How much is the head loss 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

How to put the fish tank filter? 1.Level 1: Physical filtration level: place fiber cotton (note: socks can be used to filter out suspended solids and clear them at the outlet pipe mouth, which is convenient to wash ).2.The second level: chemical filtration grade: Place chemical adsorption filter materials such as activated carbon, ammonia-absorbing Stone, zeolite, clear water resin (the adsorption effect of such filter materials is generally only three months after expiration must be changed ).3.Level 3: biological filtration level 1: place biochemical cotton (note: it is better to choose the size of the aperture with high strength and high elastic filtration rate ).4.Level 4: biological filtration level 2: Place biochemical balls (note: the capacity of this level is as large as possible ).5.Level 5: biological filtration level 3: place the porcelain ring (note: The higher the water absorption rate of the porcelain ring, the better the higher the surface roughness ).6.Level 6: biological filtr
