Kieselguhr, also known as diatomaceous earth, is a naturally occurring siliceous sedimentary rock used as a filtration medium in various industries due to its high porosity and ability to trap fine particles. It is commonly employed in the production of beer, wine, and food products to clarify liquids by removing yeast and other impurities. In the chemical industry, it serves as a filter aid for purifying oils, solvents, and other liquids. Kieselguhr is also utilized in water treatment processes to remove contaminants and improve water quality. Additionally, it finds application as an absorbent for spills, particularly in hazardous material cleanup, due to its ability to soak up liquids efficiently. In agriculture, it is used as a carrier for pesticides and fertilizers, as a natural insecticide for pest control, and to improve soil quality, ensuring even distribution and effectiveness. It is incorporated as an additive in paints, rubber, plastics, and construction materials to enhance strength, durability, and chemical resistance. Its abrasive properties make it suitable for use in polishes and cleansers, while its thermal resistance allows it to be incorporated into insulation materials.
