Abstract The present study was undertaken to investigate the potential of Canna-based constructed wetlands in nutrient removal from wastewater. A Vertical Flow Constructed Wetland (VF CW) was used in this study and removal of Phosphorus (Available Phosphate and Total Phosphorus) and Nitrogen (Ammonia) by a vegetation layer of plant Canna lily was assessed. The findings showed that removal of ammonia varied with temperature from 72 to 52% as nitrification is reduced with temperature. Removal of total phosphorous varied between 66 to 40% in Canna-based vertical flow constructed wetland was found to be lower than removal of available phosphate 79 to 56%. Available phosphate is directly available for plant uptake and has fewer fluctuations in its removal. In the initial phase of growth of the plant removal was found high due to high uptake of plant and soil exchange capacity. The study concludes that biological oxidation play important role in the transformation of nutrients into the system, efficiency of which depends upon various physical and chemical parameters.
