Balancing Energy Inputs/Outputs and GHG Emissions for Sustainable Wastewater Treatment – a Case Study
Abstract
The aim of the study is a model-based evaluation of the selected operating modes and technological upgrades on the energy balance and greenhouse gas (GHG) emissions in a large wastewater treatment plant in the city of Slupsk (northern Poland). The considered scenarios focus on energy savings for aeration, increasing energy recovery via biogas cogeneration and reduction of the CO2 equivalent emission from both direct processes (related to biological treatment) and indirect processes (related to energy generation). The simulations of the scenarios revealed a significant potential for both energy balance improvement and reduction of GHG emission. The potential of energy recovery through biogas was found the most influential factor affecting the energy output and GHG emissions of the WWTP. Direct GHG emissions become more significant in the facilities using biogas as a source of renewable energy.
