About Diatomaceous Earth

Understanding the fundamentals of diatomaceous earth

Product Overview

The Remarkable Fossil Mineral

Diatomaceous Earth (DE) is a naturally occurring siliceous sedimentary rock composed of fossilized remains of diatoms — microscopic aquatic organisms.

Its unique porous structure, high surface area, and low density make it invaluable for filtration aids, absorbents, functional fillers, and pest control applications.

01

What is diatomaceous earth?

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

Natural Fossil Silica
02

Is food grade DE safe?

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

Food Safe Approved Pure
03

How does DE work for pest control?

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

Mechanical Natural Safe
04

What is calcined DE?

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