| Summary: | Grey water is one of the most widely type of waste generated from human activities. Increasingly limited land especially in urban areas causing difficulties in the development of wastewater and other waste treatment facilities. Constructed wetland (CW) is one of the alternative technologies that can be applied to process the waste. Vegetation that is used in this system is Akar Wangi (Vetiveria zizanioides). This plant can be grown throughout the year in tropical climates and have characteristics suitable to be applied in wetland technology. In addition Vetiveria zizanioides commonly found in Garut, West Java and has economic value as a raw material essential oil. In this study, four subsurface flow wetlands were constructed for laboratory-scale experiments. The four substrates chosen for experiment were gravel, palm fiber, soil, and limestone. The parameters analyzed include TSS, COD, and nitrogen. The analysis was done by comparing the pollutant removal efficiency in unplanted reactor with planted reactor. |
