Breakthrough technology purifies water using the power of sunlight

Posted by in categories: particle physics, sustainability

A global research team has been able to transform brackish water and seawater into safe, clean drinking water in less than 30 minutes using metal-organic frameworks (MOFs) and sunlight.

In a discovery that could provide for millions of people across the world, researchers were not only able to filter harmful particles from and generate 139.5L of clean water per kilogram of MOF per day, but also perform this task in a more energy-efficient manner than current desalination practices.

The World Health Organization suggests good quality drinking water should have a total dissolved solid (TDS) of 600 parts per million (ppm). Researchers were able to achieve a TDS of 500 ppm in just 30 minutes and regenerate the MOF for reuse in four minutes under sunlight.
