New technology uses less water and produces energy and fertilizer at same time

Baku, April 27 (AzerTAc). Water is a valuable resource. New technologies are making it easier to handle drinking water responsibly, purify wastewater effectively and even recover biogas and fertilizer. Fraunhofer researchers will be showing how this is done at the Hannover Fair (23 - 27 April) in the House of Sustainability.
Clean drinking water and basic sanitation are human rights. Yet almost 780 million of the world`s population still have no access to drinking water and some 2.6 billion people live without sanitary facilities. Water, though, is also an important economic factor: Today, agricultural and manufacturing businesses already use up more than four fifths of this precious commodity. And the demand for water continues to rise. The Organization for Economic Cooperation and Development (OECD) is expecting that by 2050, global water consumption will have risen by more than half. Some 40 percent of the world`s population will then be living in regions with extreme water shortages -- 2.3 billion people more than today.
We have, to date, been wasteful in our use of this valuable resource. In Germany, each and every individual consumes around 120 liters of water per day -- they drink only three. Another third is flushed down the toilet. But in some regions of the world, clean water is much too precious to be wasted transporting excrement. New technologies are allowing us to significantly reduce drinking water consumption, purify wastewater effectively and even recover biogas and fertilizer. The researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and System and Innovation Research ISI have developed the solutions as part of the DEUS „Decentral Urban Water Infrastructure Systems" project.
