Gas Hydrate, a promising candidate in water treatment : Review

In the current era of modernization, environmental resources are being continuously a ffected in an adv manner. The pollution of water through anthropogenic activities is the critical factor in the loss of freshwater resources. The desalination technologies are used worldwide and are becominga principle mean of getting clean water. Generally fossil fuels are used as an energy source to operate the desalination plants and result in high energy consumption and environmental hazards. The gas hydrate desalination and wastewater treatment are the impending techniques which not only can handle wastes but also provide an economic, less toxic and feasible purified water. In this article, the authors summarized the current knowledge about the properties, advantages/disadvantages, formationcontrol mechanism and applications of gashydrates. The purpose of this review is to encourage further research on the undiscovered aspects of gaseous hydrates in water treatment through a biocompatible approach.
