Viewing waste water as valuable resources - Science for schools

13.02.2006


Two schools in Leipzig are taking part in a new EU project called “Play with Water – From Waste to Resource”. Scientists from the Centre for Environmental Research Leipzig-Halle (UFZ) are involved, along with partners from a wide range of research establishments in Switzerland, Denmark, Norway, Sweden and Slovenia. The concept was developed as part of the EU’s Science and Society Action Plan.



The target group for this project from the Training and Demonstration Centre for Decentralised Sewage Treatment (BDZ) consists of primary school children aged between ten and thirteen. The project will enable them to discover basic concepts of ecology through fun experiments. The concepts covered will include water and nutrient cycles in nature and the potential of waste water as a valuable resource.

The focus is on developing an interactive demonstration system that will be set up and tested on-site at the Training and Demonstration Centre for Decentralised Sewage Treatment (BDZ) in Leipzig-Leutzsch. The project is being supported by BDZ members Kommunale Wasserwerke Leipzig GmbH (KWL) and UFZ. Teachers, and of course pupils, at the Leipzig International School (LIS) and the Adam-Friedrich-Oeser primary school in Leipzig are also playing an important part.


The demonstration in Leipzig-Leutzsch is designed to raise awareness of the water situation in newly industrialised and developing countries. Around the world, four million people – including children in particular – still die of diseases like diarrhoea, cholera and typhoid each year because of dirty drinking water, making the development and realisation of low-cost, simple solutions for sewage treatment a high priority.

Natural plant sewage treatment systems can play a role here, since they are capable of turning sewage into safe irrigation water. This method has been refined and optimised at UFZ within the Helmholtz Association of National Research Centres. “Natural plant sewage treatment systems can meet much of the high demand for water for irrigation farming in arid regions”, says Dr. Roland A. Müller of UFZ, explaining the benefits of the technology. “The nutrients contained in the sewage are retained and can be reused by the crop plants, thereby completing the natural cycle.”

As well as the demonstration at BDZ’s demonstration site in Leipzig, the project partners are developing classroom experiments which will be low cost and easy to assemble and can be maintained by the pupils themselves. The idea is for the teaching materials to motivate the children to ask questions about nature and for them to learn to understand natural processes by experimenting with ecosystems and interpreting their own observations and data. Since the demonstration and classroom experiments stem from ongoing research into near-natural systems, the children are assured of being exposed to today’s best available technology. A first test phase of the new teaching material and demonstration concept is planned for August 2006.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
