Diatomaceous earth filters are a type of filtration system that uses a natural substance called diatomaceous earth. This material is made from the fossilized remains of tiny aquatic organisms known as diatoms. When used in filters, it effectively traps impurities and particles from liquids, making it popular in various industries, including water treatment and food processing. These filters work by allowing water to pass through a layer of diatomaceous earth, which has a porous structure. The tiny pores capture contaminants while allowing clean water to flow through. This method is efficient and environmentally friendly, as it relies on a natural material rather than synthetic chemicals.
