The emergent plant selected in our study was Phragmites australis. Toxic signs were observed at the Phragmites australis after the addition of AO7 into the wetland reactors but it can adapt to the wastewater as shown in the increase of stem as the operation continue. Our result shows that the artificial aeration and the presence of Phragmites australis had a significant impact on the removal of organic matters, AO7, aromatic amines and NH4-N. The COD removal efficiency in the aerated and non-aerated wetland reactors was 95 and 62%, respectively. The NH4-N removal efficiency in the aerated wetland reactor (86%) was significantly higher than the non-aerated wetland reactor (14%). All wetland reactors show high removal efficiency of AO7 (> 94%) but only the aerated wetland reactor perform better in the removal of aromatic amines. 2016-06-25T04:23:40Z 2016-06-25T04:23:40Z 2011-10 Article Journal of Engineering Science and Technology (JESTEC), vol.6 (5), 2011, pages 623-631 1823-4690 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/42198 en Taylor's University College
