine fraction > GAC of course fraction > zeolite > Polonite. Aluminium, Fe, Mn, and Zn showed the highest concentrations in influent storm water and also showed elevated removal efficiencies.
