 The main aim of the project is to design a UASB reactor instead of an Aeration tank. The discharge flow for the Activated Sludge Process is 8.70 MLD. The UASB reactor had recovered the energy from sewage. The UASB process reduces the volume of the tank and also reduces the size of the plant. The total power requirement of the plant will be 2800 kWh per day during the design flow of 8.70 MLD. Due to usage of UASB reactor, the total power requirement leads to reduce by the Gas turbine. In Indian municipalities, this UASB reactor adopted only a few numbers due to the limitation of the process. This research work suggests the process for the upcoming proposed sewage treatment plant.
