Diatomaceous earth (DE) filtration is a special filtration process that removes particles from liquids as it passes through a layer of fossilized remains of microscopic water organism called diatoms. These diatoms are mined from diatomite deposits which are located along the Earth's surface as they have accumulated in sediment of open and moving bodies of water. Obtained diatomaceous earth is then purified using acid leaching or liquid-liquid extraction in order for it to be used in any form of application. The process of D.E. filtration is composed of three main stages: pre-coating, body feed, and cleaning.[1]
Due to the precision of diatomaceous earth filtration; being able to capture dangerous and microscopic particles while maintaining efficiency has allowed D.E. filters to be a highly popularized choice for aquariums, wastewater treatment, food and beverage filtration, and more.
