The pilot study of COD Removal in Industrial complex effluent by wetland plants Cyperus rotundus Linn

Present study was carried out to determine the high COD of GIDC (Gujarat Industrial Development Corporation) areas. One of the burning problems of Industrial society is the high consumption of water and the high demand for clean drinking water. Numerous approaches have been taken to reduce water consumption, but in the long run it seems only possible to recycle wastewater into high quality water. In this study, an attempt was made to compare the efficiency of grass lend plants like Cyperus rotundus Linn. To treat the effluents from GIDC Common treatment plant (NEPL-Naroda Enviro Projects Ltd.) in constructed wetlands DF system beds. The chemical oxygen demand of Complex effluent was reduced significantly after treatment. The Cyperus Rotundus. based treatment system was the most efficient in removing the pollutants from the effluent. So in conclusion, Cyperus species were more efficient than the constructed wetland technology.
