Abstract

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 COD, pH and Electrical Conductivity (EC) were investigated in the planted batch system. Experimental studies were maintained in 4 reactors at room temperature. The maximum COD removal efficiency was determined as 62.2% and 60.1% in the reactors with 5 cm and 10 cm depth, respectively. The pH with an initial value of 7.91 was between 7.91-8.49 at various hydraulic retention times. The electrical conductivity with an initial value of 5.59 mS/cm was reached to a maximum of 9.46 mS/cm.
