Performance Evaluation of Sewage Treatment Plants in Lucknow City

Abstract

The present study was conducted to evaluate the performance of existing sewage treatment plants (STPs) in Lucknow City of India. Currently, two STPs are operating in Lucknow, i.e., UASB reactor and FAB reactor, with total operating capacity of 345MLD and 56MLD, respectively. Since, the wastewater get mix with the domestic effluent while directing towards the STPs, therefore, the concentration of BOD is relatively very low, and hence the amount of biogas production by the UASB reactor is also reduced than its design value. Two approaches, evaluating the treatability performance and Life-Cycle Assessment (LCA) have been used to determine the plants efficiencies. All the results have been interpreted graphically. The results of this study conclude that the UASB reactor is better than the FAB, however in terms of LCA the FAB seems to be more reliable.
