Study on Integrated Treatment system for Medium Strength Domestic Wastewater

EasyChair Preprint 2622

Abstract

Domestic wastewater treatment in decentralized manner incorporated with natural systems of treatment is cost effective. 45 kLD integrated and decentralized treatment system was installed in Walchand College of Engineering, Sangli (Maharashtra, India) for the treatment of wastewater generated from residences, hostels and food courts. The system consists of Anaerobic Baffled Reactor (ABR), Baffled and Floating Hybrid Constructed Wetland (BFHCW) and Vertical Flow Constructed Wetland (VFCW). Floating constructed wetland (FCW) which is a part of BFHCW was developed by using the cost-effective floating mat (plastic tray and waste thermocol sheets) vegetated with multispecies wetland plants. Floating rack also has wetland plants vegetated in charcoal bed. Canna Indica and Typha Angustata were used as vegetation in construction wetland due to their abundance and easy availability. The final stage of treatment system consisted of vertical flow constructed wetland filled with mix media of aggregate and coal and vegetated with Canna Indica and Typha Angustata. This integrated system was assessed for its potential to remove COD during July to October, 2018. Anaerobic Baffled Reactor and Floating constructed wetland contributed 35% and 20% for COD removal respectively. Vertical Flow Constructed Wetland contributed 30% for COD removal. The overall COD removal was found to be 70% to 75%
