SynGas sewage sludge gasification plant in Mannheim
The sewage sludge gasification plant at the wastewater treatment plant of the municipal wastewater works Mannheim was built in 2010 and commissioned in 2011. The process is largely based on the pilot plant in Balingen, which has been in operation since 2001.
However, the plant’s capacity of 5,000 t/a DS is more than twice that of Balingen. This is about half of the annual sludge produced by the wastewater treatment plant, which is designed for 725,000 PE and treats approx. 35,000,000 m³ of wastewater per year.
After a purification stage, the synthesis gas produced from the gasification process is fed to the furnace of the drum dryer installed at the sewage treatment plant in the neighbouring building for sludge drying.
