Celatom® Filter Natural (FN) diatomaceous earth (DE) grades are low crystalline-silica, low permeability products, used primarily as filter aids in filtration. These natural products are off-white in color and have a permeability range of 30-115 millidarcy.

  • Low crystalline-silica
  • Low permeability
  • Natural filter aid

Celatom® Filter Pink (FP) grades of diatomaceous earth (DE) are calcined and light pink. These grades make for an excellent filter aid, especially as a polish filter aid. Permeability is between 60-1300 millidarcy. Filter Pinks are produced at both our Lovelock and Vale plants, for flexibility in ordering.

  • Calcined diatomaceous earth
  • Light pink color
  • Excellent for filtration, especially polish filtration

Celatom Filter White (FW) flux-calcined diatomaceous earth (DE) ranges in color from bright white to light pink. These filter aid grades have a wide range of filtration capabilities and a wide range of particle size removal properties. Our filter white products have a permeability range of 420-20,000 millidarcies.

  • Wide range of filtration capabilities
  • Wide range of particle size removal
  • Permeability range of 420-20,000 millidarcies

Celatom® Floc grades are specialty, high-purity, chemically inert filter aid used to complement other filter aids, such as diatomaceous earth and perlite. They were developed to function as a primary precoat and/or bodyfeed. We offer three grades to best meet your application needs.

  • Simply... Clearer, Faster
  • Reduces the time required to precoat the filter
  • Improves the stability of the precoat
  • Eases precoat cake release
  • Improves adsorption of trace metals

Celatom® Perlite is a hydrated, naturally-occurring volcanic rock. Its unique structure consists of numerous concentric layers, similar to the layers in an onion. Its natural color ranges from light pearl gray to dark gray. The distinguishing feature which sets perlite apart from other volcanic siliceous rocks is that when heated...

  • Very low "dry & wet" bulk densities
  • Essentially 'zero' crystalline silica (<0.05%)
  • Higher solid holding capacity in coarse applications
  • Works well in coarse non-critical filtrations and dewatering applications (wastewater)


PurifiDE®, our purest diatomaceous earth filter media (permeability 300 mD or 1200 mD) are used for filtering high value liquids where extractable elements are of concern. PurifiDE is manufactured using proprietary and controlled manufacturing and quality control processes to meet USP-NF standards for Purified Siliceous Earth....

  • Plasma fractionation
  • Clarification of cell culture supernatants, and fermentation broths
  • Purification of delicate oils sensitive to oxidization
  • Filtration of cell culture media components, including peptides and peptones
