Investigating the efficiency of surface flow constructed wetlands by using Cyperus alternifolius plants for nitrate removal from water
Background and Objective: Synthetic wetlands are engineering systems that use natural plants, soils and organisms to purify municipal polluted water and remove nitrate. Materials and Methods: In this study, three systems were considerd as soil culture, three systems as plant cultivation on floating plates and three other systems without plant and porous bed as. The experiments were done three ...
متن کاملRecirculating Vertical Flow Constructed Wetlands
In parts of the United States where soils are very permeable, conventional septic tank and absorption field systems are considered the largest contributor to waterborne disease and pollution of water bodies. However, an economical, recirculating vertical flow (RVF) constructed wetland, used as a pretreatment system, can significantly improve the performance of conventional onsite wastewater tre...
متن کاملSurface Flow Constructed Wetlands as a Drainage Management Tool – Long Term Performance
Subsurface tile drains are used extensively throughout many agricultural areas of New Zealand to reduce excessive wetness from grazed pastures. Along with transporting water, subsurface drains also transport nutrients which have leached from the soil, potentially bypassing natural attenuation processes in shallow groundwaters and riparian zones. These nutrients have the capacity to cause excess...
متن کاملMitigation of chlorpyrifos runoff using constructed wetlands.
Constructed wetlands have been proposed as a potential best management practice (BMP) to mitigate effects of pesticide-associated agricultural runoff. Wetland mesocosms (14 m x 59-73 m) were amended with chlorpyrifos to simulate a storm runoff event at concentrations of 73, 147 and 733 microg/l. Water, sediment and plant samples collected weekly for 12 weeks indicated that chlorpyrifos rapidly ...
