silica sand filter media
Appearance: white granular
Standard: GB/T6166--1985
Other name: quartz sand
Raw material: high quality natural quartz mineral (silica mineral)
Production process:
select high quality quartz mineral, crush, wash, screen, acid-washing, stoving and rescreen.
Features of silica sand:
1. High mechanical strength
2. Stable chemical performance
3. Without impurities and high wear resisting
4. High effciency in water filtration and long time service
5. Silica sand widely used in single-layer and double-layer filter pond
6. At present silica sand is the most widely used and the most popular filter media in water purification
