A rectangular HSSFCW with 6 m long, 3 m wide ,1 m deep and divided into 3 compartments was used. Gravel beds were used as medium. <em>Canna sp</em>, <em>Heliconia sp</em>., and <em>Papirus sp</em>. were planted with plant density 10 plants per m<sup>2</sup>. The result showed that removal of ammonia was 67-87%, nitrite was 26-96%, nitrate was 35-99%. Ammonia removal relies on the efficient nitrification that requires sufficient amount of oxygenand organic carbon source to obtain optimum removal.</p> ER -
