I previously wrote about Graphair, a graphene based water filtration system that would enable you to drink water straight out of Sydney Harbor. But now something even better may have come along. A new way to convert salt water into drinking water in only a few minutes using sunlight.
Science Alert explains how it works:
“A new innovation developed by scientists in Australia could be the most promising one yet, with researchers using metal-organic framework compounds (or MOFs) together with sunlight to purify water in just half an hour, using a process that’s more efficient than existing techniques.
It’s cheap, it’s stable, it’s reusable, and it produces water that meets the World Health Organisation (WHO) standards for desalination. Around 139.5 litres (nearly 37 gallons) of clean water can be produced per day from a kilogram (2.2 pounds) of MOF material, based on early testing.”
And best of all, “After just four minutes of exposure to sunlight, the material releases all of the salt ions it’s soaked up from the water, and is ready to be used again. The team behind the new process says it provides several upgrades over existing desalination methods.”
Yes, but does that assessment include a comparison to Graphair?! Either way, it’s exciting to see that we may be on the verge of getting a game-changing water filtration system up and running. For this is a technology with the potential to revolutionize the world.
Is a Metal-Organic Framework Filter the Greatest Idea Ever?
