Wrekin Water Gravel - 5-8mm (washed)

Filter gravel is a coarse, granular material used in water filtration systems to provide a support structure for the filter media and to distribute water flow evenly. It's typically placed at the bottom of a filter bed, beneath the filter media such as sand or activated carbon.

Choosing the Right Filter Gravel:

•  Particle Size: The particle size of the gravel should be larger than the filter media to allow for proper water flow.
•  Washed: Washed gravel is generally preferred for filtration applications to ensure consistency and prevent clogging. 
•  Quantity: The amount of gravel needed will depend on the size of the filter bed and the desired filtration rate.

Applications of Filter Gravel:

•  Residential Water Filtration: Used in whole-house and under-sink filtration systems.
•  Municipal Water Treatment: Employed in large-scale water treatment plants.
•  Industrial Water Treatment: Used in various industrial processes to filter and purify water.
•  Aquarium Filtration: Employed in aquarium filters to provide a support structure for the filter media.

Filter gravel is an essential component of many water filtration systems. By selecting the appropriate type and size, you can ensure optimal filtration performance and longevity.
