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 کاملNutrient removal efficiency by floating macrophytes; Lemna minor and Azolla pinnata in a constructed wetland
The use of constructed wetlands for purifying pre-treated wastewater is a cost effective technology that has been found to be more appropriate for many developing countries. The technology is also environmentally friendly with the wetlands being habitats for many water birds and other aquatic organisms. This study assessed nutrient removal efficiency of two floating macrophytes (Lemna minor...
متن کاملRemoval of Pharmaceutical Products in a Constructed Wetland
Background: There is growing interest in the natural and constructed wetlands for wastewater treatment. While nutrient removal in wetlands has been extensively investigated, information regarding the degradation of the pharmaceuticals and personal care products (PPCPs) has only recently been emerging. PPCPs are widely distributed in urban wastewaters and can be removed to some extent by the con...
متن کاملNitrogen removal in constructed wetland systems
Since the mid 1990s, constructed wetlands have been increasingly used as a lowenergy ‘green’ technique, in the treatment of wastewater and stormwater, driven by the rising cost of fossil fuels and increasing concern about climate change. Among various applications of these wetlands, a significant area is the removal of nitrogenous pollutants to protect the water environment and to enable effect...
متن کاملElectroflocculation – Constructed Wetland Hybrid for Improved Phosphate Removal In Effluent Reuse
Reusing or recycling wastewater for stream rehabilitation require discharge of high quality effluent complying with strict nutrient standards as well as development of feasible treatment alternatives. Constructed wetland is already a proven technology for efficient polishing wastewater effluent except for phosphorous. We investigated the coupling of Electroflocculation (EF) with constructed wet...
