Sand and coal are supported in water filters by a form of filter media called filter gravel. Because of its capacity to contain precipitates containing contaminants, it is a powerful filter media. Filter gravel must have the essential characteristics of hardness and be rounded rather than angular for best effectiveness. Similar to filter sand, filter gravel comprises tough, long-lasting particles that degrade slowly, extending the life of the filter media.
The physical and mechanical qualities of filter gravel define its characteristics. The particle’s size and shape have a significant impact on how well the filter material works. For filter gravel, the recommended size range is 2 mm to 5 mm. The porosity and permeability of the filter bed are impacted by the roundness of the particles. This is another crucial factor.
In conclusion, because filter gravel can retain precipitates that contain pollutants, it works well as a support media for water filters. Its composition varies depending on the source, but for best effectiveness it must have the appropriate characteristics of hardness and be rounded rather than angular. The porosity and permeability of the filter bed are influenced by the roundness of the gravel particles, which should have a size range of 2 to 5 mm.
