Possibilities of Sludge Recovery From Wastewater Treatment Plant

Abstract

The aim of this study is to focus on environmental benefits, or eventual loads of sludge life cycle in the wastewater treatment process. Life Cycle Assessment was used to evaluate the environmental impacts associated with the treatment of wastewater in a wastewater treatment plant (WWTP) in Vráble, based on the general standard EN ISO 14040. From the measured experimental data, the environmental impacts of the sludge management are quantified using the LCA method. For impact assessment is using the OpenLCA program, together with the available databases and assessment methods. The LCA results of Vráble WWTP taking renewable energy as the energy source proposed that enhancing the effluent quality will decrease the environmental impacts.
