Column studies aiming at identification of suitable filter materials for pollutant removal from landfill leachate

• Landfill leachate contains a complex mixture of inorganic and organic pollutants, which need to be removed before they pollute the environment. Different filter media (peat mixed with either carbon-containing ash, polyurethane waste, or wood pellets) were investigated with respect to their possibility to simultaneously and at low initial concentrations remove metals, polar and non-polar organic compounds. The mixture of peat and carbon-containing ash was found to be the best medium. Reduction in leachate of phenolic substances was 96%, of PBDEs was over 98%, of DOC 40% and of important metals as Cu, Pb and Sn 60%, 90% and 93%, respectively.
