Description

In general, CELITE, diatomite (diatomaceous earth) has a more intricate particle shape and thus provides a more tortuous path for suspended particles to be trapped. HARBORLITE (expanded amorphous aluminum silicate) will usually handle similar filtration tasks but cannot always achieve the same removal efficiency. Fibra Cel, cellulose fiber is generally used in high temperature, highly alkaline environments where filter aid solubility would be a problem. Why doesn't one grade of filteraid handle all applications? Because filtering is basically a surface trapping phenomena (over simplified) and thus one always strives to use a filter aid that has a median pore size (the opening of the tortuous channels) just slightly smaller than the average particle size of the suspended matter that you are trying to remove. Diatomaceous Earth (CELITE, diatomite) has many grades to select from for the specific application. Who is the manufacturer of CELITE, diatomaceous earth (diatomite)? World Minerals Incorporated, of Santa Barbara, California is the largest manufacturer of diatomaceous earth in the world. see info@worldminerals.com
