Worldwide Success of Tyrolean Wastewater Treatment Technology

27.05.2016

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.

The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70 wastewater treatments plants around the world. A new partnership has now been formed between the environmental engineers in Innsbruck and the US-utility company DC Water for jointly refining and marketing the technology.

In Blue Plains in Washington, DC, USA, the new partner is currently building the world’s largest deammonification system in a wastewater treatment plant. Similar systems are currently being planned and built in Stockholm, Singapore, Yokohama and Jerusalem.

In northern Europe, the DEMON®-system has been implemented by long-time license holder Sweco, formerly Grontmij, and this partnership is going to be extended with a new contract. Co-developer Bernhard Wett explains the reason why so many major cities have expressed interest in this technology:

“The DEMON®-system is particularly interesting for wastewater treatment plants that have reached their capacity-limit because with this technology the treatment of ammonium-rich wastewater can be intensified significantly.”

Energy-efficient, environmentally friendly and globally successful

The DEMON®-technology utilizes a biological process for removing large quantities of ammonium from wastewater. “However, it is technically difficult to implement the process because the bacteria grow extremely slowly and are very sensitive,” says Bernhard Wett.

“We successfully implemented the first system in a wastewater treatment plant in Strass, in the Zillertal valley in Austria. This treatment plant is the first energy self-sufficient wastewater treatment plant globally. Therefore, it can be considered as a prototype of our system, which has attracted interest around the world.”

This innovative technology uses 60 percent less energy than conventional systems and, moreover, it doesn’t require any chemicals. “The development and marketing of the patent has been a huge success story for the University of Innsbruck,” underlines Tilmann Märk, Rector of the University of Innsbruck.

“With this newly established US-cooperation, it is possible to further refine the technology, which will guarantee its success in the future.”

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...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
