1.Introduction:
Diatomaceous Earth or DE is the skeletal remains of single celled plants called diatoms, hence the name diatomite. These microscopic algae have the capability of extracting silica from water to produce their skeletal structure. When diatoms die their skeletal remains sink to the bottom of lakes and oceans and form a diatomite deposit. Natural diatomite is mined from deposits, that were formed millions of years ago, that were once lake and ocean bottoms. Silica (sand) is the most abundant compound on the earths crust. Natural diatomite is comprised of 85% silica the balance being other inert oxides.
