Graphene sieve turns seawater into drinking water

A team of researchers in the UK has created a graphene-based sieve which can remove salt from seawater.

According to a report by the BBC, the sieve uses a graphene oxide membrane to filter out the salt – with holes in the sieve less than one nanometre in size (0.000001mm).

The invention will be tested against current desalination techniques and could prove hugely beneficial for people with limited access to drinking water.

The report stated that by 2025, 14% of the world’s population will encounter water scarcity and large-scale production of the graphene sieve may help address the issue.
