Abstract

Constructed wetland is engineered, man-made ecosystems is one of the wastewater treatment systems to reduce water pollution by using plants. The purpose of this study to know the efficiency of Sub-Surface Flow constructed wetland with Vetiveria zizanioides in domestic wastewater treatment and to reveal the effect of aeration and detention time to reducing BOD concentrations in domestic wastewater. The research has been conducted in constructed wetland located in Srengseng Sawah Village of continue aerated reactor and without aeration as control reactor. Detention time (days) 2 and 3 was setup, then sample was taken for BOD concentration. The results indicated that constructed wetland with aeration and detention time 4 days had a higher performance to remove BOD up to 90% than without aeration and less than 4 days process. This results fulfill the requirement of the quality standards of the Decree of DKI Jakarta Governor No. 122 of 2005 and Decree of the Minister of Environment No. 112 of 2003
