Diatomite filter aids are processed in a kiln above 800°C (1500°F). Both calcined and flux-calcined diatomite filter aids are free of organic matter and are non-adsorptive. Filtration using diatomaceous earth has been done for more than 100 years. For many products it is the most cost effective filtration available today.

Diatomite filter aids usually work best with a precoat slurry concentration in the 0.3–0.6 wt.% range. This slurry then goes to the filter where the filter medium captures the solids. The clean filtrate returns to the precoat tank. The precoat should be thick enough to ensure the medium's entire surface is coated but thin enough to avoid ...

Diatomaceous Earth (DE) filtration is a process that uses diatoms or diatomaceous earth—the skeletal remains of small, single-celled organisms—as the filter media. DE filtration relies upon a layer of diatomaceous earth placed on a filter element or septum and is frequently referred to as pre-coat filtration.

Diatomite has been used as a filter aid for nearly a century. The ore is a soft, friable siliceous mineral. It is composed of the skeletons of microscopic plants deposited on the bottoms of oceans and lakes after and during the Miocene Age, from 100'000 to 15'000'000 years ago. Under the microscope the particles of diatomite show up in a ...
