Water is very essential for all living beings. It covers nearly 70% of the earth’s surface. Even though the major portion of the earth is covered by water, there is a severe shortage of drinking water in most of the countries across the world. Safe drinking water is vital for all forms of life though it does not provide any calories. Desalination of seawater appears as a solution to this problem. Advanced desalination technologies that are applied to seawater and brackish water prove to be effective alternatives in a variety of situations. Desalination has a main role in obtaining reliable freshwater supplies from challenging water sources. This work mainly focuses on upcoming trends in modern desalination technologies and emphasizing the options offered by them. Desalination is a technique where the excess salts are removed from seawater or brackish water converting it into safe potable or usable water.
