Seawater desalination, which is the process of desalination of seawater and separation of impurities. It is the process of converting seawater with high salt content into fresh water that can be used by human life and industry through technical means, and is one of the effective ways to solve the problem of global freshwater shortage. At present, the main desalination processes include distillation, electrodialysis, ion exchange desalination, etc. To a certain extent, these technologies can meet the water needs of coastal areas, islands and some inland water-scarce areas, but at the same time, they also face problems such as high energy consumption, large investment and environmental impact. Therefore, it is still important to develop efficient, energy-saving and environmentally friendly desalination processes and optimize water management strategies.
Reverse osmosis is a popular new desalination process, and the scale of development is expanding. Compared with the traditional seawater desalination process, the advantages of reverse osmosis are mainly reflected in low energy consumption, low pollution, stable water quality, low repeated investment cost, etc., so it has strong market competitiveness.
The reverse osmosis method mainly relies on the superior technology of reverse osmosis membranes. The operating principle of the reverse osmosis membrane is simple, and the seawater desalination and impurity separation can be started by using a high-pressure piston pump to drive the seawater into the reverse osmosis membrane system. The reverse osmosis membrane adopts nano-scale separation materials, with small pore size and tight arrangement, which can effectively intercept a large amount of salt, suspended solids, organic matter, colloids, microorganisms and other substances contained in seawater without high temperature and chemical reaction, and the effluent water quality is stable. Reverse osmosis membranes have a large membrane flux and good water permeability, so they can ensure high seawater treatment efficiency. It also has strong anti-pollution ability, is not easy to be polluted and clogged by impurities, is easy to clean and maintain, and can reduce repeated investment costs.
The reverse osmosis desalination process has realized the incremental development of high-quality freshwater resources and has broad development prospects. It can provide a reliable technical solution to the problem of water shortage in industrial production and people's lives, and will continue to be applied in practice for the benefit of social development.
