Abstract
Common reed (Phragmites australis), or simply called reed, is a tall and robust grass species which can be found in many tropical countries, primarily in freshwater and light brackish wetlands.Reed is widely used to treat various forms of wastewater in the constructed wetlands. Phragmites australis stores larger amounts of the nutrient within their biomass. It is assumed that the values of transpiration are increased as a result from the growth of common reed biomass. Based on the water balance equation in a closed system as a constructed subsurface flow wetland, the transpiration of water inside the soil to the air via its plant system were determined. The result shows that reed consume a lot of wastewater by transpiration.Increasing transpiration of the reed in a constructed wetland (mm/12hr) is a function of the experimental dates.
