special filteraids for precoating the filter elements.  They consist
of a standard Dicalite diatomite filteraid mixed with a percentage
of selected acid-washed asbestos fibers or non-acid-washed
asbestos (at the option of the user).  The fibrous particles
readily bridge the coarsest septum openings to form a most
effective precoat.”; “Diabestos special precoat filteraid is a
mixture of Dicalite diatomite filteraids and asbestos selected for
high quality and filtering characteristics.  The asbestos (acid-
washed) has an extremely low alkaline and metallic content,
which is an important factor in filtrations of wine, beer, etc…”;
Dicalite Asbestos Filteraid Grades “These are available in two
100% chrysotile acid-washed grades and one non-acid-washed
grade.  Two grades of filteraids are available consisting of 50%
Solka-Floc and 50% acid-washed or non-acid-washed asbestos.  
All Dicalite asbestos filteraids are made from fibers specially
selected for highest quality and efficient filtering characteristics.”
