Abstract:

Water is an essential resource for life on Earth and therefore, securing adequate freshwater for all life and human activities is a premier and precondition aspect to achieve sustainable development. Many countries face water scarcity as a fundamental challenge to their economic and social development. Water use has been growing at more than twice the rate of population increase in the last century. Hence, proper water management and also desalination of water, in some countries, is necessary to meet the needs of water required. A desalination process essentially separates salts from saline water and makes the water usable. The two major types of technologies that are used around the world for desalination are either thermal or membrane technology. Both technologies need energy to operate and produce fresh water. The most widely used technique or process is Reverse osmosis (RO) membrane technology. But this method has some limitations. This paper aims at highlighting the drawbacks of the RO purification system and giving an alternative to that system. Nanoporous graphene is the proposed alternative to the present membranes used in the RO technology. Hence, this paper gives a comparison of the conventional RO membrane technology and the new innovative nanoporous graphene technology.
