Abstract

Kurichi is a region located in Coimbatore city of Tamil Nadu which was upgraded to a municipality in the year 2004. Recently it was merged with the Corporation of Coimbatore. As per census 2011, the town had a population of 123,770 people. The domestic waste water generated from this area is allowed to mix in the lake situated near the location, without undergoing any primary treatment process. Aim of the present study is to investigate the feasibility of using a, Eichhornia crassipes in constructed wetland for treatment of wastewater at Kurichikulam. Wetlands are land areas which are wet during part or all of the year is referred as wetlands. Constructed wetlands are manmade systems that mimic the functions of natural wetlands and they are applied for wastewater treatment system. The physico-chemical parameters of the inlet and outlet wastewater were analysed during the period of two months. The parameters studied were pH, BOD, COD, DO, Total Suspended Solids, Total Dissolved Solids, Nitrogen and Phosphorus. The study revealed that the surface flow constructed wetlands are best alternative solution to prevent the lake getting polluted with domestic waste water among other modern treatments.
