Properties Of Water: The desalination process

The video discusses the global issue of water scarcity, highlighting efforts by organizations like UNICEF and WaterAid to provide clean water. It explains desalination, particularly reverse osmosis, as a method to remove salt from water. The potential of graphene in improving desalination efficiency is explored, with its unique properties allowing for effective water purification. The importance of freshwater for economic development and the challenges posed by population growth and climate change are emphasized.
