HUBER Belt Dryers for Sewage Sludge in Innsbruck, Austria
With a focus on „maximum energy efficiency“ HUBER SE realised a Belt Dryer BT at the Innsbruck Sewage Treatment Plant within a record time of seven months.
The sewage sludge drying in the capitol city of Tyrol allows two-zone drying on different temperature levels. An innovative heat recovery concept of the belt dryer allows more than 400 kWth can be fed to a district heating network.
With its strategy “from sewage works to power plant”, the Innsbruck wastewater treatment plant sustainably produces energy and intelligently integrates it into its existing system. The aim is to further increase the efficiency of the complete sewage treatment works and make it one of the most modern plants in Europe.
