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 >>
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.

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 >>
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 >>
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 >>
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 >>
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 >>
Hundreds of workers laid 17 floating dams on the Wei River in China to contain an oil spill. A pipeline from China National Petroleum Corp. last week started leaking into the waterway, which feeds into the Yellow River. Chinese officials shut down six generators at a Yellow River dam to contain the spill, estimated at 100 tons of diesel fuel. ... read more >>
Queensland University of Technology (QUT) researchers have developed new technology capable of removing radioactive material from contaminated water and aiding clean-up efforts following nuclear disasters. ... read more >>
