Seawater desalination has been widely recognized by many countries around the world as a technology for the incremental development of freshwater resources, and its advantages and development prospects have been fully demonstrated in practice. In China, the development value of seawater desalination is high. There are many coastal cities in China and a number of important export ports. The steady development of industrial production in coastal areas is essential for the growth of exports. Therefore, by solving the problem of water shortage in coastal areas, we can greatly improve the export capacity of industrial products in China's coastal areas, which is of great importance to economic development.
Small seawater desalination equipment is an ideal choice to solve the problem of water shortage in industrial production due to its small size, stable water quality and high production efficiency. It takes reverse osmosis membrane as the core technology, which is simple to operate, short in process flow and low in failure rate. When the small seawater desalination equipment is running, it can realize the separation and treatment of impurities such as salts, organic matter, colloids, microorganisms, bacteria, metal ions, suspended solids and other impurities dissolved in seawater by driving seawater into the reverse osmosis membrane unit by relying on pressure.
Reverse osmosis membranes have nano-scale separation capabilities, and are resistant to fouling and are not easy to clog. Therefore, its application can fully reduce the risk of damage to small desalination equipment, reduce the frequency of cleaning, and prolong the service life of the equipment. The reverse osmosis membrane provides important technical support to ensure the effluent quality of the small seawater desalination equipment, so that the effluent water quality of the equipment can meet the relevant standards, safe and reliable.
The operation of small seawater desalination equipment is less affected by time, space and climate, and the operation is stable and continuous, and automatic production can be realized without special supervision. It is mainly composed of water intake system, pretreatment system, seawater desalination and desalination system, chemical cleaning system and intelligent control system, which has strong intelligence, fast water production speed, not easy to scale, low energy consumption, and has a high investment cost performance.
