Abstract—Performance of vegetated horizontal subsurface-flow constructed wetland was evaluated for the removal of ammoniacal nitrogen (AN), total reactive phosphorus (TRP), and soluble reactive phosphorus (SRP) from landfill leachate. Four reactors were used, namely RI (granite without vegetation), RII, and RIII which consists of granite and gravel with different sizes respectively and RIV contained sand and 67.5 L of charcoal. RII, RIII, and RIV were planted with cattails. The leachate obtained from the site of Pulau Burung Sanitary Landfill, Penang was introduced into RI at flow rate of 18 mL/min which was continuous to flow through another three reactors. The leachate was analyzed for AN, TRP, and SRP before and after the treatment in each reactor by standard methods. The overall average removal efficiency of AN, TRP, and SRP were 86.7, 86.2, and 90.0%, respectively. Reactor IV performed the best for removal of all the parameter studies.
