The working principle of the multi-media filter is mainly through the use of more than two kinds of filter media, under a certain pressure, so that the water with higher turbidity through a certain thickness of granular or non-granular materials, so as to effectively remove suspended impurities, so that the water is clarified. Commonly used filter materials include quartz sand anthracite, manganese sand and so on
The multi-media filter material in the filter is high-quality homogeneous gravel, quartz sand, magnetite, anthracite and other filter materials,Filtering Equipment which are scientifically and orderly distributed in the filter tank according to their specific gravity and particle size, such as anthracite with small specific gravity and slightly larger particle size is placed on the top layer of the filter bed, and quartz sand with moderate specific gravity and small particle size is placed on the middle layer of the filter bed. Gravel with large gravity and particle size is placed in the bottom layer of the filter bed. This ratio ensures that the filter will not produce chaotic layer phenomenon when backwashing, thus ensuring the retention ability of the filter material.

The filter material of multi-media filter (including double filter material filter) should have sufficient chemical stability, the relative density and particle size of each medium should have certain differences,Environmental Protection Equipment and the relative density of anthracite used in the double-layer filter material filter composed of anthracite and quartz sand is 1.4-1.6, the particle size is 0.8-1.8mm, and the relative density of quartz sand is 2.6-2.65. The particle size is 0.5-1.2mm; In addition to the above two filter materials, heavy ores such as manganese sand and magnetite can also be used, with a relative density of 4.7-5.0 and a particle size of 0.5-4mm.
Sewage treatment equipment: effective treatment of domestic sewage and industrial wastewater, to avoid sewage and pollutants directly into the water, to improve the ecological water environment is crucial.
At present,Environmental protection chemical equipment China's environmental protection equipment has formed a certain scale and system in the three major fields of air pollution prevention and control equipment, water pollution treatment equipment and solid waste treatment equipment. 2017-2020 China's environmental protection equipment market size from 343.81 billion yuan to 378.94 billion yuan, the average annual compound growth rate. China Business Industry Research Institute predicts that China's environmental protection equipment market will reach 414.66 billion yuan in 2023.
