Background
China is a country lacking in fresh water resources, the per-capita water resource possession is low, the space-time distribution is uneven, and in recent years, the seawater desalination industry in China has outstanding problems of excess capacity, idle equipment and the like. The over-growth of capacity, high production cost and insufficient market demand are direct reasons for the over-production of capacity.

The seawater desalted water has strong corrosivity, and cannot directly enter a municipal pipe network or be directly used as domestic water; if the water is to enter municipal pipe networks and be used as necessary supplement to domestic water, post-treatment is necessary.
At present, the mineralization technology for seawater desalination water mainly comprises two technologies: contact mineralization and medicated mineralization:
Contact mineralization method: fully contacting the acidified desalted water with the calcium carbonate-rich filler, and dissolving the calcium carbonate into the water.

Chemical addition type mineralization method: the method can improve the hardness and alkalinity of the desalted water by adding a certain amount of mineralized raw materials and adjusting the PH. The chemical-adding type mineralization method has the advantages of high speed, small occupied area and the like, but also has the defects of large turbidity of mineralized effluent, high raw material and operation cost and the like.
