Freshwater resources are indispensable basic resources for maintaining social and economic development, and the shortage of freshwater resources will have a great impact on the production capacity and level of industry. In addition, freshwater resources are also essential resources to ensure people's livelihood, and people's daily activities are inseparable from fresh water. However, China is also a country with a shortage of fresh water resources, and there are still relatively prominent water pollution problems that need to be solved urgently. Therefore, the development of seawater desalination technology to increase freshwater resources reserves is an important way to alleviate the problem of freshwater resource shortage.
Seawater desalination equipment is a reliable technical achievement to realize the transformation of seawater into fresh water, which can "replenish water" for economic development and stability. The freshwater it produces is hygienic, safe and reliable.
Reverse osmosis membrane technology is used as the core technology in seawater desalination equipment. The reverse osmosis membrane operation is driven by pressure, and the seawater passes through the reverse osmosis membrane carried in the equipment by pressurizing the high-pressure plunger pump, because the reverse osmosis membrane can realize the separation of nano-scale substances, so it can effectively intercept salt, colloids, microorganisms, organic matter, suspended solids, metal ions and other substances in the seawater, so as to ensure the large pass rate of water molecules and the stable water quality of the effluent.
The operation of seawater desalination equipment is basically not limited by time and climate, and can be operated continuously and automatically. It is mainly composed of water intake system, pretreatment system, seawater desalination and desalination system, chemical cleaning system and intelligent control system, which can provide fresh water resources for offshore operations, coastal industrial production, island areas and other stable water, with the advantages of simple operation, energy saving and environmental protection, fast water production speed, not easy to scale and cause equipment blockage, low operating cost and so on.
Through the development of seawater desalination equipment, the problem of water shortage for economic development can be solved to a large extent. Of course, while developing more freshwater resources, we cannot ignore the protection of existing water resources and water pollution control. Sustainable economic development can only be achieved if conservation and development go hand in hand.
