MIT researchers develop new way to clear pollutants from water
When it comes to removing very dilute concentrations of pollutants from water, existing separation methods tend to be energy and chemical-intensive. Now, a new method developed at MIT could provide a selective alternative for removing even extremely low levels of unwanted compounds. The new Read More...
Researchers develop low-energy process for filtering water using carbon
Filtering mass-amounts of water can be an energy-intensive process, but that could soon change thanks to a team of researchers. Using carbon dioxide resumes, the researchers developed a new process that requires one thousand times less energy to remove suspended particles and bacteria from water. Read More...
'Electric' bacteria can purify sewage water
Harnessing bacteria that produce electricity and break down organic waste, a European research project is developing a new, environmentally friendly way to purify sewage water in small communities. It may look like a park, but an experimental plant in Carrión de los Céspedes, near Read More...
Here's why African cities could lead in water innovation
Tuesday, April 25, 2017 - 1:45am For sub-Saharan Africa, water long has been something of a paradox. On the one hand, it is the source of some of the continent’s worst PR. Water in Africa rarely appears on the global stage except when there isn’t enough of it — as in the Read More...
This device uses the sun to pull clean drinking water out of desert air
In Kenya, where a three-year-long drought was declared a national disaster in February, getting a drink of water can mean walking five miles or more to a well that may or may not be dry. A new device under development now shows how someone in a future drought–or the hundreds of millions Read More...
This non-profit helps people pay their overdue water bills
Isn’t it inhumane that those who can’t afford to pay their water bills can have their water supply shut off? The nonprofit organization The Human Utility thinks so. That's why they have built a website to connect donors with people in need. With some documents like paystubs, people with overdue Read More...
These artificial ice glaciers are solving the water crisis in the Himalayas
High temperatures and minimal rainfall have left the Himalayas bone-dry. To solve the water shortage, an engineer has come up with an ingenious solution called the “ice stupa”, an artificial glacier. Melted water from existing glaciers is diverted underground through pipes that lead to the Read More...
Most people: 'You can't drink water out of thin air'. Scientists: ‘Watch this'
You probably enjoyed a nice shower this morning (you are taking cold ones, right?!). Maybe you're tipping back a bottled water without much of a care except your smartphone calendar pings. But around the world, those scenes often are a true luxury, with some 783 million people lacking traditional Read More...
One key way soggy California could save water for the next rainless days
The water spread into every corner of the fields, beckoning wading ibises and egrets as it bathed long rows of sprouting grapevines. Several inches had covered the vineyard ground for a couple of months. But rather than draining it, Don Cameron was pouring more on. “This is not about Read More...
MIT creates tool that may end thirst, even in the desert
As summer begins to heat up across most of the United States, one issue that doesn't seem to go away is drought--especially in dry or desert climates. Deserts make up a third of earth's surface (and oceans are 71%). Neither of these environments has traditionally been easy to live in, in large part Read More...
