In this sudy, the mixture of duckweeds of Lemna gibba L., Lemna minor L., Spirodela polyrrhiza and Wolffia arrhiza was used for treatment of leachate and changes of nutrients were investigated in the planted batch system. In the study, NH+ -N, NO-N, NO-N and O-POconcentrations were determined. Experimental studies were maintained at 2 various depths (5 and 10 cm) and various hydraulic retention time. The maximum NH+ -N removal efficiency (75.3%) was determined in the reactor with 5 cm depth at day 9. It was observed that there was not any removal in concentrations of NO-N ve NO-N. The maximum O-POremoval efficiency (44.6%) was determined in the reactor with 5 cm depth.
