ABSTRACT

 

The untreated wastewater from households, institutions and industries causes severe deterioration to receiving water bodies. Hence, there is a need of efficient wastewater treatment for the sustainable development. Effort was made to treat the domestic wastewater using customized constructed wetland. Laboratory scale model having inlet and outlet arrangement was fabricated using thick GI sheet of thickness 0.5 mm. It is proposed to provide the treatment of domestic wastewater by using the experimental lab scale model having four reactors. The overall capacity of the model was 60 L. The inlet and outlet arrangement were provided at both ends. The reactor was operated as continuous flow reactor with varying detention time and different types of media. The performance of customized constructed wetland reactor was observed for nearly 5 months under various operating conditions for pH, Biochemical Oxygen Demand (BOD), Total Solids (TS) and Chemical Oxygen Demand (COD) parameters. The Customized Constructed Wetland claims removal efficiencies such as 87% for TS, 83% for BOD and 78% of COD. There was remarkable increase in pH of the effluent. The present paper discusses various aspects associated with Customized Constructed Wetland system. The detailed information about the development and working of the model are also described in detail. The observed data during the study is presented in tabular format
