As the General of Assembly on 28 July this year clean drinking water and basic sanitation are resolved Menschenrechte.Leider there is more than a billion people around the world have no access to drinking water, while more than 2.6 billion people without sanitary systems at all life - this is more than a third of the world population.
Not only that water is an outstanding economic factor because agriculture and industry consume more than four-fifths of this precious commodity these days.A United Nations study indicates that in future water importantly policy.this because strategically than oil, why 14 Fraunhofer institutes in the Fraunhofer Alliance SysWasser to use come together with sustainable water system technologies be unveiling "Research for tomorrow's water use" in Hall A4, stand 302 201 the IFAT Entsorga fair.
Drinking water from the air
Drinking water can extract be from moisture in the air, even in the desert or in the Middle a megacity which is a technology developed by Fraunhofer required.the possible principle behind a saline solution, a tower-shaped system runs and absorbs water from the air. The hygroscopic brine is then pumped into a tank that stands a few meters tall and contains a vacuum.Then energy from solar panels condenses the brine is heated and verdunsteten salt free water brine is about a distillation Brücke.Die focused again and flows on the surface of the tower to absorb moisture in the air.
This process is based exclusively on renewable energy sources such as simple solar collectors and photovoltaic cells, which means that this method is totally energy self-sufficient. This means that it in areas functions where there no electrical infrastructure. This process is particularly suitable for the production of drinking water in arid and semi-arid areas where more water evaporates as precipitation falls.
Managing drinking water systems
How can we work best drinking water supply systems?There are leaks in the line system? HydroDyn management solution developed the researchers at the Fraunhofer together with drinking water suppliers, answers to these questions to give first of all, that collects drinking water system and modeled in the computer because that is the best way to find the optimal operational regime for these systems, or plan, such as schemes to extend over, the system can automatically locate leaks. This is the reason why this solution already in Mongolia, Libya and Saudi Arabia and at the Faculty is used for plants in several German cities.
Tracking down leaks
"There is a specific part of our precious water that gets to the consumer because of the leaking pipes and rust and instead it seeps into the ground unused.""Intelligent" probes that are check lines indoor track one of the ways Schaden.Risse or damage due to corrosion in the pipes can be localized with long-range ultrasonic waves, and these systems are ideal for fresh water and waste water pipes as well as for pipelines.
Diamonds clean wastewater
Diamond coated electrodes make it possible clean water without Chemie.Die idea is that hydroxyl radical in the water on electrodes coated with conductive diamonds formed rights.the highly effective oxidizing agents destroyed all substances that contain carbon, i.e. the organic pollution load of solvents to bacteria and pesticides.The only things that remain are harmless salts and carbon dioxide as gases to escape.This is how we can produce germ-free water without any problems.Researchers will demonstrate how this technique on your exhibition stand am Beispiel textile dye indigo Carmine works because the discolored water color in an electrochemical cell with diamond electrodes can be easily removed.
Money saving disposal
Heavy metals, cyanide salts, solvents and complex chemical connections-has eliminated heavily polluted waste water from the metallurgical or pressure constantly as hazardous waste in a costly process sending problem is the fact that pollution is strongly diluted with the share of water, sometimes as less than 90% and still mehr.Das makes it very expensive to entsorgen.Dies is why scientists at the Fraunhofer modular vacuum evaporation process have developed a low cost, where wastewater thickened in a vacuum at temperatures can waste water approx. 40 °-50 ° c required.the easily heats with waste or solar heat and desalinized water can be reused in the production.
More biogas from sewage sludge
More than 10,000 wastewater treatment plants clean the contaminated water from households, factories and restaurants in Deutschland.Das is clean water again in the rivers and Lakes released, and is the only thing that remains the use of Kl?rschlamm.Forscher at the Fraunhofer have engaged in a process to reduce the size and the mass of sewage sludge with a part of sludge with ultrasound and then mechanically zerfiel.Die deliver residues are processed in this way more biogas, which means that you are more easily drained can. this new process has been applied successfully to sewage treatment plants.
These and other solutions for sustainable water supply to your booth are researchers at the Fraunhofer werden.In presents addition the Fraunhofer water systems Alliance "Research for tomorrow's water use" in a seminar 4 pm presented September 16 in the Forum Hall B1.
