Customized Constructed Wetland - An Experimental Study over Specially Modified Constructed Wetland

Severe damage to water bodies is caused due to the untreated wastewater from industries, institutions and households. Hence, there is a need of effective wastewater treatment technologies for the sustainable development. To treat the medium strength domestic wastewater, an Experimental laboratory scale model of constructed wetland was developed. Experimental Lab scale model having inlet and outlet arrangement was fabricated using thick GI sheet of thickness 0.55 mm. It was proposed to provide the treatment of medium strength domestic wastewater by using the experimental lab scale model having four numbers of compartments. The overall capacity of the experimental lab scale model was 60 L. The Inlet and outlet arrangement were provided at both ends of the model. The reactor was operated as continuous flow reactor with varying detention time and different types of media such as Natural and Artificial. The performance of customized constructed wetland reactor was observed for nearly 5 months under various operating conditions for Biochemical Oxygen Demand, Total Solids and Chemical Oxygen Demand parameters. The Experimental Lab scale Model of Customized Constructed Wetland claims removal efficiencies such as 74.11% for Total Solids, 73.92% for Biochemical Oxygen Demand, and 72.17% of Chemical Oxygen Demand. 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.
