A more efficient way to turn saltwater into drinking water?
Water insufficiency may be a major drawback across the globe. “It affects each continent,” says amir Barati Farimani, associate degree prof of engineering science at Carnegie philanthropist University. “Four billion folks live beneath conditions of severe water insufficiency a minimum of one month of the year. half a billion people live beneath severe water insufficiency all year.”
There square measure some ways to desalinate water, however one among the foremost effective is membrane chemical process. during this technique, water is pushed through a skinny membrane with small holes. The water flows through the pores, however the salt ions cannot, going away solely water on the opposite facet.
In his latest analysis, Barati Farimani explores the potential of a replacement sort of membrane, known as a metal-organic framework (MOF). “These membranes comprises each the metal center and compound,” Barati Farimani says. The compound and metal connect during a pentangular pattern, going away a hole within the center that is a pore. “If you explore them, they are sort of a honeycomb,” Barati Farimani adds.
There square measure a couple of reasons why the framework is more practical. First, it’s improbably skinny. it is a few atoms thick, which implies there is little friction because the water molecules experience the pores.
