A Saudi Arabian company has won the Guiness World Record for having the lowest energy consumption of a water desalination plant.

The Saudi Water Conversion Corporation (SWCC) set the record by using reverse osmosis technology, which uses pressure to force water through a membrane, effectively filtering out the salt without having to heat up the water.

Advances in technology in the last two decades, including new membranes that require less water pressure, have led to a more widespread use of reverse osmosis in desalination.
