Sand & Gravel

Description

A sand and gravel filter is a type of filtering system that is used to remove impurities from water by using a bed of sand or gravel to trap and remove contaminants. These filters are often used in domestic, industrial, and agricultural settings to purify water for drinking, irrigation, and other purposes.

Sand and gravel filters work by allowing water to pass through a layer of sand or gravel, which traps and removes suspended particles and other impurities. The size of the sand or gravel particles and the size of the pores between them determine the efficiency of the filter. Larger particles and wider pores allow more water to flow through the filter, but they also allow larger impurities to pass through. Smaller particles and narrower pores provide more effective filtration, but they also reduce the flow of water.

Sand and gravel filters can be used on their own or in combination with other types of filters, such as activated carbon filters or ultraviolet light filters. They are relatively low-cost and easy to maintain, and they are effective at removing a wide range of impurities, including bacteria, algae, and other microorganisms, as well as larger particles such as sand, silt, and sediment.

Product Description:

Filter gravel is used as a support media to filter sand and coal in water filters.
For maximum efficiency, filter gravel must possess the necessary attributes of hardness and be rounded rather than angular.
Filter Gravel is a hard, round, predominantly quartz aggregate. The filter gravel, like filter sand, contains hard durable particles with a slow breakdown rate. This helps to prolong filter media life.
