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 کاملPhysical-chemical characterization of sludge and granular materials from a vertical flow constructed wetland for municipal wastewater treatment.
The use of vertical flow constructed wetlands (VFCWs) is well developed in France and other countries for the treatment of wastewaters from small communities. The patented Azoé® process has been developed by a French company, SCIRPE, in order to improve denitrification and phosphorus removal as compared to classical VFCWs. It includes a biological trickling filter pretreatment followed by two s...
متن کاملA promising approach of reject water treatment using a tidal flow constructed wetland system employing alum sludge as main substrate.
This study examined a novel reuse of alum sludge, an inescapable by-product of drinking water treatment process when aluminium salt is added as a coagulant, as the main medium in a laboratory-scale multi-stage constructed wetland (CW) system for reject water treatment. Such reject water is a main concern in municipal wastewater treatment plant (MWWTP) for increasing the organic and nutrient loa...
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...
