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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
