Good quality diatomaceous earth/diatomite filter aid

Diatomite has been used as a filter aid for nearly a century. Under the microscope the particles

of diatomite show up in a variety of forms: symmetrical figures resembling disks, rods, cylinders

and snowflakes. It is this shape factor combined with the rigidity of the particles that makes diat-

omite such an excellent raw material for the production of superior filter aids.

Diatomaceous earth is an amorphous form of silica containing a small amount of microcrystalline

material. Filter aids are processed at above 800 °C (1500 °F). Both calcined and flux-calcined

diatomite filter aids are free of organic matter and are non-adsorptive.

Dicalite diatomite filter aids offer outstanding performance from the finest to the coarsest grades.

These materials meet all requirements for good filter aids.
