Usage of Waste Water Treatment Plants Hydroelectric Energy for Urban Lighting Energy: The Case of Turkey

Abstract

In this study, primarily from wastewater treatment plants in seven geographical regions in Turkey value of electrical power that can be generated were calculated. Then, a study was carried out to determine the ratio of the electrical power generated to meet the lighting energy requirement in the relevant geographical region. For this purpose, a method for evaluating the hydroelectric potential of wastewater treatment plant was presented. For seven geographical regions, population prediction in 2018-2025, predicted flow rate of wastewater to be treated from wastewater treatment plant and lighting consumption for each region were predicted. Predictions for the future years were made by using the equations obtained through the curve fitting algorithm written in Matlab environment. Using these values, the predicted electrical power values were calculated in case the distance between the treated wastewater falls and the turbine where electricity generation took place was 3 meters. According to study total predicted wastewater would be 4.16 (2018) and 5.89 (2025) billion m3. Total cities’ predicted lighting energy consumption in Turkey would be 4429.2 GWh (2018) and 4941.5 GWh (2025). And yearly predicted electricity generation from wastewater treatment plant hydroelectric would be 28.51 GWh (2018) and 38.53 GWh (2025).
