2.5 CONCLUSIONS
This study focuses on the energy aspect of WWTPs. The use of the existing biogas
and hydropower energy potential in WWTPs has been analyzed. The new energy
laws and the market conditions in most countries around the world create an oppor-
tunity to harness this potential. As a case study, Tatlar WWTP in Ankara has been
investigated in a detailed manner. The annual electricity consumption of Tatlar
WWTP was 26.5 GWh in 2013. The installation of an Archimedean screw at the
outlet of the WWTP has a payback period of less than 3 years, and hydroelectricity
generation exceeds the electricity consumption by about 30%, producing clean and
feasible energy. The findings of the case study demonstrated that by using biogas
and hydro energy together, the energy recovery efficiency of a WWTP can exceed
100%, which is consistent with the operational data of Samra WWTP in Jordan.
These energy-related technological solutions can make considerable contributions to
sustainable WWTP development.
