Diatomaceous earth (DE), also known as diatomite, diahydro, kieselguhr, kieselgur and Celite, is a sedimentary rock primarily composed of the fossilized remains of unicellular fresh water plants known as Diatoms.
The typical chemical composition of diatomaceous earth is 86% silica, 5% sodium, 3% magnesium and 2% iron.
The De has a high porosity, with lower density, larger surface area, strong absorption, good suspending performance, it has relative incompressibility and chemical stability without any poison and smell.
Therefore, the diatomaceous earth and its products are used as a filter medium, especially for swimming pools. It is also used to filter beer,wine,glucose,syrups and sugar. Other industries such as paper, paints, ceramics, soap and detergents use it as a filling material.
It has been widely used to decolor and refine of the animal oil and fat, plant slipid and cosmetic raw material, petroleum industry, chemical industry for daily use, it has also been used in sewage disposal, filter noxious gas and catalyze petroleum in grain.
