DETERMINATION OF QUANTITY OF BIOGAS FROM SEWAGE SLUDGE

key words: sewage sludge, biogas, anaerobic digestion

Summary:

Renewable energy sources have been amongst crucial elements of the European Union policy for a long time. Currently, they have become significant in terms of possibilities of the technology development, which
may limit the effects and duration of the economic, energy and climatic crisis. The Directive 2009/28/EC obliges the increase of the share of Renewable Energy Sources in the final energy consumption up to 20% (in
Poland up to 15%) by 2020. Sewage sludge is waste that significantly affects the aspects of environment. The research considered the rationality of using the waste for the production of biomethane. The purpose of the work was to determine the dynamics of biogas production from sewage sludge of municipal origin. Its scope included a review of the literature based on the Polish and European law. Issues of technology, production and use of biogas and residue were presented. The research was based on determining the properties of sewage sludge - raw and after stabilization, and carrying out a fermentation process for a period of 30 days. The validity of using sewage sludge as substrate for biogas production was confirmed.
