Whole Grain Silica
Low Iron Whole Grain Silica
Whole grain silica is available in round, angular and sub-angular grain shapes and size distributions to meet many application requirements.
In order to effectively serve a wide spectrum of industries, we closely monitor screen sizing for consistent particle size and distribution.
Our whole grain sands have fewer impurities than many competitor products:
- Very low Fe2O3 (< 85 ppm)
- Low Al2O3 (< 250 ppm)
- Less than 2 ppm coloring oxides
- Low alkali and alkaline earths
- Low transition metals
FilPro® filtration silicas and gravels are engineered to optimize the performance of air scour potable water filters and tertiary filter systems.
