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 کاملMonitoring and modelling of free water surface constructed wetlands
Integrated water management has encouraged the construction of small scale wastewater treatment plants to treat residual discharges. For this study, six free-water-surface constructed wetlands have been monitored from September 1998 till April 1999 to determine their operational efficiency. These natural systems have been constructed by the Flemish Land Authority (VLM) in Wontergem. Design load...
متن کاملConstructed Wetlands for Water Treatment: New Developments
Constructed wetlands (CWs) are currently regarded as established eco-technologies to treat water pollution. Although considered near-natural systems, they are totally engineered solutions for which research has been actively developed over the past decades. This paper provides a brief meta-analysis on the latest scientific publications in the field and an overview of the special issue focused o...
متن کاملPotential of constructed wetlands in treating the eutrophic water: evidence from Taihu Lake of China.
Three parallel units of pilot-scale constructed wetlands (CWs), i.e., vertical subsurface flow (VSF), horizontal subsurface flow (HSF) and free water surface flow (FWS) wetland were experimented to assess their capabilities in purifying eutrophic water of Taihu Lake, China. Lake water was continuously pumped into the CWs at a hydraulic loading rate of 0.64 m d(-1) for each treatment. One year's...
متن کاملUse of Constructed Wetlands in Water Pollution Control: Historical Development, Present Status, and Future Perspectives
During the last two decades the multiple functions and values of wetlands have been recognized not only by the scientists and managers working with wetlands, but also by the public. The ability of wetlands to transform and store organic matter has been exploited in constructed wetlands. This paper summarizes the state-of-the-art of the uses of constructed wetlands in water pollution control by ...
