Diatomite is a fossil diatomite deposit formed after the death of a single celled plant called diatom and a accumulation period of about 10000 to 20000 years. Diatoms are one of the earliest protozoa on the earth. They live in seawater or lake water. They create 70% of the oxygen on the earth. During the growth process, it continuously absorbs the free silicon in the water to form a solid and porous cell wall. After the end of the diatom life cycle, the cell wall will not decompose and deposit to the underwater bottom. Diatomite is formed through crustal changes.

1.Food filter aid. Diatomite has strong adsorption capacity, so it is used as filter aid in food industry to remove bacteria, impurities and peculiar smell.
2.In environmental protection industry, diatomite is used for sewage treatment.
