Seawater is an important component of marine resources and a vital supplement and reserve source for freshwater resources. Developing the seawater desalination industry is an effective way to increase resources and fundamentally solve the problem of water scarcity.

The research on seawater desalination technology in China began in 1958, initially using electrodialysis technology, and gradually shifted to reverse osmosis technology and distillation technology. Reverse osmosis membranes have the characteristics of high flux and high water production, which can effectively remove harmful components such as inorganic salts, heavy metal ions, organic matter, and bacteria from seawater. Combining the high-quality performance of reverse osmosis membranes with automated and high-precision manufacturing processes can save investment and operating costs of seawater desalination systems, and increase the system's water production capacity.

The development of membrane technology began in the 1960s. The principle of reverse osmosis membrane seawater desalination technology is to filter out fresh water by passing pre treated seawater through a polymer membrane under high pressure. The reverse osmosis membrane method has gradually gained advantages such as low investment, low energy consumption, low cost, and short construction period, and has broad development prospects.

By adopting reverse osmosis membrane technology, the energy consumption of seawater desalination can be effectively reduced, ensuring a long service life and low maintenance costs of the system. The effluent quality of the system is stable for a long time and can pass national testing and certification. In addition, the reverse osmosis seawater desalination system is based on a modular design concept in terms of spatial and technological utilization, which makes the spatial configuration more reasonable, construction more convenient and efficient, and can simultaneously meet different needs.

The pore size of reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. from water. The cleaning treatment of reverse osmosis membranes is a meticulous and tedious task. Currently, the quality of domestically produced membranes is not high enough, and multiple cleaning of membranes can easily damage them. In order to reduce cleaning work, it is necessary to do a good job in pre-treatment and ensure the quality of water.
