DE celatom_diatomite

Diatomaceous Earth

Diatomaceous earth (DE), is a filtration media composed of microscopic diatoms silica structures millions of years old. DE is used in the beer industry as an extremely effective economical filtration media to facilitate liquid-solid separating. DE’s uniquely strong cylindrical shape, high pore volume and low resistance to flow make it the go-to filter medium.

  • Diatomite has been used as a filter aid for nearly a century.
  • The ore is a soft, friable siliceous mineral composed of the skeletal remains of microscopic plants deposited on the bottoms of oceans and lakes during the Miocene age.
  • Diatomaceous earth is amorphous silica with varying particle shapes and has the ability to form highly permeable, but rigid and incompressible filter cakes, which translates into efficient and economical filtrations.

Application: Two-step operation; first added as a protective layer (pre-coat), and then to maintain porosity (body-feed in pressure filters).

Packaging: 50 lb. bag & 1000 kg super sack
