Clathrate hydrates are gaining interest in their applications in the area of energy and the environment. They are also being considered for recovering clean water from brackish water, seawater, wastewater, and industrial effluents. Water reclamation via clathrate hydrate is based on the formation, separation, and dissociation of hydrate crystals devoid of salt and metal ions from saline/wastewater. A comprehensive review of studies undertaken to date on the application of clathrate hydrates as promising carrier for water desalination/treatment is presented. Both fundamental and technological advancements in the clathrate hydrate technology are reported to establish its feasibility and potential for producing quality water from waste effluents. The hydrate forming agent and kinetic promoters have been found to be important factors for faster hydrate formation and subsequent water recovery. Several developments towards novel reactor design, efficient separation & washing methods, hybrid hydrate-membrane processes, multi-functional devices etc. present a strong case for considering the clathrate hydrate technique as an available alternative for water reclamation in near future.

笼形水合物在能源和环境领域中的应用引起了人们的兴趣。还考虑将它们用于从微咸水，海水，废水和工业废水中回收清洁水。经由笼形水合物的水回收是基于不含盐和金属离子的水合物晶体从盐水/废水中的形成，分离和离解。介绍了迄今为止对包合物水合物作为水脱盐/处理的有希望载体的应用进行的研究的综述。据报道，笼形水合物技术的基础和技术进步都证明了其可行性和潜力，可以从废水中生产出优质水。已经发现水合物形成剂和动力学促进剂是加快水合物形成和随后的水回收的重要因素。在新颖的反应器设计，有效的分离和洗涤方法，混合水合物-膜工艺，多功能装置等方面的一些发展为考虑将包合物水合物技术作为近期水再生的替代方案提供了有力的案例。
