The filter media commonly used inside the multi-media filter are quartz sand, anthracite, manganese sand, etc. These media are distributed in a scientific and orderly manner in the filter tank according to their specific gravity and particle size.
For example, the anthracite with small specific gravity and slightly larger particle size is placed on the top layer of the filter bed, the quartz sand with moderate specific gravity and small particle size is placed on the middle layer of the filter bed, and the gravel with large specific gravity and particle size is placed on the bottom layer of the filter bed. Such a distribution can effectively ensure that the filter will not produce the phenomenon of chaotic layer when backwashing, thus ensuring the retention capacity of the multi-media filter media.
The above is the distribution of the filter media inside the multi-media filter, the multi-media filter media for reasonable distribution, not only can effectively improve the filtration capacity of the equipment but also for the equipment itself good maintenance and maintenance.
