SNIPPET:

So many chemicals enter our water, often in tiny amounts. For example, pesticides from fields can run off into rivers, medicine is peed out into toilets, not to mention the chemicals produced by factories that enter rivers. With fresh water being increasingly scarce, it is important to have sources of safe, clean drinking water. One stumbling block is that it’s hard to remove small amounts of pollutants from water. Current methods use a lot of energy or chemicals. Now, researchers at MIT have created a very efficient method for removing even a tiny amount of pollutants from water. They use an electrochemical process that binds dangerous chemicals and lets clean water go through.

Taking out chemicals

MIT postdoc Xiao Su and a team of researchers at MIT and at the Technical University of Darmstadt in Germany developed this new method to remove contaminants from water. Even small amounts of these chemicals can be harmful if consumed through drinking water. The researchers were able to remove even very small amounts of pesticides, chemical waste, and pharmaceuticals with 96% success.


So here’s how it works:
