Sustainability Problem
80% of illnesses are linked to poor water and sanitation conditions in developing countries and 1 out of every 5 deaths under the age of 5 worldwide is due to a water-related disease.
Technology Article
- Researchers have developed a graphene water filter that could provide fresh, safe drinking water to people around the world.
- The filter cleans water 9 times faster than current filters and is able to filter out bacteria and viruses.
- Until now, graphene water filters have been expensive and hard to produce on an industrial scale.
- By creating a viscous graphene oxide, the researchers have given way for the opportunity to filter water on a large scale.
Stakeholders
- Researchers who created the graphene water filters
- People in need of clean water
- Companies who invest in the technology and produce it on a mass-scale
Deployment
- The filter enters the commercial market.
- Through donations or public-private partnerships, the filters are sent to developing countries where clean water is needed.
- The filters are distributed to people in need.

This is a very cool and significant development. Thank you for sharing this. Nanofilteration is definitely the way forward to make clean water easily accessible.
Taking it a step further, I am sure commercial markets can be set up in developing nations (with a lower cost aspect), instead of relying on donations alone. This could possibly turn into a financially sustainable business model.

Great application of graphene! Graphene is a two-dimensional monolayer (consisting of a single layer of atoms) material which is stronger than steel and harder than diamond. As well, being transparent and light, it has a great potential as tools for technologists!
