Sieve turns sea water into fresh water

April 13, 2017

UK-based team of researchers has created a sieve capable of removing salt from seawater.

This new product could help millions of people without ready access to clean drinking water.

The team have created a new material called graphene membranes. These membranes are very strong and can conduct electricity.

To make it permeable (allowing liquid to pass through), they then drill small holes in the membrane and create a sieve. But the hole has to be very small to prevent salt to go through. If the hole size is larger than one nanometre it doesn’t work and the salt goes through.

A nanometre is equal to one billionth of a metre (0.000000001 m).
