Sažetak:
Landfill leachate, collected from the retention basin at the main landfill of the city of Zagreb, was treated using a pilot-scale membrane filtration unit, consisting of ultrafitration and nanofiltration modules. Alternatively, the elimination of organic load was examined using laboratory-scale activated carbon columns. Common water contaminants, such as major cations and anions, chemical oxygen demand (COD) and total organic carbon (TOC), were determined using standard methods, while the identification and quantitative determination of pharmaceutical compounds was performed using gas chromatography – mass spectrometry. Ultrafiltration revealed that 90 % of the organic load of the landfill leachate belonged to the fraction smaller than 10 kDa, while the contribution of pharmaceutical compounds to the total organic carbon was 1-5 %. High removal rates were obtained for the organic load (COD and TOC) both using nanofiltration membranes (85-98 %) and activated carbon adsorption (70-85 %), however, the adsorption capacity of activated carbon was rather small. The removal of pharmaceutical compounds (M.W. from 200 to 300 Da), by nanofiltration was fairly efficient (>90 %). The rejection rates for conductivity and total dissolved solids were much lower (<60 %), which indicated that an additional treatment by reversed osmosis was necessary to eliminate inorganic contaminants more efficiently.
