Diatomite is a type of soil that consists of the fossil remains of single-celled algae belonging to the family of bacillariophys algae, which contains significant amounts of silica in its structure, and its sediments are in the form of fine grains. In addition to silica, small amounts of organic matter, clay and in some cases volcanic sediments are also observed in its structure.

Since this soil is made up of cell walls, it can be turned into powder. In most cases, it is in the form of white powder, and its particle size is 5 to 1000 micrometers, and it generally has a size between 50 to 100 micrometers, which are classified in different sizes according to different applications.

One of its prominent features is its high absorption power up to 2 times of its weight. The first production of diatomite soil back to 1884 using deposits in Maryland.

Coagulants can be clEach deposit of diatomaceous earth is different, with varying blends of pure diatomaceous earth combined with other natural clays and minerals.

The diatoms in each deposit contain different amounts of silica, depending on the sedimentation conditions, on the presence of other sediments (clay, sand, volcanic ashes), and on the age of the deposit (diagenesis, silica (SiO2) dissolution/precipitation, diatoms tests ageing). assified as organic coagulants and inorganic coagulants.
