A mobile organic waste purification unit developed by EUREKA project E! 3105 HYGICLAIR C100 can effectively treat human waste in recreational or crisis situation involving a large displacement of people. The first order of units is expected to be supplied to the French army around the beginning of 2008.
The system developed by the Austrian and French partners can cater for populations of 100 to 1800 people and be left in place for weeks or months. It uses biological processes to remove contaminants from human waste. The purpose is to produce a generally homogeneous treated effluent and a solid waste or sludge which are both suitable for discharge or reuse back into the environment.
Each unit is based in a portable standard 20ft container which can be quickly loaded and mobilised by truck, plane or ship. Effluent and waste from chemical toilets is pumped through a series of tanks which sort, treat and aerobic stabilise the waste, reproducing in miniature the larger systems that are used in cities. Connected in parallel, they can cater for an overall population of 1800. The containers have a low energy consumption of 35 kWh of energy per day and can also be configured for remote monitoring. Run almost automatically, the system needs about an hour of simple maintenance each week.
The project took the French company Sanitec SAS and two Austrian firms, Oko and Aim (Allegmeine Industrie-Montagen) 24 months to complete, and finished in September 2006. “Because of its mobility and its modularity, the system can be used for gatherings in isolated places” says Jean-Louis Faverot, member of the Conseil de Surveillance for French project partner Sanitec SAS. “It can equally be used for the specific treatment of effluents in isolated zones such as for the breeding of animals.”
“Without EUREKA, neither our Austrian partner, nor Sanitec, could have researched and produced the prototype or carried out the tests which had to be undertaken,” stresses Faverot.More information: Bernard Bolze and Jean-Louis Faverot

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...
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...
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...
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....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
