Use of municipal sewage sludge as a source of elektrical energy

Abstract

This work referred to the possibilities of using biogas from municipal sewage sludge in the mesophilic fermentation process at the Sewage Treatment Plant in Wola Further. In 2017, 18,308 m3 of sewage sludge was sent to the WKF, and in 2018 – 23517 m3, resulting in a referral to the cogenerator in 2018 for 21955m3 more biogas than in 2017. The work analyzed the economic efficiency of sewage sludge use in 2017 and 2018, which was 29.3% and 31.7% respectively. The presented solution for the management of municipal settlements allows achieving economic benefits while contributing to a reduction in the environmental impact.
