Filter Diatomaceous Earth

Product name: Filter Diatomaceous Earth

Product identification and description: 

Diatomaceous earth is an unconsolidated diatom soil formed in the Tertiary freshwater sea by the deposition of microscopic siliceous shells of unicellular algae (diatomacei), as well as siliceous needles of fungi, with these porous shells containing organic and inorganic admixtures to varying degrees. The diatomaceous earth deposit in the borovansko-ledenické basin is located in the subsoil of clay raw material and is the only mined site in Central Europe. 

The basic building material of diatomaceous earth is SiO2 in an amorphous structure (SiO2·nH2O). It is characteristic of all types of diatomaceous earth that they are very fragile after drying, as their individual parts are very porous. 

According to quality and bulk density, we distinguish between diatomaceous earth, which is intended for the production of filter materials and fillers, and diatomaceous earth, intended for the production of litter, sorbents and for construction and agricultural purposes. The sorted and homogenized raw material is treated by wet cleaning, drying, flux calcination and wind sorting.
