Effect of Feeding with Aeration System on COD removal in Vertical Flow Constructed Wetland

EasyChair Preprint 2057

Abstract

Constructed Wetland (CW) is a part of Decentralized Wastewater Treatment System (DWTS) and used to treat domestic wastewater. Vertical Flow Constructed Wetland (VFCW) and its feeding cum aeration system as part of field-scale Integrated Domestic Wastewater Systems (IDWTS) at Walchand College of Engineering (WCE), Sangli (Maharashtra) planted with Canna indica and Giant reed was assessed in the present study. The performance of VFCW was evaluated for Chemical Oxygen Demand (COD) removal and Dissolved oxygen (DO) enhancement. The study showed that COD removal efficiency of 34% to 43% and DO enhancement upto 1.26 mg/L is possible. Thus feeding cum aeration system developed in the present study significantly improves feed water quality and thereby improving the performance of VFCW for COD removal.
