Seawater desalination is the process of removing impurities such as salts and minerals from seawater, so that seawater becomes fresh water. The importance of desalination lies in the fact that it can solve the problem of water scarcity in many parts of the world. In arid areas, islands and coastal areas, freshwater scarcity has become a serious problem. The development of desalination provides a viable solution for these regions, which can greatly increase the amount of freshwater resources in these regions, thereby promoting economic development and improving people's livelihoods. In addition, desalination can be used in industrial and agricultural production, providing the water needed by many industries. Therefore, the importance of desalination cannot be ignored and is an important part of global water management.
The maturity of the seawater desalination process is not achieved overnight, but also developed through repeated research and experiments by researchers. Most of the early desalination technologies were distillation and electrodialysis, as well as refrigeration, which has been phased out. This type of method has insufficient removal rate of impurities in seawater, and even consumes a lot of energy, which requires a large amount of capital and energy cost investment.
In contrast, the reverse osmosis desalination process has made more significant progress. It takes reverse osmosis membrane technology as the core process advantage, and realizes the screening of impurities and water molecules such as salt, colloid, organic matter, microorganisms, suspended solids and water molecules in seawater by using the excellent interception ability of reverse osmosis membrane for ionic substances. Reverse osmosis membrane can function without high temperature and chemical reaction reagents, and is a physical filtration method, so it has low energy consumption and low capital cost requirements.
The reverse osmosis desalination process is stable and continuous, limited by time, space and climatic conditions, and fully capable of adapting to the complex and changeable climate change in coastal areas. Its operation has the ability to automate, which can save the input of labor costs. Therefore, compared with the traditional seawater desalination process, the production efficiency of the reverse osmosis desalination process has been greatly improved, the cost input is also lower, and the development prospect and market application potential are huge.
