Nano-scientists develop new kind of portable water purification system, could bring clean water to rural poor

Nano-scientists develop new kind of portable water purification system, could bring clean water to rural poor | "#Volunteer Abroad Information: Volunteering, Airlines, Countries, Pictures, Cultures" | Scoop.it

A water purification system that uses nanotechnology to remove bacteria, viruses and other contaminants may be able to deliver clean drinking water to rural communities for less than $3 a year per family, according to a new study.

 

Researchers at India's Institute of Technology Madras have developed a new kind of portable water purification system based on nanoparticle filtration. In their paper published in the Proceedings of the National Academy of Sciences, the team explains how their new device does its job—it employs nanoparticles to remove not just biological hazards, but toxic heavy metals as well. The system they have developed is a two-stage filtration process that provides 10 liters of clean water in just an hour's time.
