New filtering method promises safer drinking water

This application could prevent fluoride toxicity in water supplies

Researchers from the Tufts University School of Engineering have developed a new filtering technology for water and it is inspired by biology. This new technology could help reduce the drinking water-related disease which affects millions of people all over the world. It has the potential to improve environmental rectification, industrial and chemical production, and mining.


The researchers demonstrated that their new method which uses novel polymer membranes can separate fluoride from chloride and other electrically charged atoms more efficiently.


This application could prevent fluoride toxicity in water supplies and change the elements which are suitable for human consumption. It is widely known by scientists and researchers that adding fluoride to a water supply can reduce tooth decay and cavities but very few people know the fact that high levels of fluoride can lead to severe health problems.

The consumption of excess fluoride can cause fluorosis leading to weak teeth, calcify tendons and ligaments and also bone deformities.


WHO says that excessive fluoride intake through drinking water has caused problems to millions of people.


The ability to remove fluoride can protect from fluorosis without needing the use of high-pressure filtration or removing the suitable minerals.


This work was funded by the Cambridge based company named Zwitterco. They will again research to test their application in industrial settings.
