The Technological Development of Flash Desalination: Innovations and Future Prospects

Flash desalination is one of the well-known desalination processes belonging to the class of thermal desalination processes which has great potential to overcome the problem of water scarcity in the world. Although conventional flash desalination can be used to treat large amounts of water, it has some important issues to overcome regarding energy consumption, system efficiency and environmental effects. This review summarizes the latest technological development that seeks to address these limitations, including energy-saving technologies, integration with renewable energy technologies, and modification of the design for improved operational performance. It also assesses environmental factors, including the reduction of carbon footprint and management of brine. This paper presents a systematic analysis of the various approaches and examines some of the new hybrid systems and identifies gaps in the literature and ways of implementing them on a scalable and sustainable basis. The analysis offers a holistic view of the state-of-the-art and outlines strategic pathways for future research, with a focus on future desalination technologies that could potentially satisfy the increased demand for freshwater in the coming years.
