The successive anaerobic and aerobic treatment of the UFCW reactors could effectively remove color, organic matters and intermediate aromatic amines simultaneously in a single reactor. With influent 50 mg/L of MO, the removal efficiencies of COD and MO were 91 and 75 %, respectively, in the aerated wetland reactor, whereas the removal efficiencies were 86 and 93 %, respectively, in the non-aerated wetland reactor. The aerated wetland reactor outperformed the non-aerated wetland reactor in the removal of organic matters and aromatic amines. The accumulation of aromatic amines in the non-aerated wetland reactor was observed as shown in the increase of ratio absorbance at 270 nm/465 nm and UV-Vis spectra analysis. 2016-06-25T03:59:38Z 2016-06-25T03:59:38Z 2014 Article Environmental Engineering and Management Journal, vol.13 (1), 2014, pages 37-42 1582-9596 (Print) 1843-3707 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/42195 en Gh.
