Which system is the marine desalination device composed? Whether it's desalination,Or saltwater desalination,Water supply pretreatment is the key to ensure the long-term stable operation of reverse osmosis system.In the development of seawater pretreatment programs, it should be fully considered that there are a large number of microorganisms, bacteria and algae in seawater.The reproduction of bacteria, algae and the growth of microorganisms in seawater will not only bring a lot of trouble to the water intake facilities,It will directly affect the normal operation of seawater desalination equipment and process pipelines.Periodic high tide, low tide,There is a large amount of sediment in the sea,The turbidity changes greatly,It is easy to cause unstable operation of seawater pretreatment system.Seawater is highly corrosive,The materials of equipment, valves and pipe parts used in the system should be screened to a certain extent,Good corrosion resistance.Foreign seawater desalination projects

Filter height of mechanical filter Introduction to adaptive and efficient mechanical filtersThe adaptive high-efficiency mechanical filter adopts the adaptive fiber filter as the core application technology. the filter material used uses the theoretical physics principle-nonlinear scientific fractal structure, and the advantages are self-adaptability and fractal structure. It not only has the efficient filtration accuracy of the fiber filter material, but also has the advantages of using the particle filter material backwashing cleanliness and low water consumption, the pore distribution of filter bed formed by using this filter material is basically close to the ideal filter layer structure. when filtering, the filter material will gradually decrease from large to small along the direction of water flow, and the void ratio distribution in the same section is more uniform, the water flow is consistent in size when filtering.When filtering, due to the poor proportion of the core and the fibe
