German engineers have come up with a remarkable machine that turns sewage into charcoal.
If that was not enough of a feat, they say it helps the fight against climate change by locking up carbon from the sewage that would otherwise have gone into the air.
And to make it even more extraordinary, they are feeding the charcoal to plants and claiming that it helps them grow faster.

Although still not as widely accepted as in Europe and Asia, the use of ozone for water treatment has gained increased application in North America's plants, especially those dependent on large reservoirs, rivers and other surface sources for their raw water supply.
Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant-Disinfection Byproduct Rule (D/DB ... read more >>
A complex sugar may become one of the most effective weapons to stop the spread of cholera, a disease that has claimed thousands of lives in Haiti since the devastating earthquake last year. A technique developed by University of Central Florida scientists would allow relief workers to test water sources for contamination with the cholera toxin. ... read more >>
High-energy costs are one drawback of making clean water from waste effluents. According to an article in the journal Biomicrofluidics, which is published by the American Institute of Physics, a new system that combines two different technologies proposes to break down contaminants using the cheapest possible energy source: sunlight. ... read more >>
Hanufa Bibi stoops in a worn sari and mismatched flip-flops to work the hand pump on her backyard well. Spurts of clear water wash grains of rice from her hands, but she can never get them clean.
Thick black warts tattoo her palms and fingers, the result of drinking arsenic-laced well water for years. It's a legacy that new research has linked to one in five deaths among those exposed in Bangl ... read more >>
Hundreds of thousands of shimmering black plastic balls were dumped into one of the city's last open-air reservoirs to prevent a sunlight-fueled chemical reaction that can harm the water supply. ... read more >>
"Over the past six months we have extensively tested and demonstrated our portable water clarifier/purifier on the production of safe drinking water from unsafe sources," says Leonard Girard, Chief Science Officer with Purio. "Every demonstration, as previously reported, produced safe, delicious drinking water and so we have stepped up to the challenge of processing residential wastewater right o ... read more >>

The Environmental Protection Agency has decided there's no need to rid drinking water of a toxic rocket fuel ingredient that has fouled public water supplies around the country.
EPA reached the conclusion in a draft regulatory document not yet made public but reviewed Monday by The Associated Press. ... read more >>
Water is a precious natural resource and basic need sustaining the life of all living creatures. It cannot be produced or added electronically or hydrologically or by any other technology, though it can be recycled to some extent. On the earth, 75 per cent of surfaces are covered with water. Yet, people living in the remaining surfaces are suffering without potable water for their basic requireme ... read more >>
