Red Flint Sand and Gravel Water Filtration Media - Maximum turbidity entrapment and low acid solubility

Red Flint Sand and Gravel water filtration media is a naturally clean filtration media found in Eau Claire, Wisconsin, the land of clear water. Our filter media is useful for applications such as pool sand and filter sand.

The glacial deposit media has an increased surface area that provides better particulate holding capacity, thereby:

  • Improving particle removal while still providing maximum
    water flow.
  • Allowing for deeper particle bed penetration.
  • Increasing filter run time.

General Properties of Red Flint Water Sand and Gravel Filtration Media

  • Sub-angular shape provides for maximum turbidity entrapment.
  • Less than 1% acid soluble impurities prevents mineral leaching deterioration.
  • Washed, kiln dried, and screened to meet exacting specifications.
  • High quality silica sand and consistent uniformity.
  • Meets or exceeds AWWA B100-09 standard and ANSI/NSF Standard 61 certification for quality and purity.

Uses

Water Filtration Media
Naturally clean, Red Flint water filtration media is known for its particulate removal properties and low acid solubility. The silica sand and gravel products are washed, kiln dried, and screened to meet exacting specifications with strict adherence to quality control.


Pool Filtration Media
Pool filtration media is a tightly-sized silica product that meets and exceeds quality and purity standards set by the American National Standards Institute and NSF International.

Aquarium Filtration Media
Red Flint #20 is used all over the world in aquariums such as the Georgia Aquarium and the aquarium underneath the Mall of America. Its colorful appearance and physical properties make it ideal for the smallest to largest aquariums.

Waste Water Filtration
Designers and manufacturers of advanced wastewater technologies use Red Flint granular filter material in their products and systems. The treated effluent is then returned safely to the environment. The quality of the water filtration media is tightly controlled and exceeds quality and purity standards set by the American National Standards Institute and NSF International.
