Manufactured by EP Minerals, Celatom diatomaceous earth filter aids are freshwater diatomite designed for the maintenance of filter cake permeability through the body feed addition of the Celatom media upstream of the filter press, filter housing or vessel. The use of filter aid becomes critical when filtering fluids with compressible and extremely fine solids. Celatom diatomite is particularly well suited for both pressure and vacuum filtration in food grade, beverage, and industrial applications.
