Abstract

Abstract Sasirangan wastewater has characteristics of high pH as well as high level of biochemical oxygen demand(BOD)and chemical oxygen demand(COD). Sasirangan industries produce large amount of wastewater, which then is directly discarded around the environment without treatment processes. The effect afterward is the oxygen supply in the water diminishes and eventually triggers the activity of anoxic-anaerobic microorganisms that produces odors. Constructed wetlands are able to become the alternative to waste treatment technology at the economical household scale industries. This study was conducted to determine the ability of the removal of BOD and COD in the sasirangan effluent with constructed wetlands (CW) surface flow system using the batch method. Plants used in CW is Hydrilla verticillata, purun tikus (Eleocharis dulcis) and lotus (Nelumbo nucifera). CW was running for 0, 3, 6, 9 and 12 days. This study shows that the best removal of BOD dan COD in CW occurred on 12th days. BOD and COD removal for 12 days at the CW reactor that planted with H. verticillata, E. dulcis, N. nucifera, and the combination of all plant, respectively is 98.19% and 98.41%; 98.74% and 98.73%; 98.48% and 98.61%; 98.89% and 98.83%. It can be concluded that CW planted with H. verticillata, E. dulcis, N. nuciferacan remove BOD and COD on liquid waste sasirangan with the greatest efficiency at CW with combination of plants with retention time of 12 days
