Diatomaceous earth (DE) is a naturally occurring, organic powder that has been used for centuries in various applications, including filtration, pest control, and health supplements. However, with the increasing popularity of DE, many people are left wondering about the difference between diatomaceous earth and food grade diatomaceous earth. In this article, we will delve into the world of DE, exploring its composition, uses, and the distinguishing factors between the two types.
Introduction to Diatomaceous Earth
Diatomaceous earth is a soft, powdery substance composed of the fossilized remains of tiny aquatic organisms called diatoms. Diatoms are a type of algae that are found in both freshwater and saltwater environments. When diatoms die, their silica-based cell walls sink to the bottom of the water, where they are compressed into a fine, powdery sediment. This sediment is then mined and processed into the diatomaceous earth powder that is used in various applications.
Composition of Diatomaceous Earth
Diatomaceous earth is primarily composed of silica, with smaller amounts of other minerals such as alumina, iron oxide, and calcium oxide. The exact composition of DE can vary depending on the source and type of diatoms that are used to produce it. However, in general, DE is made up of approximately 80-90% silica, with the remaining 10-20% consisting of other minerals and impurities.
