Siemens helps transform the main wastewater treatment plant in Vienna into a green power plant

30.11.2015
  • Use of sewage gas for power generation
  • Siemens supplies the control, measuring, analytical and electrical energy systems
  • New procedure for energy-efficient treatment of sludge
  • Contribution toward climate and environmental protection as well as sustainable power generation

Siemens will support the city of Vienna in optimizing its main sewage plant in terms of energy. For this purpose, Siemens is supplying the control, measuring, analytical and power distribution systems, as well as the low-voltage and medium-voltage switchgear.

Furthermore, the order includes the installation and commissioning of the individual systems. The order is worth around 24 million euros and is part of "E_OS 2020" (Energy_Optimization Sludge Treatment), the largest environmental project ever undertaken by the city of Vienna.

As from 2020, the main sewage plant will use sewage gas to generate autonomously all the energy required for the wastewater treatment. For the sewage treatment itself, a particularly efficient method is used with reduced water content and double the solid content. This considerably reduces the energy consumed during anaerobic digestion and gas generation.

The main sewage plant, which currently is among the largest energy consumers in the community, should generate an output of 78 GWh of electricity and 82 GWh of thermal energy. In total this method should save about 40,000 metric tons of CO2 per year.

Christian Gantner, Director General of the ebswien main sewage plant: "Our conversion of the wastewater treatment plant into a green power plant makes a valuable contribution to both a responsible use of natural resources and to sustainable power generation. The efficient technologies of our partner Siemens play a key role in achieving our ambitious environmental and climate targets."

Wolfgang Hesoun, Chief Executive Officer of Siemens AG Austria: "An essential factor of success for achieving the environmental targets of a city are the measures that generate maximum ecological and economic benefit. On the basis of extensive analyses we have managed, together with our customer, to develop a tailor-made solution that will help the largest environmental project ever undertaken by the city of Vienna to become a success. In doing so, we are focusing as much on energy efficiency, preservation of resources and sustainability as we are on smart technologies and networked systems."

The order includes the migration and expansion of the existing Simatic PCS 7 process control system to the latest Version 8.1. The conversion work is taking place in parallel with normal operations. All functions are tested already in the engineering phase with the Simit simulation software, enabling quality to be assured and commissioning times to be shortened. In addition, Siemens is supplying Sitrans process instrumentation, devices for gas analysis (Ultramat/Oximat), as well as Scalance network components, including cabling, installation and commissioning. For a safe, high-availability power supply to about 450 motors and drives in the sewage plant, Siemens is installing a redundant 20 kV medium-voltage power distribution system of the type NXAir (28 fields), Sivacon S8 low-voltage power distribution systems (about 80 fields), a busbar trunking system, and 14 transformers. The protection devices of the existing systems and those of the new systems are equipped by Siemens with Ethernet-based communication interfaces. The redundant SICAM AK 3 station control technology processes all data points from the energy supply and delivers these to the higher-level switchgear control technology and subsequently for the overall monitoring of the new process control system.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
