Nutrient removal was studied in a pilot plant of reeds (Phragmites sp.) planted on soil and on gravelbed, and fed with the biologically treated domestic sewage of the city of Sparta, Greece. Substantial removal of the incoming nitrogen load was achieved through combined nitrification - denitrification processes, but only small removal of phosphorus was observed. The reed system on gravel reached better nitrification rates, while denitrification was higher in the reed system grown on soil bed. However, the nutrient removal capability of both systems was seriously reduced when the influent ammonia load was increased. The reed bed system exhibited seasonal variations in their nutrient removal capacity, with the highest removal rates observed during summer and early autumn.
