ABSTRACT
In this chapter, the author addresses use of biogas and hydro energy by using the real-time operational data of a waste water treatment plants (WWTPs) in Turkey. Sludge production is increasing year by year parallel to the increasing number of WWTPs, and moreover, the use of sludge in agriculture is completely forbidden in some countries, such as the Netherlands, South Korea, and Switzerland. Samra wastewater treatment plant in Jordan is an example of electricity production from wastewaters before and after the WWTP. Tatlar WWTP, which is the one of the biggest WWTPs in Europe, has been operated by the Municipality of Ankara since 1993. Public awareness of environmental issues, especially greenhouse gas (GHG) emissions, decarbonization of energy sources, and energy, efficiency directed WWTPs toward producing their own energy and hence, net neutral energy consumption. Assessing reliable and sufficient discharge data during the planning phase of a hydropower development is necessary to accurately estimate the hydro energy yield.
