Researchers develop low-cost purification system that uses CO2 gas to clean water

The problem with most water purification methods is that they become clogged and need to be replaced over time. A new technology developed by researchers at Princeton University doesn’t require filters at all, instead relying on the injection of CO2 gas to change the water’s chemistry and Read More...

MIT scientists have developed low-energy process for cleaning polluted water

Scientists at MIT have created an electrochemical process able to selectively get rid of organic pollutants in water, which can be harmful even in minimal amounts. Typically, a lot of energy or chemicals are required to remove dangerous contaminants, but this new process is different, relying on a Read More...

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

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...
