15. October 2018 Main wastewater treatment plant Stuttgart Mühlhausen The main wastewater treatment plant in Mühlhausen processes the wastewater of more than 1,300,000 population equivalents. This makes the plant one of the largest in Germany. EfU is working on more than 8 projects simultaneously at this site. The operator of this plant, SES, is a technological leader in many areas. EfU provides support in many areas and contributes to maintaining the leading position long-term.
15. October 2018 Wood combustion heat center We as a planning office prefer CO2-neutral technologies. The shown wood combustor of the company Burkhardt is one of them. Here, a synthesis gas is produced from wood in a fully automatic operation 7000 h/a, which is then converted into electricity in an engine. The electricity generated is fed into the grid and the heat produced is used to 100%. The customer is a local heating network. To enable the high running times of the combustor, EfU designed and commissioned a heat storage tank with 3,000,000 liters of water. The predicted operating times were already achieved in the second year of operation.
