Biological Treatment of Domestic Wastewater Using Sequential Batch Reactor (SBR)

Abstract

A lab-scale aerobic Sequencing Batch Reactor (SBR) was investigated to treat the domestic wastewater. The reactor was constructed from Plexi glass material and its volume was 22 litres. The reactor was supplied with oxygen by fine bubble air diffuser. The reactor was fed with the domestic wastewater collected from the sewer line for the H9stel of Coimbatore Institute of Technology. The study was conducted to determine the treatability of domestic wastewater by SBR and to evaluate (standardise) the reactor parameters such as total cycle time, temperature and aeration rate for carbonaceous constituents removal efficiency.
