Wastewater Treatment with Vertical Flow Constructed Wetland
Water is one of the most important elements involved in the creation and development of healthy life. Haphazard disposal of untreated wastewater from households as well as institutions and industry is causing severe deterioration of water bodies in many urban areas in the developing world. There are several methods to treat the municipal wastewater for intended use. One of the methods of the tr...
متن کاملWhich Hydraulic Model to Use in Vertical Flow Constructed Wetlands?
Modeling water flow in a VFCW is a prerequisite to model wastewater treatment using process based filtering models. As for soils, when the vertical structure varies in different material types, it has a significant impact on water flow passing through it. The heterogeneous filtering material is composed of a mix of mineral porous material, and organic matter which makes its hydraulic characteri...
متن کاملEffect of aging on phosphorus speciation in surface deposit of a vertical flow constructed wetland.
This study was conducted to determine phosphorus (P) species captured in a vertical-flow constructed wetland (VFCW) system combining a trickling filter followed by FeCl3 injection for phosphate coagulation. Suspended solids (SS) thus formed accumulated over time at the VFCW surface and transformed into a sludge deposit layer, which was shown to concentrate most of the P captured in the system. ...
متن کاملRecirculation on a single stage of vertical flow constructed wetland : treatment limits and operation modes
Classical French vertical flow constructed wetlands (VFCWs) plant comprises two stages of treatment which the first one nearly respects standard outlet levels. It is therefore attractive to use recirculation on a single vertical stage to reduce its footprint when outlet levels required are not too severe regards to nitrification. The present study aims at evaluating performances and limits of a...
متن کاملSimulation of a subsurface vertical flow constructed wetland for CSO treatment.
Constructed wetlands (CWs) have proved to be a highly effective measure to reduce the ecological impact of combined sewer overflows (CSOs) on receiving waters. Due to the stochastic nature of the loading regime and the multitude of environmental influences, assessment of the performance of such plants requires detailed mathematical modelling. A multi-component reactive transport module (CW2D) w...
