Frequently Asked Questions

Important information about Diatomaceous Earth, grades and applications.

Diatomaceous earth is a naturally occurring siliceous sedimentary rock made from fossilized diatoms — microscopic single-celled algae with silica shells.

Yes, food-grade diatomaceous earth is safe for use in food processing and filtration. It meets strict purity standards for human consumption applications.

DE works as a mechanical insecticide — the microscopic sharp edges damage insect exoskeletons, causing dehydration. It's non-toxic and residue-free.

Calcined DE is heat-treated at high temperatures to increase hardness and abrasiveness, used primarily in filtration and polishing applications.
