A short-term column experiment with sorbents was performed to test their removal efficiency of phosphate-phosphorus (PO4-P) and ammoniacal-nitrogen (NH4-N) from landfill leachate. Twenty litres of leachate was taken from a landfill near Stockholm and contained in average 233 g/L of PO4-P and 139 mg/L of NH4-N. The sorbents used were opoka, calcinated opoka, zeolite, peat and sand. Four columns were used and filled to a volume of 0.15 L with opoka of 0-1 mm grain size (I), sand 2 mm (II), calcinated opoka (0-2 mm) mixed with zeolite (2 mm) in the proportion I: I (III), and peat mixed with calcinated opoka (IV). More than 90% of P was removed in column III and IV. Columns I and II removed only 42 and 39%, respectively. The sorbents were not promising for removal of ammoniacal nitrogen. The highest removal efficiency was found for column III, a removal of 30%.
