GAS HYDRATE IN WATER TREATMENT Explores current progress in the expanding field of gas hydrate-based desalination As potable water shortages continue to affect billions of people worldwide, seawater desalination and wastewater treatment have the potential to meet freshwater demands in the near future. Gas hydrate-based desalination, a process which requires CO2 and water as solvent, has become an increasingly popular approach—desalination with hydrates is environmentally friendly and can produce cheaper desalted water than other existing conventional technologies. Gas Hydrate in Water Treatment: Technological, Economic, and Industrial Aspects provides detailed, up-to-date reference to the application of gas hydrates in wastewater and seawater desalination treatment. Edited by experienced researchers in the field, this comprehensive volume describes the fundamental aspects of desalination and summarizes the latest research on gas hydrate-based desalination. The authors address a broad range of key topics, including issues related to water scarcity, post-treatment of desalinated water using both conventional and new technologies, hydrate-based desalination methods driven by renewable energy sources, and more. <ul><li>Provides thorough coverage of the technological, waste brine management, economic, and renewable energy and remineralization aspects of gas hydrate-based wastewater treatment</li> <li>Describes the energetic, economic, and environmental impact of gas hydrate desalination</li> <li>Explains the core concepts of gas hydrate-based desalination to help readers evaluate the performance of existing desalination processes</li> <li>Discusses the advantages and challenges of hydrate-based water treatment</li> <li>Compares conventional and gas hydrate technologies used in water treatment</li> <li>Reviews the most recent research in gas hydrate-based desalination</li></ul> Gas Hydrate in Water Treatment: Technological, Economic, and Industrial Aspects is an essential resource for all academics, researchers, process engineers, designers, industry professionals, and advanced students in the field.
