Water supply system of Poznan & Central Wastewater Treatment Plant

Renewable Energy Sources

Use of renewable energy from biogas at facilities operated by Aquanet: Central Wastewater Treatment Plant in Koziegłowy and Left-Bank Wastewater Treatment Plant in Poznań. Biogas – biofuel (Aquanet for Carbo. Europe 8. 10. 2007)

Biogas - biofuel Sludge generated as a result of wastewater treatment processes is transported to six separate digesters and subjected to anaerobic digestion. The anaerobic digestion processyields biogas. The net calorific value of biogas amounts to 21. 6 MJ/m 3 In August 2007 - ca. 960. 000 k. W. Annual - 12. 365 MW (electricity) - 16. 307 MW (heat) Biogas – biofuel (Aquanet for Carbo. Europe 8. 10. 2007)

Environmental and economic effect. Biogas – biofuel (Aquanet for Carbo. Europe 8. 10. 2007)

The environmental effect - generation of electricity from biogas considered to be biofuel (utilisation of 100 % biogas generated during the digestion process) - elimination of emissions of CH 4 (methane ) and CO 2 (protection of the atmosphere and reduction of the „greenhouse effect”) Biogas – biofuel (Aquanet for Carbo. Europe 8. 10. 2007)

The economic effect - covering 40% of the demand for electricity (reduced purchase of electricity from the municipal power supplier) - possibility of selling ‘green power’ in the market - obtaining additional reject heat which is used for process purposes and for the heating of the treatment plant buildings and facilities.
