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® 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)


EP Minerals' PurifiDE® XG Purified Siliceous Earth USP-NF filter aids are designed for use with pressure filtration systems, to separate solids from aqueous or organic liquids --in situations where leachable impurities from standard food-grade diatomite could negatively impact the filtrate. The use of PurifiDE® XG Purified Siliceous Earth...

  • Save time and resources with longer cycle-times and higher flow rates compared to food-grade DEs with similar permeabilities
  • Reduce usage compared to conventional DE filter aids (lower density of PurifiDE® XG, means less product is needed to form equivalent filter cake volume)
