PENGOLAHAN AIR LIMBAH HOTEL DENGAN METODE FREE SURFACE CONSTRUCTED WETLAND MENGGUNAKAN TUMBUHAN EQUISETUM HYMALE

Abstract

Throwing domestic waste water directly to the drainage without treatment had caused the water pollution. The effect of water pollution can disturb the health and water biota. One of simple technology to decrease the pollutant in the water is constructed wetland. This research is aimed to know the effectivity of Free Surface Constructed Wetland with water bamboo (Equisetum Hymale) and peat in processing the hotel waste water. The research used constructed wetland. The quality parameter of water that was tested are pH, COD, TSS. Statistic calculation that was used in this research is one way Anova (Analysis of variance) .The result of the research showed that the constructed wetland with peat and water bamboo (Equisetum Hymale) resulted the highest effeciency in decreasing pH from 8.5 to 6 or 29.41% , COD from 97.7 mg/l to 43 mg/l or 55.98% , and TSS from 447.90 mg/l to 66.00 mg/l or 85.26%. Constructed wetland with the media of peat and without using the plant resulted the highest effeciency in decreasing pH from 8.5 to 6.5 or 23.53% , COD from 250 mg/l to 173 mg/l or 30.8% , and TSS from 447.90 to 79.20 mg/l or 82.32% All result showed that constructed wetland can improve the quality of the waste water.
