Nutrient 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 کاملEffect of Electrical Conductivity (ec) on Growth Performance of Duckweed at Dumpsite Leachate
Two batch experiments were conducted during the months of June-July (summer) and September-October (fall) to determine the effect of Electrical Conductivity (EC) on nutrient and COD removal & uptake efficiency and growth of duckweed (Lemna minor) at leachate with various EC levels (500-3,000 μS cm -1 ) under the natural climatic conditions of Islamabad, Pakistan. Maximum removal rates (mg m -2 ...
متن کاملNutrient Removal from Leachate
Remediation of the City of Zagreb Jakusevec Dump Site, one of the largest dump sites in Europe, is in progress. Experimental laboratory results of leach ate treatment using aquatic macrophytes show that increasing the concentra tion of ammonia in the leachate decreases elimination efficiency. In all series of experiments, significantly greater elimination of ammonia and orthophos phates has ...
متن کاملPotential of Duckweed (Lemna minor) for Removal of Lead from Wastewater by Phytoremediation
This investigation was undertaken to study Pb uptake by small free floating aquatic plant Lemna minor from wastewater polluted by contaminated with heavy metals. Metal accumulation process was affected by various parameters such as different pH, temperature and concentration of Pb solution. Total chlorophyll contents in Lemna minor was adversely affected from increased with increasing Pb concen...
