effect of reed and hydraulic retention time on the lead removal in horizontal subsurface flow constructed wetland
introduction wetlands are classified into four kinds of flows as subsurface, surface, vertical, and hybrid flows. usually, wetlands are planted with common reed (phragmites australis), a rhizomatose plant of the graminae which produces a good yield in green biomass and whose roots can reach a considerable depth and plays a significant role in the wetland self-purification. the treatment efficie...
متن کاملAn experimental study on hydraulic behavior of free-surface radial flow in coarse-grained porous media
The equations of fluids in porous media are very useful in designing the rockfill and diversion dams, gabions, breakwaters and ground water reserves. Researches have been showed that the Forchheimer equation is not sufficient for the analysis of hydraulic behavior of free-surface radial flows; because, in these flows, in addition to the hydraulic gradient and velocity, the variable of radius is...
متن کاملWastewater 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 کاملThe Influence of Short Values of Hydraulic and Sludge Retention Time on Performance of a Membrane Bioreactor Treating Sunflower Oil Refinery Wastewater
In this work, the performance of organic pollutant removal, membrane fouling and sludge morphology in a submerged membrane bioreactor (MBR) treating sunflower oil refinery wastewater (SORW) containing high oleic content was studied during 52 days’ operation at short values of 18 h and 10 days for hydraulic retention time and sludge retention time, respectively. The removal efficiencies of chemi...
متن کاملThe effect of hydraulic retention time on granular sludge biomass in treating textile wastewater.
The physical characteristics, microbial activities and kinetic properties of the granular sludge biomass were investigated under the influence of different hydraulic retention times (HRT) along with the performance of the system in removal of color and COD of synthetic textile wastewater. The study was conducted in a column reactor operated according to a sequential batch reactor with a sequenc...
