dc.description.abstractHeavy metal contamination of soil and groundwater have become a harmful issue. Thatswhy effective water treatment utilization were investigated. Low-cost materials, such as industrial waste, secondary waste, by-products, minerals, etc. were found to be efficient and inexpensive adsorbents for heavy metals in aqueous solutions. Twelve sorbents were studied for the heavy metal removal of copper, lead, nickel and zinc in stormwater. The sorbents are bottom ash, fly ash, montmorillonite, kaolinite, zeolite molecular sieve, olivine, bark, sea weed, saw dust, aluminum oxide, iron (III) oxide and granulate activated carbon (GAC). The sorbents were studied to find effiecient soil filter media, therefor sorbents with a smaller particle size were mixed with sand to prevent clogging . Batch test showed that the removal efficiency of all sorbents for four different multi metal concentrations. While the metal uptake of the sorbent/ sand mixtures were mostly not satifying other sorbents was able to remove up to 100 % of each havey metal. The effect of cold climate was analyzed by adding salt into the synthetic stormwater. The leaching ability and the heavy metal removal in a synthetic stormwater with added salt was tested for bark, olivine, granulate activated carbon and zeolite molecular sieve. With increasing salt conentration the removal effectivness of bark decreased, while the other three sorbents was unaffected. Also the adsorbed metals on bark leached in synthetic stormwater with added salt.en_US
