Water filtration uses graded, high-purity silica sand as a filter medium to trap contaminants. It works because of its uniform particle size, chemical stability and durability. Shiv Mines and Minerals supplies filtration-grade silica sand to a specified particle size.
Why silica sand works as a filter medium
A uniform, well-graded sand bed removes suspended particles consistently and does not break down when exposed to typical water chemistry, making it a reliable filtration medium.
Where it is used
Filtration-grade silica sand is used in:
- Municipal and industrial water treatment plants
- Rapid gravity and pressure sand filters
- Swimming pool filters
